Robotic Cameramen

A feature that is likely to recur.

But I want to focus on something specific about that idea, if you have a camera system, that could be fully actuated, and fast; would it be possible to scan an area completely in 3D with multiple cameras and a good use of thinking software running on fast computers, thereby replacing green screens completely, because you could just replace the backdrop in a camera generated 3D image?

I think yes, in the holographic age, yes.
