I am not sure if this is the right forum to post this. But I have seen some live theatre performances (plays and musicals) that instead of using tradicional backgrounds (usually painted on fabric) they project a video.
The video is not completely still usually but is has some minor movement, reflecting for e.g. a landscape, a sky, etc.
I believe that the bottom part of the composition is almost dark, so the projection is not seen on actors' body. Is this right?
I would like to know if you believe this technique is difficult for doing it in a medium-size theater (let's say a stage about 30feet wide and 25 feet tall)?
What program and or thecnique is used to design the background? After effects? Premiere? (I regularly use the Adobe Suite)
What kind of projector?
