Film Set Fundamentals

Introduction

A film set is the most organised workplace in this industry and the least forgiving of somebody who does not know how it works. Several hundred people can be standing in one room, and all of them know exactly whose equipment they may touch, which words stop everything, where the camera can see, and what happens next. A newcomer who does not know those things is not merely unhelpful. They are expensive.

You are arriving with a real craft. Signal flow, video systems, monitors, media, networks, power and comms are all on a film set, and the roles that use them — video assist, the video village, the DIT, playback, prompting, and the whole of virtual production — are among the fastest-growing jobs in film. What you do not yet have is the set: its departments, its language, its paperwork, its day, and its particular safety culture.

What this book covers

• Who every department is, who leads it, and whose gear is whose.
• The paperwork a day runs on — the call sheet, the sides, the schedule and the production report.
• The calls, from "quiet please" to the martini, and what each one asks of you.
• The shape of a shooting day, setup by setup, from call to wrap.
• The video jobs an AV professional is hired for, and how to do them.

• Video village and video assist, built as a signal chain.
• Media handling, offloads and the chain of custody the DIT owns.
• Playback and prompting, including content the camera photographs.
• Virtual production, LED volumes and the brain bar.
• Film's safety bulletins, exclusion zones and who can stop work.

Who this is for

Anybody with AV skills who wants to work in film and television: technicians moving across from live events, camera and video people taking their first set job, and crew who already work on sets and want the parts nobody explained. It assumes you have read Set & Stage Etiquette, or that you already conduct yourself well on a crew.

How to Use This Book

Read it once through before your first set day, then use it as a reference. The chapters follow the order you will meet things: who everybody is, what the paperwork says, how the floor talks, how the day runs, and then the jobs you will actually be doing.

Keep a notebook

Write down the calls you hear, the names of the people you meet with their roles, the channel numbers on the radio, and the layout of the video village you built. Sets repeat: the same words, the same rhythm, the same connections. A notebook turns your first three days into a working method.

A note on the words

Film has its own vocabulary, and much of it is regional. The words in this book are the common North American and British set terms, which are understood almost everywhere. When somebody uses one you do not know, ask afterwards rather than during a take.

A note on safety

Film sets carry the same hazards as any production — weight in the air, work at height, mains power, moving vehicles, long hours — plus firearms, pyrotechnics, stunts and effects that are run by specialists under written industry safety bulletins. Nothing in this book qualifies you to do any of that work. It teaches you to recognise it, to stay outside the exclusion zones, and to know that anybody on a set may call to stop unsafe work.

Where this book sits

This book assumes you conduct yourself well on a crew, as Set & Stage Etiquette teaches, and that you know what a camera, a monitor and a signal chain are. It does not assume you have ever been on a film set.

What pairs with this

• Set & Stage Etiquette — the conduct that carries across film, events and theatre
• Signal Flow & System Architecture — the chain behind video village, playback and the volume

Where it leads

These are not steps in an order. Take whichever one fits.

Before You Begin

How a Film Set Works

A film set looks like chaos to somebody who cannot see the structure, and like a machine to somebody who can. Perhaps two hundred people are in a street or a stage, and every one of them belongs to a department that owns one part of the picture. Nobody is idle and nobody is freelancing: the grips are shaping light, the electricians are feeding power, camera is building the shot, sound is listening, the ADs are running the clock.

This chapter names every department you will meet, says who leads it, draws the two chains of command a set runs on, and — most usefully for a newcomer — makes clear whose equipment you may put your hands on.

A film set is a large, organized team of departments, each with a clear job.

The departments

A film or TV set is organized into departments, each responsible for one aspect of making the film, working together under the director's vision. The camera department captures the image (operators, assistants, focus pullers). Grip and electric (G&E) handle rigging and lighting — grips rig and support gear and shape light with flags and frames, electricians (gaffers and their team) provide power and run the lights. The sound department records the production audio (the boom operator, the sound mixer). Other departments include art (sets and props), wardrobe, makeup, and more. Each department has its own crew, lead, and clear responsibility, and they combine to capture each shot.

Understanding the departments tells you how a set is organized and where everyone fits. A film set can have dozens or hundreds of people, and it works because each department knows its job and they coordinate. For an AV professional stepping onto a set, knowing the departments — especially camera, G&E, and sound, plus the AV/video roles covered later — orients you to who does what and where you fit. The departmental structure is the skeleton of how a set operates.

Here is the fuller list, in the order you will meet them on a call sheet. Production is the office: the producers, the unit production manager who runs the money and the logistics, the production coordinator who arranges everything, and the production assistants who make it happen on the ground. The assistant directors run the floor: the first AD, the second AD, and on bigger shows a second second AD and a set PA.

Camera is the director of photography, the camera operator, the first assistant camera who pulls focus, the second assistant camera who slates and marks, the loader who handles media, and on digital shows the DIT and video assist. Grip is the key grip, the best boy grip, the dolly grip and grips, who rig, support and shape — flags, frames, nets, stands, dollies and track. Electric is the gaffer, the best boy electric and the electricians, sometimes called juicers or sparks, who provide power and run every light. Together the two are called G&E.

Sound is the production sound mixer, the boom operator and the sound utility. Art covers the production designer, the art director, the set decorator, the property master and the construction crew. Costume, hair and makeup, locations and transportation each have their own leads. The script supervisor tracks continuity and what has been shot. Stunts, special effects and visual effects appear on the days they are needed, each with a supervisor who owns their work absolutely.

The hierarchy and chain of command

Film sets have a clear hierarchy, and understanding the chain of command is essential. At the top of the creative side is the director (who directs the creative vision), supported by the first assistant director (1st AD) who runs the set operationally — keeping the day on schedule and calling the shots procedurally. Each department has a head (the director of photography or DP leads camera and overall image; the gaffer leads electric; the key grip leads grip; the sound mixer leads sound), and crew within each department report up their department's chain. Knowing who leads what, and who you report to, is how you function on a set.

This hierarchy keeps a large, complex operation coordinated, much like the production hierarchy you met in AV Fundamentals, with film-specific roles. As a crew member, you take direction through your department's chain of command, respect the 1st AD who runs the floor, and understand the director's authority over the creative. For an AV professional in a video role on set, you fit into this structure — knowing the hierarchy lets you work within it professionally. Respecting the chain of command is fundamental set conduct.

Grip and electric, and the line between them

Grip and electric work side by side all day and are constantly confused by outsiders. The distinction is simple once heard. Electric makes light: they run power, place lamps, and control them electrically. Grip shapes light and supports things: flags, nets, silks, bounce, stands, clamps, dollies and track. If it plugs in, it is usually electric's. If it blocks, holds or rolls, it is usually grip's.

The two departments have their own carts, their own stands, their own tape and their own gloves, and each is proud of its own kit. A video person who borrows a C-stand from grip without asking, or unplugs something from an electric distro to power a monitor, has made the classic newcomer mistake. Ask. Both departments are usually glad to help a video operator who asks and furious with one who helps themselves.

You will also hear the rigging crew, a separate grip and electric team that pre-rigs a location before the shooting crew arrives and strikes it afterwards. On big shows they are a different set of people on a different schedule, and the gear they leave behind is theirs.

The camera department, role by role

The director of photography, the DP or cinematographer, owns the image: the lighting, the lens, the exposure and the look. The camera operator frames and moves the shot. The first assistant camera, the focus puller, keeps the image sharp and looks after the camera build. The second assistant camera runs the slate, marks the actors, changes lenses and keeps the camera reports.

