>>82775583The thing is this kind of three screen arrangement is indeed used IRL to shoot mixed media - e.g. you CGI the background and then have the real participants walk around on it.
But the camera position is supposed to be known and the displayed content warped properly so it appears seamlessly integrated from the camera's perspective.
I can only imagine the director of this is smirking about how avant garde they are filming a performance 'raw' but also in 3D or some shit
