Green-screen broadcast studio
Eurosport wanted a new green-screen broadcast studio designed and built end to end. A green-screen studio looks deceptively simple from the outside, green wall, lights, camera, but the quality of the final chroma key (the process that replaces the green with a digital background) is determined by decisions made before a single light goes up: the structure of the studio, the exact green paint, and the lighting plan.
We took the project from architecture to commissioning. Before any build, we produced a 3D pre-visualisation render so Eurosport could see the structure, the lighting positions and the final look in context. Once approved, the install ran straight through.
The work split across three parallel tracks:
- Studio structure, designed for clean keying, with the right depth and the right falloff away from the green wall to avoid spill onto the talent.
- Surfaces, specialist green paint applied to spec, the kind that holds saturation evenly under broadcast lighting.
- Lighting plan, developed with directors of photography and gaffers we work with regularly on chroma-key productions. The fixtures and positions are chosen to light the talent cleanly without contaminating the green wall.
- vMix chain (the broadcast software stack) commissioned alongside the studio so it was ready for production on day one.
The studio is now in regular use for Eurosport's chroma-key productions.