The loader takes media from the camera and hands it to the DIT, who copies, verifies and often applies colour on set. Video assist takes the camera's picture out to the monitors everyone else watches, and records takes for playback and review. Those last two roles are where most AV people start, and they are the subject of their own chapters later in this book.

The department is a chain and it works at speed. Your video feed comes from their camera, your monitor cables run past their cases, and your timecode comes from their sound department. Treat the camera crew as the people you serve, tell them before you touch anything of theirs, and they will keep you working.

The production office and the crew list

The people who hire and pay you are rarely on the floor. The line producer and unit production manager run the budget and the crew. The production coordinator and the production office handle bookings, travel, purchase orders, gear rentals and the endless paperwork that lets the shoot happen.

You will hear the crew split into above the line and below the line. Above the line is the small group whose deals are negotiated individually and whose names sell the film: the producers, the director, the writer and the principal cast. Below the line is everybody else — the crew, the gear, the trucks and the days. It is a budgeting term that has become a cultural one, and video, data and playback sit firmly below the line.

A day player is hired for a day at a time. A deal memo sets the rate, the hours and the terms, and it is signed before the first day, not afterwards. Dailies are the day's footage made available for review — the reason the DIT's work has a deadline every night.

The two chains of command

Two chains run in parallel and a newcomer must hold both. The creative chain is the director, through the department heads, to the crew: what the film looks and sounds like. The operational chain is the first AD, through the second ADs and the PAs, to everybody on the floor: where people stand, what happens next, and when.

The frame belongs to the director. The floor belongs to the first AD. You take your work direction from your own head of department. If the director asks you directly for something, you do it and you tell your head of department; if anybody else asks you to do something outside your department, you refer it to your lead. Nobody is offended by that answer on a professional set.

Who leads each department

The head to find if you need something from that department. Titles vary a little by country and by production size.

Grip or electric?

The quickest test when you do not know whose equipment you are looking at.

On the job

Your first day on a commercial. You arrive at a warehouse location at 07:00 and see a hundred people doing unrelated things. Trucks are parked along one wall, a man is winding cable, two people are arguing about a window, and nobody is filming anything.

By the end of the morning you can read it. The cable is electric running a feeder to a distro. The argument is the DP and the key grip deciding how to flag daylight off the glass. The people building the small tent with monitors are your job, and the person who keeps looking at her watch and calling "we're losing the morning" is the first AD, who runs the day.

At 09:40 the second AD asks you to move your monitor cart three metres because the background artists have to walk through where you set up. You move it, because the floor is the AD's, and you tell the DIT where you have gone, because your feed comes from his cart.

How to do it

1. Find your own head of department first and tell them you have arrived.
2. Ask which channel your department is on, and put the radio on it.
3. Walk the set once and note where camera, sound, grip, electric and the ADs have based themselves.
4. Find the video village position, the power you have been given and the route your cable will take.
5. Ask the first AD's team where you may and may not put a cart.
6. Introduce yourself to the 1st AC and the DIT; your picture comes through them.
7. Find the toilets, the exits, the medic and craft services before you need them.

What goes wrong

Practice it

Test yourself on the structure before your first day.

The Paperwork and the Plan

A film day is planned on paper before anybody picks up a camera, and the paper is public. A day's plan names when and where everybody starts, and what is being shot. The sides carry the scenes in a pocket-sized form. The schedule says what order the film is being made in, and the production report says what actually happened.

A newcomer who reads these documents knows more about the day than most people who only listen to the radio. Read them the night before, and again at breakfast.

The call sheet

The call sheet is issued the evening before for the following day, and it is the day's contract. At the top are the date, the production, the day number, the weather, sunrise and sunset. Then the crew call, the time work begins, and often a separate shooting call, the time the camera is expected to turn over. Each department may have its own call time — riggers earlier, some departments later.

The middle of the sheet lists the scenes being shot, in order, with their numbers, a one-line description, whether they are day or night, interior or exterior, the pages of script each one represents, and the cast involved. Below that come the cast list with individual calls for makeup, wardrobe and set, the background artists, and the special requirements — stunts, effects, animals, children, vehicles.

The back of the sheet is the part crews read most: maps and parking, the hospital address, the medic, the toilets, catering times, and the advance schedule for the following day. Read every line of it. Your call time, your parking, and whether tomorrow starts six hours after tonight's wrap are all there.

Sides, the schedule and the one-liner

Sides are the pages of script being shot that day, printed small and folded into a pocket. They carry the dialogue and action, and they are how the crew know what the scene is. Video people use them to know when a screen in the scene has to show something, and when a phone rings on camera.

The shooting schedule puts the whole film in the order it will be shot, which is almost never the order of the story. Films are scheduled by location, by cast availability and by daylight, so scene 84 may shoot on day two and scene 3 on day twenty. The one-liner is the compressed version, a line per scene, used for planning.

The day out of days is a grid of who is needed on which day — cast, stunts, effects — and it tells a department when its heavy days are. If you are running playback for a scene with screens in it, the day out of days tells you which days those screens exist, and therefore when your content must be finished.

The production report and what it records

At the end of every day the second AD files a production report: the times the day actually ran, the scenes and pages completed, the takes printed, meal breaks and penalties, injuries, and anything that cost the production time. It is the record used to decide whether the film is ahead or behind.

This matters to a video operator for one reason: delay is measured and attributed. A department that holds the camera for ten minutes appears in the report. It is not a punishment system, but it is a memory, and it is why "we are ready" has to be true when you say it.

Reading the day before you arrive

Do the following the night before, in ten minutes. Read your call time and the location, and check the route and the parking. Read the scenes and look for anything that involves a screen, a phone, a monitor, a projection or a prompter, because those are yours. Check the weather, because an exterior day in rain changes what you bring. Check the advance schedule for what happens tomorrow.

Then pack for it. A video village on an exterior day needs sun hoods, weather cover and more battery than a stage day. A location with a long walk from the truck needs a cart that rolls on rough ground.

What the call sheet tells you

Every line of a call sheet exists because somebody once did not know it. These are the ones a video operator reads first.

The documents of the day

Four pieces of paper, and what each is for.

On the job

You are running playback on a corporate drama. The call sheet for day four lists scene 31, an office interior, with the note "practical screens" beside it. You read the sides and find that in the scene a manager turns a monitor towards an employee to show a bad quarterly chart.

That is your work: content on a screen the camera photographs. You raise it at the production meeting two days before, ask the art department who is supplying the monitor and what its resolution is, ask the DP what frame rate and shutter the scene shoots at, and get the chart artwork from the production designer.

On the day, the screen shows the chart, it does not flicker on camera, and the scene is shot in four takes. Nobody notices you, which on a set is the compliment.

How to do it

1. Read your department's call time and the location address.
2. Check the route, the parking and how far the walk from the truck is.
3. Read the scenes and the sides, looking for screens, phones, prompters and playback.
4. Note the cast calls, because quiet starts when talent arrives on set.
5. Check the special requirements for stunts, effects, children or animals near your position.
6. Check weather, sunrise and sunset for exterior work.
7. Read the advance schedule and check your turnaround.
8. Pack for the day you have just read, not for a generic one.

What goes wrong

Practice it

Take any call sheet you can find, or the one from your next job.

On-Set Protocol

Protocol on a film set is not manners. It is the set of behaviours that keep a very expensive machine running: a ruined take costs a crew's time and sometimes daylight that cannot be bought back. Most of it comes down to three things — be where the camera cannot see you, be silent when it matters, and touch nothing that is not yours.

