I'm wondering if anyone on these boards can give a recommendation as to the software/techniques that would be best for compositing multiple video layers. The project idea involves multiple (3 or 4, maybe up to 6 or so) shots that would have the exact same background, lighting and camera alignment but featuring people doing different things (though not necessarily interacting).
It's a relatively simple idea that I'd imagine there's a good piece of compositing software for. Ideally the software could automatically determine the consistent background and combine the shots at least semi-automatically. While I know a fair amount about 3D graphics, I'm not too knowledgeable about compositing. Hopefully someone can shed some light on the kind of software/workflow this project would require.
