Are you looking for a green screen studio in Brussels capable of handling ambitious productions? The green screen fascinates as much as it intimidates. Behind this green canvas lie almost limitless creative possibilities: sets that are physically impossible to build, custom-branded environments, visual effects that are accessible to any company. But there are also technical pitfalls that can turn an ambitious shoot into a post-production nightmare.
This guide explains how chroma key works, why studio size is crucial, what adjustable LED lighting allows, and how StreamBox has positioned itself as the reference for premium green screen productions in Belgium – with 30 years’ experience in audiovisual production and 7 professional sets in a 600 m² complex in Rhode-Saint-Genèse, 15 minutes from the center of Brussels.
How does chroma key work?
Chroma key consists of filming a subject in front of a background of a uniform color – usually green – then replacing this color with any visual element in post-production. The result: your presenter finds himself or herself in a virtual set, an animated desktop in your brand’s colors, or your software’s interface.
Green is the standard because digital sensors are more sensitive to it: it represents 50% of the pixels on a CMOS sensor, compared with 25% for red and the same for blue, which facilitates clean cropping. Green doesn’t match human skin tones either, so you can avoid unintentional transparencies on your speakers.
Mistakes to avoid: green or finely patterned clothing, poorly lit backgrounds with cast shadows, insufficient distance between subject and background, green reflections on light-colored hair. At StreamBox, our engineer checks the overlay in real time before the first shot, and shows you the final result on a monitoring screen.
Studio fond vert Brussels: why 60 m² changes everything
Most green screen studios in Belgium offer 20 to 30 m², enough for a single static presenter in bust shot. As your production becomes more ambitious, these limits become concrete constraints.
The basic rule of chroma key: the subject must be at least 1.5 to 2 meters from the background to avoid green reflections. The camera should be 3 to 4 meters from the subject for an American shot. On 25 m², your freedom is very limited.
With 60 m² of cyclorama space, StreamBox offers :
- Up to 4 or 5 operators simultaneously in the plan, with no risk of overflow
- All available angles, from close-up to wide shot
- Physical sets combined with green backgrounds (furniture, brand accessories)
- Impossible camera movements in a confined space
- Control room, monitor and prompter all in the same space for live streaming
This green-field studio in Brussels is part of a 600 m² complex comprising 7 distinct studios, each with a unique ambience, designed for companies, agencies and demanding content creators.
Adjustable LED ceiling lighting: the real differentiator
A successful green background requires two seemingly contradictory things: a uniformly lit background to facilitate keying, and creative scene lighting on the subject to give depth to the image. Most studios manage this with fixed, unadjustable sources.
At StreamBox, the LED ceiling lighting system is fully adjustable zone by zone in intensity, hue and direction. In practice: a cold, uncluttered corporate production in the morning, warm, dynamic YouTube content in the afternoon, in the same studio with a green background in Brussels, without reconfiguring a single light source. For live streaming, lighting effects can even be animated in real time.
30 years of expertise: why StreamBox is the reference in Belgium
Choosing a green screen studio means more than simply reserving a space. It means entrusting your production to a technical team capable of anticipating every problem before it costs time and money.
The StreamBox team has 30 years’ experience in audiovisual production, in 3 countries. Our engineers master the main compositing software (DaVinci Resolve, Adobe Premiere, After Effects) and validate chroma key keying in real time before each shot. Our Sony Cinemaline and Burano 8K cameras – the same equipment used in high-end cinema productions – guarantee sharp, precise images, with perfect depth of field for compositing.

Frequently asked questions about the green background studio in Brussels
How big is the StreamBox green screen studio?
The StreamBox cyclorama measures 60 m² – the largest available in Belgium for professional productions. It is part of a 600 m² complex comprising 7 separate stages in Rhode-Saint-Genèse, 15 minutes from Brussels.
Should you bring your own virtual set for a green screen session?
No, but you can. The StreamBox team creates virtual sets tailored to your graphic charter. If you already have your assets (After Effects files, 3D sets, motion design), we integrate them directly. Overlay verification is carried out in real time before the first shot.
Can you combine green screen and podcast video in the same session?
Yes, it’s one of StreamBox’s most popular formats. Record your podcast with a green background to integrate dynamic graphics, animated statistics or a thematic backdrop behind your speakers, without significantly extending the session length.
What’s the difference between a cyclorama and a classic green background?
A cyclorama is a continuous background with no visible angle between wall and floor. Unlike a hanging flat background, it eliminates basic shadows and facilitates inlays with sets that include a floor. StreamBox features a cyclorama painted in calibrated matte paint, optimized for digital keying.
Does StreamBox offer post-production after green screen shooting?
Yes, StreamBox provides complete support from A to Z: editorial strategy, script writing, studio shooting, full post-production (chroma key compositing, editing, color grading, subtitling, cutting into short excerpts for social networks) and delivery on Frame.io. No step is subcontracted.
How long does a green screen shooting session last?
A typical session lasts between 2 and 4 hours for a standard format (interview, testimonial, product presentation). More ambitious productions (live streaming, multi-stakeholder, events) can extend to a full day. StreamBox offers half-day and full-day bookings.
Is the green background studio accessible from Louvain, Liège or Namur?
Yes, the StreamBox studio is located in Rhode-Saint-Genèse: Leuven ±35 min, Namur ±55 min, Liège ±1h05, Ghent ±45 min, Antwerp ±55 min. Parking available nearby.

StreamBox uses Sony Cinemaline and Sony Burano 8K cameras – the same cinema-quality equipment used in high-end productions. Coupled with a zone-by-zone adjustable LED overhead lighting system, they guarantee a sharp image with perfect depth of field for chroma key compositing.
Is the green screen studio available for live streaming in real time?