This chapter adds the specifics behind those rules: what "the shot" actually includes, how to move around a lit set, how the radio works, and what happens with phones and photographs.

Sets run on protocol — knowing it marks you as someone who belongs.

The calls and quiet

Film sets run on a set of calls and protocols that everyone must know and obey instantly. When the 1st AD calls for quiet and the camera is rolling, absolute silence and stillness are required — any noise or movement can ruin a take (and film takes are expensive to redo). Calls like quiet on set, roll sound, rolling, and action signal the shooting moment, and cut ends it; everyone responds to these immediately. Respecting the rolling protocol — silent and still when a take is happening — is the most fundamental on-set rule, and violating it is a serious breach. This is ordinary set etiquette in its strictest film form.

Other protocols govern the set: not walking through shots, staying out of the camera's view and the lighting, not touching other departments' gear, and being where you need to be without being in the way. Learning these protocols — by knowing them and by watching experienced crew — is how a newcomer shows they belong. The set has a culture and a way of operating, and respecting its protocols, especially around rolling and quiet, is essential professional conduct on a film set.

Set etiquette and professionalism

Film-set etiquette extends the professionalism from Set & Stage Etiquette to the specific culture of a set. Be reliable and on time (call times are strict — being late is a serious problem). Stay in your lane (do not touch other departments' gear or do work that is not yours). Hurry up and wait (sets alternate between intense activity and waiting; be ready instantly and patient otherwise). Be quiet and unobtrusive (a set is a focused workplace, not a social one, especially near the action). Respect the hierarchy and the talent. These behaviors mark you as a professional who can be trusted on set, and getting them wrong — even technically skilled — gets you not invited back.

Sets are also intense, long, and demanding, and professionalism under those conditions matters: staying focused, positive, and reliable through long days and pressure. The film industry is relationship-driven and reputations travel fast, so conducting yourself professionally on every set is how you build a career in film. For an AV professional joining a set in a video role, bringing this set-appropriate professionalism — alongside your technical skill — is what makes you welcome. Etiquette is as important on a film set as anywhere in the industry, and arguably stricter.

The shot, the eyeline and the frame

"Staying out of the shot" is bigger than it sounds. The camera sees a frame, but the shot also includes everything the light touches and everything an actor can see. Walking behind a camera is usually fine. Walking behind an actor, in their eyeline, is not: it pulls their attention and it can end a take as surely as a noise.

Ask the second AC or the operator where the frame ends if you cannot tell. On a marked set there are often taped lines on the floor showing where the camera sees. Learn to read a lens: a wide lens sees far more of the room than a long one, and a set that was safe to stand in an hour ago may not be after the lens changes.

You will also hear lock-up: the AD team closing a doorway, a corridor or a street so nobody walks through. If somebody is locking up an area you need, tell them before the take rather than walking through it during.

Moving on a lit set

A lit set is full of cable, stands and hot lamps, and it is usually dark where the light is not pointed. Film has its own calls for moving through it, and using them marks you as somebody who belongs: "points" when you carry anything with ends that could hit somebody, "striking" when you are switching on a bright light or removing something, "hot points" for anything hot, "flashing" when a flash or strobe is about to fire, and "coming through" when you move behind people who cannot see you.

Never step over cable — step around it, or it moves under your foot at the wrong moment. Never move a stand, a flag or an apple box without asking; it is holding something in a position somebody spent twenty minutes finding. And when you put your own cart down, put it where it does not block a walkway, a door or the path from the truck.

Radio and channel discipline

Sets run on radios with several channels: channel 1 is usually the main production channel, with departments on their own channels beyond it. Learn which channel your department uses and stay on it, monitoring 1 if you are asked to.

The etiquette is short: name who you want, then yourself — "video, first AD" — wait for their answer, and keep it brief. Use the channel for work, never for chat. And understand the common shorthand: copy for received and understood, standing by for ready and waiting, 20 for location, 10-1 for a bathroom break, flying in for anything moving overhead, and back to one for everybody to reset.

Phones, photographs and confidentiality

Film sets leak through crew phones, and productions take it very seriously. Almost every set you work on will require a non-disclosure agreement, and many now collect phones or apply camera covers on secure productions. The rule is simple and absolute: no photographs of the set, the cast, the script, the monitors or the schedule, and nothing posted anywhere, ever, unless the production has explicitly released it.

This includes your own work. A photograph of a beautifully built video village shows the set, the monitors and often the frame itself. Show it to nobody until the production is released, and even then ask.

Phones are also a noise and light source. On set, on silent, in a pocket — not in your hand where a screen glows in a dark corner and not in the frame of a long lens.

The moves you call out

Say them loudly, before you move, and respond when somebody else says them.

Radio shorthand

The words you will hear in your first hour, and what each means.

On the job

A night exterior, a narrow street, a long lens. You need to move your monitor cart from one side of the street to the other because the camera has turned around and your cable no longer reaches.

You wait for the AD to call a cut and a reset, then you tell the second AD what you need. You call "points" as you lift the stand, "coming through" as you pass behind the sound cart, and you take the long way round rather than crossing the lit area, because on a long lens the background is the shot.

It takes ninety seconds. Crossing the street directly would have taken twenty and put you in the frame of the next take.

How to do it

1. Wait for a cut or a reset unless it is a safety matter.
2. Tell the AD team, and your own lead, what you are about to move.
3. Look up before you lift, and look at where the camera is pointing.
4. Call "points" or "coming through" as you move.
5. Walk around the lit area rather than through it.
6. Re-dress your cable so it does not cross a walkway.
7. Tell the DIT or the 1st AC if your move changed where your feed comes from.

What goes wrong

Practice it

Say what you would do in each case.

The Language of the Floor

A film set is run by voice. The first AD calls a sequence of words, each one asking something specific of somebody, and the day moves through them dozens of times. Learning the sequence is the single fastest way to stop feeling lost, because at any moment you can tell exactly where in the cycle the set is and what is about to happen.

This chapter is the vocabulary: the calls in order, the slang that tells you how much day is left, and the words that mean stop.

The calls, in order

A take runs through the same sequence every time. The AD calls "final checks" or "last looks", and hair, makeup and wardrobe step in for a few seconds. "Lock it up" closes the area. "Quiet please" or "settle" stops all noise. "Roll sound" starts the sound recorder, and the mixer answers "speed" or "sound speed" when it is up.

"Roll camera" follows, and the operator or assistant answers "rolling" or "camera speed". The second AC steps in with the slate, the AD or the AC calls "marker" or "mark it", and the clapper closes. Then, and only then, the director calls "action" — and nobody else ever does.

At the end, the director calls "cut". The AD will then say either "going again", in which case everyone resets and you hear "back to one", or "moving on", which means the setup is finished and the next one begins. "Check the gate" is the old film call to inspect the lens gate for hairs before moving on; on digital shows you will still hear it used loosely to mean "confirm we have it".

How much day is left

Film has a private vocabulary for the end of the day, and it is genuinely useful. The abby singer is the second-to-last shot of the day, named after a production manager famous for calling it. The martini is the last shot — the next one is in a glass. When you hear either, you know how long you have and can begin planning your own wrap.

Turnaround has two meanings and you must hold both. Between days, turnaround is the rest period between wrap and the next call, and it is contractual. Within a scene, a camera turnaround is reversing the setup to shoot the other direction, which usually means moving lights, moving the camera and moving you.

Company move is the whole unit relocating to another location, usually with a hard deadline and a truck. MOS is a shot taken without sound. Room tone is a minute of silence recorded by sound at the end of a location, and it is the one time the whole crew must be absolutely still with nothing happening at all.

