What Is a Sound Stage, and When Don't You Need One?

‘Sound stage’ is used loosely. Any large room with a cove gets called one in a listing. The term has a precise meaning, and knowing it saves two kinds of mistake: hiring a stage you did not need, and hiring a small studio for a job that needed the stage.

Scope is a small studio in Camberwell, not a sound stage, and we say so on the film studio hire page. This guide is about telling which one your treatment is asking for.

What a sound stage is

A sound stage is a purpose-built, soundproofed building for shooting sync-sound pictures. The name dates from the arrival of sound in the late 1920s, when the open stages of the silent era had to be enclosed so that dialogue could be recorded. The defining features have not changed much since:

• Soundproofing. Thick walls, isolated doors, silent air handling and no windows, so the only sound on the floor is the sound the production makes.
• Scale. Stages are measured in thousands or tens of thousands of square feet, with ceilings high enough to build two-storey sets and fly lamps above them. Several usually share one lot, with workshops, offices and dressing rooms attached.
• A lighting grid or gantry. A permanent steel structure over the floor, often with walkways, from which lamps are rigged by a crew working above the set rather than from stands on the floor.
• Infrastructure built for all of it: heavy power distribution, rated rigging points, an elephant door for vehicles and large set pieces, a cyc or green screen on at least one wall, and often a tank or a flying rig.

What a stage costs a production — in scale and crew

The day rate is only the first line. A stage makes everything around it bigger.

• Crew. Rigging from a grid means rigging crew and electricians working at height, usually on a prelight day before the shoot proper, and a big set adds riggers, standby carpenters and painters.
• Time. A set that fills a stage takes days to build and a day to strike. Those are paid stage days with a paid crew in them, before a frame is shot.
• Transport. Big lamps, heavy stands, distribution, scaffolding and flats arrive on trucks, not in a van, and each truck has a driver and a loading window.
• Location and overheads. Most stages sit on a lot outside the city, which adds travel or accommodation for a London crew, plus facilities fees, security and catering for a larger call.

The jobs that genuinely need a stage

• Dialogue scenes on large interior sets where the sound has to be clean and the set has to be built — a two-storey house, a period room with the ceiling in shot.
• Sets that need to stand for weeks: a series shooting several episodes on the same build.
• Anything rigged from above at scale — a large overhead soft source over a wide set, wire work, flying rigs.
• Large-format virtual production and LED volume work, which needs the dark, the height and the power.
• Water, fire, vehicles in motion, crowd scenes, and other work where the stage’s safety infrastructure is the point.

The much longer list that does not

Most of what gets made for screens is on this list.

• Commercials at the scale most brands actually shoot: a product, a presenter or a performer on a cove or a small dressed set. The producer’s checklist for a studio commercial is written for exactly this.
• Interviews, talking heads and documentary sit-downs, which want a quiet room and control of the light, not a hangar.
• Music videos, where the performance is lit for the look and the sound is a playback track.
• Short films’ interiors. A flat, a bedroom, a café corner or an office is a two- or three-wall set that fits a 1,200 sq ft room — see shooting a short film in a studio.
• Content days: a run of social, product and presenter set-ups shot back to back in one room.
• Corporate and training video, e-commerce and fashion, podcasts with video, castings and tests.

What a small stage offers instead

A small studio gives up the grid and the scale, and offers the things a smaller production actually spends its day fighting for. At Scope:

• Studio A — 1,200 sq ft with a white drive-in infinity cove, full blackout curtains and ground-level load-in through the roller door from the yard. There is no lighting grid; everything rigs from stands, and the ceiling height is on request rather than guessed, so ask with your tallest piece in mind.
• Studio A is not sound treated. For clean sync sound, Studio B is a sound-treated room within a room with a colour-washable cyclorama, blackout and its own edit and playback area — the room for dialogue and interviews.
• A podcast room and a music studio with a treated vocal booth for voice, ADR and audio under the same roof — see sound for video in a studio.
• A whole small building to take over. The whole-building buyout from £1,500 a day gives a production Studio A, Studio B, the podcast room, the music studio, the workshop, the kitchen, the dressing room and the parking, with nobody else on site — a lot in miniature. It excludes the DJ room.

Rates: Studio A is £160 for two hours, £320 for a half day and £620 for a full day; Studio B is £120, £220 and £420. Set-up and pack-down sit inside the booked time. In every room but the DJ room, lights are charged separately from the room rate — please enquire about our lights and we will quote for what your shoot needs.

The question is never ‘is this studio big enough?’ in the abstract. It is ‘what does this treatment need the room to do?’ — and most treatments need a dark, quiet, well-lit room with a door the kit fits through.

How to tell from the treatment

Read the treatment or the shot list with five questions beside it:

• Is dialogue recorded sync, and how much of it? Sync dialogue wants a treated room — Studio B, or a stage. Playback and voiceover do not care.
• What is the tallest thing in the shot, and does anything hang above it? Rigging overhead at scale needs a grid. Rigging from the floor does not — but ask the studio for its ceiling height before you book.
• How long does the set stand? Hours or a day fits a booking; weeks fits a stage, or a buyout of consecutive days.
• How many people are on the call? A unit that needs a production office, costume and make-up working at once needs a building, not a room.
• What has to come through the door? A car, a large flat or a built unit needs ground-level access. Studio A is drive-in; a stage has an elephant door.

If the answers point at a stage, hire one — it will cost less than discovering the need on the day. If they do not, a small studio will do the job for a fraction of the crew and the hours. How to budget a studio shoot in London picks up from here, and the film production glossary has the terms.
