Video walls aren't very suitable for this use case actually.
The Mandalorian has very specific prebaked imagery to do what it does where latency isn't a big deal. It also uses post production to clean up.
With the kind of volume space that the BBC have, and the frame rates and sweeping camera moves, they likely can't make use of current LED walls.
They don't have the offline resources to clean up the seams in the wall panels, and they probably can't afford the latency of the walls (with walls you need much lower latency than green screen since there's no temporal room to compensate for rendering latency)
- texec 5y agoVideo walls are suitable and are used. There are no seams between the panels and realtime rendering is fast enough for moving cameras. All camera movements are tracked, a virtual camera at the exact same position renders the image which is then shown on the LED wall. The image outside of the panels will be masked with a seamless transition (biggest obstacle here is video wall brightness vs. studio lights). Delays are adjusted for. You can see how this works in a very small set here: https://www.youtube.com/watch?v=mhmYawxWfjE https://www.youtube.com/watch?v=mhmYawxWfjE And here you can see how the image moves when the camera moves: https://www.youtube.com/watch?v=6koVH1vmLp4 https://www.youtube.com/watch?v=6koVH1vmLp4 The combination of the technologies is product of the last 2-3 years, but it is already used around the world and a major benefit is that there is no additional post production needed.