The people words

First team is the actors; second team is the stand-ins, who occupy the actors' positions while the scene is lit. Background or BG are the extras. When the AD calls "first team in", the actors are arriving and the set goes quiet and focused.

Crafty is craft services, the snacks and drinks table. Basecamp or the circus is where the trucks, trailers and catering live, often streets away from the set itself. Video village is your world: the monitors where the director, the DP, the script supervisor and the clients watch.

Hot set means a set that has been dressed and lit and must not be touched, even if a chair looks out of place — continuity depends on it staying exactly as it is. If you see a sign saying hot set, put nothing on it, move nothing, and route no cable across it without asking.

A take, call by call

The sequence runs the same way every time. Read down the column and you can follow any set in the world.

Set slang worth knowing on day one

A short glossary of the words you will hear before lunch.

On the job

Mid-afternoon on a drama. You are re-dressing a cable when you hear the AD call "final checks", then "lock it up", then "quiet please". You stop where you are, cable in hand, and stand still.

"Roll sound." — "Speed." — "Roll camera." — "Rolling." — "Marker." — "Action."

Ninety seconds later: "Cut. Going again — back to one." You stay still through the reset, because the camera is still where it was and the actors are walking back to their marks. On the third take you hear "cut, moving on", and only then do you finish dressing the cable, before the lighting for the next setup starts and you lose your chance.

How to do it

1. At "final checks", stop what you are doing and make sure you are clear of the set.
2. At "quiet please", stop moving and silence your radio.
3. At "rolling", freeze completely — including mid-task.
4. Wait for "cut" before moving, breathing out or speaking.
5. Listen for "going again" or "moving on" — they mean opposite things for you.
6. At "back to one", reset anything of yours that the take changed.
7. At "moving on", do the work you were holding, quickly.

The Shooting Day

Every shooting day is the same five things repeated: block, light, rehearse, shoot, move on. The people change, the locations change and the scenes change, but the cycle does not, and it is the reason the day feels like long waits punctuated by sudden urgency.

This chapter puts times and structure around that rhythm, from the moment you park to the moment the truck doors close, and shows where a video department's work falls inside it.

A film set runs to a rhythm — knowing it helps you fit in and stay ready.

The rhythm of a shoot

A film shooting day has a rhythm worth understanding. It starts at call time (when crew must arrive, ready — strictly enforced). The day proceeds shot by shot: for each setup, the scene is blocked (the action and camera positions worked out), the set is lit and rigged (G&E work, which takes time), the shot is rehearsed and then shot in takes (multiple attempts to get it right), and then the production moves to the next setup (which may mean relighting and repositioning). This cycle repeats through the day until wrap (the end of the shooting day). Understanding this rhythm — setup, light, shoot, move on, repeat — tells you what is happening and what to expect.

A defining feature is hurry up and wait: there are intense bursts of activity (lighting a setup, shooting takes) punctuated by waits (while another department works, while a setup is prepared). The professional is ready to work instantly when needed and patient during the waits, never the cause of delay and never absent when called. Knowing the shooting day's rhythm helps you stay ready, fit into the flow, and understand why things take the time they do. The rhythm of the shoot is the daily reality of set work.

Fitting into the flow

Fitting into a film set's flow means understanding your role in this rhythm and being ready for it. In a video role (video village, DIT, playback), you have your own setup to do, your own work during takes (running monitors, managing data, handling playback), and your own readiness to maintain. You work within the shooting day's cycle, coordinating with the departments you interact with (camera especially), staying ready when the production needs you, and doing your part smoothly so you support the shoot rather than slowing it. Being a reliable, ready, professional part of the flow is what makes you valued on set.

This is the same readiness and coordination any AV job asks of you, applied to the film set's particular rhythm and culture. The AV professional who understands the shooting day, knows their role in it, stays ready, conducts themselves professionally, and delivers their technical work reliably fits seamlessly into a set. Combining your AV skills with this understanding of how a set runs is what lets you contribute on a film production rather than being a fish out of water. Fitting into the flow is how AV skills become useful on set.

The anatomy of a setup

A setup is one camera position. The day is counted in setups, and each one runs through the same stages. First blocking: the director and the actors walk the scene while the DP, the AD and the departments watch. Then marking: the second AC lays tape marks for where the actors stand and the camera sits.

Then lighting, the longest part, when grip and electric build the look while the stand-ins hold the actors' positions. Then rehearsal with the first team, then takes until the director has it. Then moving on: the camera is repositioned or turned around, and the cycle begins again.

Your work lands in specific places in that cycle. Video village must be up and feeding before blocking, because the director watches the rehearsal on it. Any repositioning you need happens during lighting, not during takes. And if the camera turns around, your monitors and cable probably move too — which you plan for during the lighting of the previous setup.

Call to wrap, hour by hour

A typical day starts with crew call, when work begins. Camera and the ADs may have been in earlier. Breakfast is usually available before the call, not during it. The first setup normally shoots one to two hours after call, and the AD is watching that gap closely — being ready is worth more than being fast later.

Lunch is called roughly six hours after crew call, and it is contractual: on union productions, working past that incurs a meal penalty paid to the crew, which the production works hard to avoid. The afternoon repeats the morning's cycle, often faster, and the end of the day brings the abby singer and the martini.

Wrap is not when the camera stops. It is when the gear is packed, the location is restored and the trucks are loaded, which for a video department means striking monitors, coiling cable, charging batteries overnight and confirming with the DIT that the day's media is secured. Then the clock starts on turnaround, the rest before the next call.

Hurry up and wait, from the video cart

The waiting has a shape. During lighting you have twenty minutes to an hour, and that is when you fix cable routing, swap batteries, label things, check your recordings and eat. During rehearsal and takes you are on duty and cannot leave your position. During a company move you are working hard while other departments wait.

The discipline is to do your slow work in the slow window. A video operator who is still tidying cable when the AD calls "final checks" has mistimed the day. Look ahead: read the next setup, ask camera where they are going next, and prepare for that position while the current one is lit.

Company moves and location days

A company move is the unit relocating mid-day. It has a hard deadline, and it is one of the few times the whole crew is doing the same thing at once. Video is usually among the first to strike and the first to be needed again at the new location, because the director wants monitors as soon as blocking begins.

Pack for the move as you build: cable in labelled loops, monitors in their case, a cart that rolls over the ground you were told about on the call sheet. On a location day, add weather cover, sun hoods for the monitors, tape to hold everything down in wind, and far more battery than a stage day needs.

The stages of a setup, and what you do in each

Whatever else is happening, a set is always doing one of these. Know which, and you know what you can do.

The day's landmarks

Six moments that structure every shooting day.

On the job

Day six, an interior office, four setups scheduled. Crew call 07:00.

You are built and feeding three monitors by 07:40, before blocking at 08:05. Lighting runs to 09:20, and in it you re-route your cable out of a doorway and swap a battery. First takes at 09:35. At 10:10 the AD calls a camera turnaround, and because you asked the 1st AC at breakfast which way they were going, your second monitor position is already cabled.

Lunch at 13:00, exactly six hours after call. Two more setups in the afternoon, the abby singer at 17:40, the martini at 18:15. You are packed by 18:50, having charged everything for tomorrow's 06:30 call, which you knew about because you read the advance schedule last night.

How to do it

1. Build and test before the first blocking, not after it.
2. Ask camera which direction the next setup goes, and pre-run cable for it.
3. Do slow work — routing, labelling, charging, eating — during lighting.
4. Be at your position, silent, from rehearsal onwards.
5. During takes, watch your own monitors: a dead feed is yours to notice first.
6. At "moving on", move with grip and electric, not after them.
7. Before wrap, confirm the media is secured with the DIT and charge everything.

