What to look for before you book a green screen studio
Not all green screen studios deliver the same results. Here's how to tell the difference before shoot day.
A green screen shoot looks straightforward on paper. In practice, the quality of your key depends entirely on the studio environment — the lighting system, the cove condition, the power supply and how well the space is configured for the kind of production you're running. This guide covers the five things worth checking before you book a green screen studio in London, and what good answers actually look like.
The difference between a pre-lit green screen and a blank studio is a full day of rigging time.
Floor area tells you how big the studio is. Cove width tells you what you can actually shoot.
Most studios described as green screen facilities are simply studios with a green painted wall or a hanging chroma cloth. They require you to bring, rig and configure your own lighting before a single frame is shot — a significant cost in crew hours before the production day has properly started.
When assessing a pre-lit studio, confirm what lighting units are in use, whether the system covers the full shooting area evenly, and whether coverage is consistent enough to deliver a clean key without hot spots or fall-off at the edges. A well-specified system should be able to tell you exactly what units are rigged and how the coverage is configured.
A pre-lit green screen removes a full day of rigging before your shoot has started.
Drive-In Access — When You Need It and What to Confirm
Green screen shoots involving vehicles or large props need floor-level access, not a service lift.
Not every green screen shoot requires drive-in access — a presenter piece or small product shoot doesn't need a vehicle entrance. But productions involving cars, large props or oversized set builds do, and confirming this before booking is essential.
The measurement that matters is clearance height, not just whether drive-in access exists. A studio that describes itself as having vehicle access without specifying the clearance height may have a restriction that rules out the vehicle or equipment you need. Confirm the clearance height in feet before committing to a booking.

The Cove — Why a Green Screen Studio with an Infinity Cove Gives You More Options
A U-shaped cove extends the seamless background from the screen to the floor — removing the horizon line from the frame.
A flat green screen covers the background behind your subject. An infinity cove extends that seamless background down to the floor in a continuous curve — eliminating the horizon line that would otherwise appear in wide shots or low-angle frames.
For productions shooting at floor level, with low camera angles, or with vehicles that need to appear composited into a scene, the cove is what makes the shot work cleanly in post. Without it, the join between the vertical screen and the studio floor becomes a problem that has to be managed in post production rather than solved on set.
A cove removes the horizon line. Useful for any shot where the camera drops below waist height.
Power Supply — The Spec That Separates Production Studios from Hire Rooms
A green screen lighting system draws significant power. The studio needs the infrastructure to support it.
A pre-lit green screen system running multiple LED units simultaneously draws more power than a standard domestic or light commercial supply can handle. Studios built genuinely for production have the power infrastructure to support a full lighting system without tripping breakers or sharing circuits.
The key figures to ask for are total amperage and whether three-phase supply is accessible. Three-phase matters for larger productions running multiple heavy lighting rigs — it distributes load more efficiently and supports equipment that requires it natively. If a studio can't tell you the amperage clearly, treat that as a warning sign.

Production Facilities — What a Full Green Screen Shoot Day Actually Needs
A studio that works on paper but not on shoot day is a logistics problem from the moment the crew arrives.
Green screen productions often involve larger crews and more complex setups than a standard stills shoot. Before booking, confirm: are make-up and wardrobe rooms within the hire or shared with other productions? Is there a production office for shoot management? Is parking free and on-site? Is catering available without bringing in external suppliers?
These aren't luxury additions. On a full production day with a large crew, they're the logistics that keep everything running on schedule. A studio that can't answer these questions clearly is worth approaching with caution.
The facilities that seem like extras are often the ones that make or break a shoot day.
