Some info on LED wall technology:

• I recently heard about LED wall technology through this Twitter thread, about The upcoming Bourne Stuntacular at Universal uses a giant LED wall as background, and it’s synchronized perfectly with stunt actors and props in the foreground. The result is a cinema quality production that’s playing out in front of viewers eyes.
• This is also the same way that Star Wars Mandalorian was shot. ILM recently showcased how dramatically this changed the production process. Unreal Engine also showcased LED walls in use in this Youtube video.
• The impact of LED wall technology has the potential to make complex production techniques more accessible. This will dramatically impact the financial structure of big budget filmmaking.