AV & Video Roles on Set

This is the chapter about your job. Film sets hire AV people for a small number of specific roles, and each one is a craft you already half know: a signal chain, a monitor, a media workflow, a piece of content played on a cue. What makes them film jobs is the set around them — the camera department you serve, the director watching your monitor, and the pace.

This chapter names the roles. The chapters that follow take each in turn and show how it is actually done.

Where AV professionals fit on a film set: the image, the data, the playback.

Video village, DIT, and playback

AV professionals increasingly work on film sets in video and data roles, which is where your skills fit. Video village is the area of monitors where the director, DP, and others watch the camera's image live — setting up and running these monitor feeds (getting the camera's video to the right monitors cleanly) is a video role drawing on your signal-flow and video knowledge. The DIT (Digital Imaging Technician) manages the data and image on set — a major AV-adjacent role. Playback handles on-set video playback — playing content the production needs (a video on a screen in the scene, reference footage). These video-and-data roles are where AV craft meets the film set.

These roles draw directly on AV skills: video village uses video signal flow and monitoring; DIT uses data management and colour; playback uses the playback craft. The AV professional brings these skills to the set, fitting into the camera and post-adjacent side of production. Knowing that these roles exist — video village, DIT, playback, and the data/video side generally — shows you where your AV background lets you contribute on a film set, which is an expanding area as productions become more technical.

Virtual production and the expanding AV role

The AV role on film sets is expanding dramatically with virtual production — LED volumes, real-time engines, and the convergence of live AV and film. Virtual production has brought AV skills (LED, media servers, video systems) right onto film sets in a big way, creating whole new roles for AV professionals in film production. Beyond VP, the general trend is that film and television production is more technical and AV-driven than ever, with more video, data, and systems work on set. This makes the film set an increasingly relevant place for AV professionals, and understanding the set is increasingly valuable AV knowledge.

For an AV professional, this means film sets offer real opportunity — in video village, DIT, playback, virtual production, and the broader video/data side. Your AV skills transfer, with the addition of understanding the film-set world (its departments, hierarchy, protocol, and rhythm) that this book provides. Combining your technical AV craft with film-set knowledge positions you to work in film and television production, a major and converging part of the industry. The set is a place where AV and film increasingly meet.

The video roles, and what each is responsible for

Video assist takes the camera's live picture and distributes it: to the director's monitor, to the DP, to the script supervisor, to clients, and to a recorder so takes can be played back immediately. On smaller shows it is one person with a cart; on large ones it is a team with wireless links and many destinations. In North America this work is usually covered by the sound and video local; elsewhere it sits with camera.

The video village is the physical result: the cluster of monitors, chairs, shade and comms where the people who are not operating the camera watch the take. It is built by video assist, and it is the most visible thing you will make, because the director and the client sit at it all day.

The DIT owns the picture as data: copying media off cards, verifying it, backing it up, often applying a look, and preparing what post gets. The loader handles the cards themselves on bigger crews. Playback plays content the camera photographs — screens in the scene, phones, projections — and sometimes reference material for the director.

On virtual production stages, the brain bar is the team running the LED volume and the real-time engine, and it draws directly on media server, LED and networking skills. Prompting, corporate shoots' teleprompter work, and on-set streaming are also routinely handed to whoever has AV skills.

Where each role sits in the chain of command

Video assist and the DIT work within the camera department and report to the DP, whichever local carries their card, although the director talks to them all day. Playback is usually camera or production, depending on the show. The brain bar reports to the virtual production supervisor, who works with the DP.

This matters when somebody asks you for something. A producer who wants the monitor moved, a client who wants a different feed, a director who wants a playback: do the small ones, and refer anything that changes the setup to your head of department. Nobody on a film set is annoyed by "let me check with the DP".

What these roles have in common

All of them are quiet, fast, invisible and continuous. You build before anybody needs you, you sit through takes ready for something to fail, you move when the camera moves, and you are the first person asked when a picture does not appear.

All of them also carry one irreversible risk each: a lost take, a lost card, a screen that flickered on camera, a prompter that stalled during a five-minute unbroken speech. Everything else on a set can be done again tomorrow. Those cannot, and it is why these jobs are checked twice.

The video and data roles

Who does what, who they answer to, and the one failure each role must never have.

On the job

A two-camera corporate shoot in an office. The production hires one person for "video", and that person is you. On the day you are running video assist for both cameras, building the small village the client sits at, playing a slide on a practical screen in two scenes, and running the prompter for the chief executive's piece to camera.

That is four of the roles in this chapter at once, which is normal on small shows and impossible on large ones. The way you survive it is the order: build the village first because the client needs it, prepare playback content before the day, and set the prompter during the lighting of the setup before it.

How to do it

1. Ask which roles you are covering — assist, village, playback, prompter, data.
2. Ask the DP where the village goes and how many monitors are needed.
3. Ask camera what the output is — SDI, wireless, frame rate, resolution.
4. Ask production what content must appear on camera, and get it early.
5. Ask the sound department for timecode if anything must be in sync.
6. Agree with the DIT who is recording takes and who is keeping them.
7. Set up so that one failure — a battery, a cable — never takes out everything at once.

What goes wrong

Practice it

Match the role to the failure it must never have.

Video Village and Video Assist

Video village is a signal flow problem with an audience. The camera's picture has to reach a set of monitors, look the same on all of them, be recorded so any take can be replayed within seconds, survive the camera moving, and run on power somebody else owns — while the people watching it are the director, the DP and the client.

Everything in this chapter is craft you already have from AV. What is new is where it plugs in and who is standing beside it.

What the village is for

The director watches the take here, because the operator is behind the camera and everybody else needs to see the frame. The script supervisor watches continuity and takes notes against it. The DP watches exposure and colour. On commercials, the agency and the client watch, sometimes from their own monitors, and sometimes remotely.

So the village has audiences with different needs: the director wants a clean, large, correctly graded image; the script supervisor wants to replay the last take; the client wants comfort, shade and a chair. Build for all three and you will be asked back.

The signal chain, end to end

The chain starts at the camera's output — usually SDI, sometimes more than one, at the show's resolution and frame rate. From there it reaches your cart by cable on a stage or by a wireless video link on the move. A distribution amplifier splits it to monitors and to a recorder. A LUT box or a monitor's own settings apply the DP's look, so what people watch matches what the camera is capturing.

Then the same discipline as any AV system: every monitor fed from the same chain, every cable labelled at both ends, a spare link ready, and enough battery and cable to move the whole thing in a company move. Wireless links need clean line of sight and a frequency that does not fight the sound department's radios or the location's Wi-Fi.

Record everything. A small recorder taking the same feed gives you instant playback of any take, which is what the director and the script supervisor will ask for several times a day. Label takes as you go, because "can we see take three of the last setup" is a question with a five-second answer if you have been disciplined and a two-minute one if you have not.

Building the village

Place it where the director can reach it in seconds from the camera, out of the shot, out of the light's path, and out of the route the crew walks. On location, that means shade, weather cover and hoods so the screens can be seen. Ask the AD before you settle: they know where the background walks and where the next setup goes.

Chairs, a table, headphones for sound, and a route for cable that nobody trips on. Gaffer tape on every cable crossing a walkway, and no cable across a doorway at all. Power from where electric tells you, not from the nearest wall socket, and batteries for anything that must survive a company move.

Playback of takes, and who asks for it

After a take, the director may ask to see it. That is your moment: cue the take, play it on the big monitor, stop at the right point. The script supervisor may ask for a specific take and specific timecode for continuity. The DP may want to compare two takes for exposure.

Keep a simple log of scene, setup and take against your recordings. It takes a second per take and it is the difference between being useful and holding up the day.

The village signal chain

Each stage, and what fails there.

Who watches, and what they need

Four audiences at one village.

On the job

An exterior day in a car park, bright sun, one camera on a gimbal moving around a vehicle. Cable is impossible, so the picture comes over a wireless link.

You build the village in the shade of a truck with hoods on the monitors, put the receiver high on a stand with line of sight to the camera, and run the recorder from the same distribution as the director's monitor. At the third setup, the camera goes behind the vehicle and the link drops.

Because you had a spare receiver on a second stand at the other end of the village, you switch to it in ten seconds and tell the AD the picture is back. The take is not lost, and nobody except the AD ever knows.

How to do it

1. Ask the DP how many monitors and where they want the village.
2. Ask the AD where you may put it, and where the background walks.
3. Get the camera output format and frame rate from the 1st AC.
4. Run the primary feed — cable where possible, wireless where not.
5. Split to monitors and to the recorder from one distribution point.
6. Match the look on every monitor, using the DP's LUT.
7. Tape every cable crossing a path, and none across a doorway.
8. Test the recorder by playing back a test take before the first real one.
9. Set up a spare link or a spare monitor path before you are asked for one.

What goes wrong

Practice it

Plan a village for a location day with no mains power.

Media, Data and the DIT

Everything the camera shoots exists, for a few hours, only on a card in somebody's hand. Losing it cannot be undone: the actors have gone, the light has changed, the location is released. This is why the DIT's job is built out of verification and redundancy rather than speed, and why its procedures never bend for a production that is running late.

An AV professional arrives with the right instincts — backups, checksums, labelled media — and needs the film workflow around them.

What the DIT actually does

The DIT receives media from the camera, copies it to more than one destination, verifies every copy against the original, and only then releases the card to be reused. They keep a record of what came from which camera and roll, they often apply the DP's look so the images post sees are the images the DP intended, and they prepare the material that goes to editorial.

On bigger shows a loader handles the cards physically, carrying them from the camera to the DIT cart and back, and the DIT stays with the data. On smaller ones one person does both, which is where mistakes happen if the discipline is not written down.

The offload, step by step

A card arrives with a physical indication that it is full and unloaded — different crews use different systems, but every crew has one, usually a red tag, a case position or a flipped card. Nothing is ever assumed about a card's state; it is read from the agreed signal.

The copy is made to at least two destinations, and each one is verified with a checksum, not by comparing file sizes or by trusting a progress bar. The copy software writes a report of what it copied and what it verified. Only when both copies are verified does the card go back into the shoot marked as empty.

The rule everyone uses is three copies, two kinds of storage, one of them somewhere else — which on a set usually means two drives on the cart and one that travels separately, or one that is shipped or uploaded at wrap. A drive travelling in the same vehicle as its backup is not a backup.

Looks, LUTs and what post receives

Cameras usually record a flat, low-contrast image that holds the most information. The DP's intended look is applied on top, as a LUT or a colour decision list, so the monitors show the picture as intended while the recording stays flat and recoverable.

The DIT carries those looks through: the same LUT on the village monitors, in the dailies, and as metadata for post, so the editor and the colourist see what the DP meant. When a video assist operator and a DIT apply different looks, the director asks why the picture changed, and the answer is always in that mismatch.

Chain of custody, and the words that go with it

Media has a chain of custody exactly like evidence: who had it, when, what was done to it, and where the copies are. A DIT can say at any moment where every frame shot today exists, on how many drives, and which of them have left the set.

As an AV person handling media anywhere near a set, adopt the same habits: never format a card because you believe it has been copied, never move a drive without telling the person responsible, and never let the last copy of anything travel alone.

A safe offload

The sequence that never changes, however late the day is running.

The three-two-one rule

The backup rule every media workflow uses, in its film form.

On the job

The day is running two hours late and a producer asks you to format a card so camera can keep shooting. The DIT is mid-offload of another card and the second copy has not finished.

The right answer is no, and the reason is worth saying once, calmly: the card cannot be reused until both copies are verified, and it will be ready in four minutes. The production finds another card, which is what spare media exists for.

Four minutes of waiting is an inconvenience. A formatted card that had not been backed up is a day of shooting gone, and it has ended careers.

How to do it

1. Learn the crew's signal for a full card and an empty one, and use only that.
2. Copy every card to at least two destinations before it is reused.
3. Verify each copy with checksums, not by size or by eye.
4. Keep the copy reports, and read them.
5. Log camera, roll, card and destination for every offload.
6. Keep one copy physically separate before the unit moves.
7. Never format a card yourself unless it is your responsibility and it is verified.

What goes wrong

Practice it

Answer as if you were asked on a busy set.

Playback, Prompting and Content on Camera

Some of the picture comes from you. A laptop screen in a scene, a phone showing a message, a television in a bar, a video wall behind a presenter, the words a chief executive reads: all of it is content the camera photographs, and all of it is the video department's problem.

On-camera content has one rule that separates it from every other AV job: the camera, not the eye, is the audience. A screen that looks perfect to you can be unusable in the frame.

Why screens misbehave on camera

A camera does not see continuously. It samples the world once per frame, for as long as its shutter is open. A display does not emit continuously either: it refreshes, and many displays flicker or scan in ways the eye smooths over. When those two rhythms do not agree, the frame shows a dark band rolling through the screen, a partial image, or a flicker that changes take to take.

The fix is to make them agree. The display's refresh rate has to relate cleanly to the camera's frame rate, and on serious work the playback is locked to the same reference as the camera — genlock — so every frame the camera takes catches a whole, settled image. On a 24 frame per second shoot, that means content and displays prepared and synchronised for 24 frames, which is where the phrase 24 frame playback comes from.

Ask three questions before any screen appears in a shot: what frame rate is the camera running, what shutter angle is it using, and can the display be locked or set to a refresh that matches? Then test on camera, in the frame, before the actors arrive.

Practical screens and the art department

A screen in a scene is a practical: a working prop. The art department supplies and dresses it, the camera department frames it, and you feed it. That means agreeing early on what the screen is, what it can accept, where its cable runs and how it is powered, because all of that has to be hidden.

The content itself comes from production, usually through the production designer or the graphics department, and it must be cleared: real logos, real brands and real people's data cannot simply be used. Get the final file early, at the right resolution and aspect ratio, and loop it or cue it exactly as the scene needs.

Running playback to a take

Playback is cued to the take, not to the clock. The AD's call sequence tells you when: at "roll sound" and "roll camera" you start your content so that by "action" it is in the state the scene needs. After "cut" you reset it, like everybody else, back to one.

Rehearse it. A scene where a phone rings at a line of dialogue needs your timing agreed with the actor and the AD, not improvised on take one. Write the cue down. If the content has to restart, know how long it takes and tell the AD, because that number sets how quickly the set can go again.

Teleprompter, and the presenter in front of it

Corporate and commercial shoots run on prompters: a screen below the lens reflected in glass so the speaker reads while looking down the barrel. The operator scrolls at the speaker's pace, not their own, and follows them when they go off script rather than racing ahead.

Set it up during the lighting of that setup: mount, glass, text size that the speaker can read from their distance, and a rehearsal so they can see it and you can learn their speed. Carry the script in a form you can edit — speakers change words on the day — and keep a paper copy for the moment the software fails during the one good take.

Before a screen appears in shot

Five questions, asked before the day, not during it.

What goes wrong on camera

Symptoms in the frame, and what they mean.

On the job

A drama scene in a control room with six practical monitors showing a security feed. The shoot is 24 frames per second with a 180 degree shutter.

Two days before, you get the monitors' make from the art department, find they can run at 48 hertz, and prepare the content as a 24 frame loop. On the day you feed all six from one playback machine, genlocked to the camera reference, and shoot a test frame before the actors arrive. No bands, no flicker.

The alternative — arriving on the day, plugging a laptop into six screens at whatever refresh they default to — is a morning lost while a DP tries to shutter around a rolling bar.

How to do it

1. Get the frame rate and shutter from the camera department.
2. Get the screen make, resolution and refresh from the art department.
3. Prepare content at the right resolution, aspect and frame rate.
4. Lock playback to the camera reference where the shoot allows it.
5. Shoot a test frame and look at it on the monitor before the cast arrive.
6. Agree the cue with the AD and rehearse it once.
7. Know and state your reset time.

What goes wrong

Practice it

A scene has a laptop screen in shot, shooting at 24 frames per second.

Virtual Production and the Volume

A virtual production stage is an LED wall the size of a set, showing a rendered world that moves correctly as the camera moves, so the background is photographed in camera rather than added afterwards. It is the place where film work and AV work have merged completely: the wall is an LED wall, the processors are LED processors, the signal is video over a network, and the timing is genlock and timecode.

If you have built an LED wall or run a media server, you already know more than half of this.

What a volume is made of

The wall is LED cabinets, often curved, sometimes with a ceiling. Behind it are LED processors mapping content to panels. The real-time engine renders the world, usually on several machines working together, and sends it to the wall. A camera tracking system reports exactly where the camera is, so the engine can render the world from the camera's point of view.

The part rendered correctly for the camera is the frustum — the cone the lens actually sees — while the rest of the wall shows a version good enough to light the scene and reflect in surfaces. Everything is locked together with genlock so the wall, the engine and the camera agree on time.

The brain bar

The brain bar is the team running all of it: engine operators, a systems or LED lead, a tracking specialist, and somebody owning content. They sit at a desk of machines beside the stage and work with the DP and the virtual production supervisor.

The AV skills that transfer directly are LED panels and processors, video over IP, media servers, networking, timing and colour. The film skills to add are the ones in this book: the calls, the department structure, and the discipline of not touching what is not yours while a hundred people wait.

What goes wrong on a volume

Moiré — the wall's pixel grid beating against the camera's sensor — is the classic problem, managed with distance, focus, lens choice and panel pitch. Scan lines and banding appear when the wall's refresh and the camera's shutter are not locked. Latency shows as the background lagging behind a camera move. Colour mismatch between the wall and the foreground lighting makes everything look wrong on camera.

All four are AV problems with film consequences. None of them is fixed by turning it off and on again, and all of them are worked through by the brain bar with the DP watching a monitor.

Where the jobs are

Volumes hire LED technicians, systems engineers, networking people, media server operators and content wranglers, and they hire them from AV rather than from film, because that is where the skills exist. It is the clearest route from a live events career into film work, and it is why LED video, media servers and networking are the skills to build before you look for volume work.

The parts of a volume

What each part does, and the AV craft it comes from.

Volume faults and where they come from

The four the DP will point at, and what each one really is.

On the job

Your first day on a volume as an LED technician. The wall is up, the engine is running, and the DP reports a shimmer on the wall in a wide shot on a long lens.

The brain bar works it as an AV problem: check that the wall refresh is locked to the camera, check the shutter, look at the distance and focus the shimmer appears at, and try the content at less fine detail in that region. The DP tries a different lens. Between you, the shimmer goes.

Nothing about that process is film-specific except the room it happens in and the fact that forty people are waiting while you do it.

How to do it

1. Learn the signal path from engine to processor to panel before anything else.
2. Find out what everything is genlocked to, and where that reference comes from.
3. Learn who owns content, who owns tracking and who owns the wall.
4. Never change a processor setting without the LED lead.
5. Watch the camera monitor, not the wall, when judging a problem.
6. Keep the calls of the set — a volume is still a set, with an AD running it.

What goes wrong

Practice it

Say which part of the volume each belongs to.

Sync, Power and the Signal Chain on Set

Two invisible systems hold a set together for anybody doing video work: the timing everything shares, and the power everything runs on. Both belong to other departments, both have rules, and both end days when they are taken for granted.

Timecode and why sound owns it

A film shoot records picture and sound separately, and they are matched afterwards by timecode: a clock, running at the show's frame rate, recorded alongside both. The production sound mixer generates it and the camera department jams its cameras to it — copying the running clock into each camera at the start of the day and again when it drifts.

Anything else that has to line up gets the same clock: a second camera, a recorder at the village, playback, a prompter that must match a take, the engine on a volume. If you need timecode, ask the sound department; do not invent your own.

The slate does the same job visually. When the second AC claps it, it gives an unmistakable frame and sound to align, which is why "marker" is called before action and why nobody walks between the slate and the lens.

Genlock, frame rate and the show format

Genlock is a shared reference that keeps devices in step frame by frame — cameras, switchers, playback and LED processors. Timecode says when; genlock keeps everything running together. Most single-camera drama does not need it; multi-camera, live comp, on-camera screens and volumes do.

The show format is the frame rate, resolution and colour space everything runs at, decided before the shoot. Ask it on day one and set everything you own to it: your recorder, your monitors, your playback, your prompter. A village running at the wrong frame rate produces stutter that people will blame on the camera.

Power on location

On a stage there is house power. On location there is a generator, and every circuit belongs to the electrical department. You ask the gaffer or best boy for power, you are given a circuit and a route, and you use that one. A video village drawing from a socket somebody else is using for a lamp is how a take is lost.

Take your own distribution — a short cable run to your cart with its own protection — and run on battery for anything that must survive a company move or a generator changeover. Label your plugs so electric can see at a glance what is yours.

The other rule is the one from every safety chapter: cable across a walkway goes in a ramp or under tape, never across a doorway, and never where a truck will drive. Weather cover for anything outdoors, and connections up off wet ground.

The chain, drawn once

Before the first setup, draw your own signal chain on one page: camera output, link, distribution, monitors, recorder, and where timecode and power come in. Pin it to your cart. When a picture disappears an hour into a busy day, you will not be reasoning from memory, and anybody standing in for you can follow it.

What each timing signal does

Three different clocks, often confused, each with an owner.

Power on a location day

Where a video department's power comes from, and the rules attached.

On the job

A two-camera interview day. You bring a recorder for the village and assume it will match the cameras.

At lunch the editor calls from the office: the recordings will not line up, because your recorder is running free instead of on the show's timecode, and it is at a different frame rate.

Ten minutes with the sound mixer fixes both: timecode jammed from their generator, frame rate set to the show format. The morning's recordings are still usable as reference, but the afternoon's are usable as material, which is the difference between a video assist who is trusted and one who is not.

How to do it

1. Ask the show format — frame rate, resolution, colour space — and set everything you own to it.
2. Ask sound for timecode and jam anything that records or plays back.
3. Ask camera whether genlock is in use, and what it is referenced to.
4. Ask electric for power, and take the circuit and route they give you.
5. Run battery for anything that must survive a move or a changeover.
6. Draw your signal chain on one page and pin it to the cart.
7. Re-jam timecode after lunch and whenever a device has been off.

What goes wrong

Practice it

Answer for a location day at 25 frames per second.

Safety on a Film Set

Film has a written safety culture that live events often lacks: a set of industry safety bulletins covering the specific hazards of production, read out in safety meetings, and referred to by name. The hazards are the familiar ones — electricity, height, vehicles, fatigue — plus four that belong to film: firearms, pyrotechnics and flame, stunts, and vehicles driven for camera.

Your part is to recognise them, stay outside the zones, and know that you may stop work.

The safety meeting and the bulletins

A safety meeting is held at the start of a day that has a significant hazard, and often at the start of every day. The AD runs it, the specialist explains their work, and the exclusion zones and signals are named. Attend it. Standing at the back of a safety meeting with your phone out is the surest way to be the person who walks into a zone later.

The industry's safety bulletins are written guidance, numbered by topic, covering firearms, pyrotechnics, working at height, electrical, vehicles, water, animals, cold and heat, and more. Productions distribute the relevant ones with the call sheet. Read the ones for the day you are on.

The four film hazards

Firearms, including replicas and blanks, are handled only by the armourer or property master, are never pointed at anybody, and have their own exclusion zone and briefing. Nobody else touches one, ever, for any reason.

Pyrotechnics and flame belong to the special effects supervisor, with a licence, a fire watch, extinguishers standing by and a countdown everybody hears. Stunts belong to the stunt coordinator, who owns the area during a stunt absolutely. Vehicles for camera — process trailers, camera cars, picture vehicles — are run by stunt and transport with a spotter, and nobody rides or reaches into a moving rig without being part of the plan.

For all four, your job is identical: attend the briefing, learn the zone and the signals, stay outside it, keep your cable out of it, and never improvise inside it.

The everyday hazards, in film form

Electrical: generators, distro, wet locations and long cable runs, all owned by electric. Height: lifts, ladders and rigging above the set, which are trained work. Fatigue: film days are long and turnarounds short, and the drive home is a real hazard measured in the industry's own statistics.

Hot work and fire: lamps, practicals and effects near drapes and scenery, with a fire watch when required. Trips: cable across walkways, in the dark, with people walking backwards carrying things. All of these are covered in Safety Awareness & Rigging Basics; on a film set they arrive faster and with more people around them.

Stopping work

Anybody on a film set may call to stop unsafe work, and no professional production will punish somebody for doing it. The words are simple and you do not need permission: say that you are stopping, say why, and say it to the AD.

Report injuries and near misses through the AD and the medic, on the day. It goes in the production report, which is the record that makes a hazard get fixed rather than repeated.

On the job

An exterior night with a stunt: a car arrives at speed and stops on a mark. The stunt coordinator holds a safety meeting at the top of the shot, names the zone, and says nobody stands in the run-off area.

Your second monitor is in the run-off area. You say so in the meeting, and it is moved before the rehearsal instead of being noticed during the take. The coordinator thanks you, which is not what a newcomer expects and is exactly what a good set does.

How to do it

1. Attend the safety meeting and listen to the specialist.
2. Learn the exclusion zone, the countdown and the signals.
3. Check whether any of your gear or cable is inside the zone, and move it before rehearsal.
4. Ask where you may stand during the take.
5. During the take, stay where you agreed and watch your own gear.
6. Report anything unsafe to the AD immediately, and stop work if it cannot wait.
7. Report injuries and near misses on the day, through the AD and the medic.

Working on a Film Set

What is left is how you actually get onto sets, and what keeps you being called back. Film hires through relationships, locals and reputation more than through applications, and the route in for an AV professional is usually through the work they can already do better than anybody standing there.

Bring your AV craft plus set knowledge, and you can contribute to film production.

Putting it together

Pulling it together, working on a film set means understanding the departments and hierarchy, following the protocol and etiquette, knowing the AV/video roles where you fit, and moving with the rhythm of the shooting day — combined with your technical AV skills. The AV professional who brings this understanding to a set can step into a video role (video village, DIT, playback, virtual production) and contribute professionally, fitting into the set's structure and culture. It is your AV craft plus film-set fluency that makes you effective in film production, which is an expanding opportunity for AV people.

Growing into film work

Growing into film and TV work means combining your AV skills with film-set experience — getting onto sets in a video or data role, learning the set world hands-on, and building the relationships that drive film hiring. The video/data side of film (video village, DIT, playback, virtual production) is where AV professionals most naturally enter, and from there you build set experience and reputation. As with all of the industry, film is relationship-driven, so professional conduct on every set is what builds a film career. This book has given you the orientation; real sets build the rest.

Film and television production is a major part of the industry and increasingly AV-driven, especially with virtual production and the growing video/data demands of modern shoots. For an AV professional, understanding the film set opens a whole domain of opportunity. Bring your technical craft, conduct yourself professionally on set, understand how a set works, and you can contribute to film and TV production — one more direction your AV skills can take you. The film set, once a separate world, is increasingly a place where AV professionals belong.

Try this. Imagine you're hired to run video village on a small shoot. Using this book, list what you'd need to understand about the set (hierarchy, protocol, rhythm) beyond just the technical setup, and why each matters.

How film crews are hired

Most film work comes from a phone call. A head of department needs somebody tomorrow, and they call the person they have worked with, or the person somebody they trust recommended. That is why conduct and reliability matter more than any qualification on a set, and why the first day of any job is a job interview for the next one.

In North America much of the work is union, through IATSE locals organised by craft and region — camera, sound and video, grips, electricians, editors — with their own entry routes, hours requirements and rosters. Elsewhere the structures differ, but the principle is the same: a local or a guild governs who works, and getting in takes days on non-union productions, contacts and persistence.

You will be hired as a day player for single days before you are hired for a whole show, paid at a day rate agreed in a deal memo before you start. Keep your own record of days worked, who you worked for and what you did; it becomes the résumé nobody asks you to write.

Routes in for an AV professional

The routes that actually work: video assist and playback on commercials and corporate shoots, where crews are small and AV skills are obvious; virtual production, where LED and media server people are in short supply; corporate and branded content, which shoots like film and hires like events; and rental houses and facilities who supply video gear to sets and send technicians with it.

Say yes to the small jobs. A one-day corporate shoot with a prompter and two monitors is a real set credit, and the people on it work on bigger ones next month.

What gets you asked back

The same things as anywhere, sharpened by the pace: be early, be ready before you are needed, be silent when it matters, never touch what is not yours, and never be the department that made the day late. Say clearly what you can and cannot do. Fix your own mistakes and say so.

And learn the room. A set rewards people who watch: who is stressed, what is about to be needed, which department is waiting on which. The video person who has the monitor already moved, the playback already cued and the prompter already set is the one whose phone rings next.

On the job

Eighteen months ago you were a live events technician who had never been on a set. You took a one-day corporate shoot running a prompter, because nobody else wanted a Saturday.

That producer called you again for a two-camera interview day, where you built a small village. The DP on that job recommended you to a commercial house, who needed video assist on a three-day product shoot. On that job you met an LED technician who told you a volume stage nearby was looking for systems people.

Nothing in that chain was an application. All of it was being early, being quiet, and doing exactly what you said you would do.

How to do it

1. Take the small jobs, including the awkward ones.
2. Ask what the show format, the roles and the gear are before you accept.
3. Get the deal memo before the first day.
4. Arrive early enough to be ready at crew call.
5. Learn the names and roles of the people you work beside, and write them down.
6. Leave the location as you found it, and thank the department you worked with.
7. Keep your own record of days, shows and contacts.
