Your virtual set capability is missing an essential element. To get a video element to appear behind an alpha layer television, is harder to do than solve a rubix cube. The people at virtualsetworks advise “most systems we do it with uv maps so we are just waiting for telestream to implement this”.

There is another reason why this particular technique would be helpful. In addition to putting video on a TV screen, there is also reflections. UV mapping could also be used to map a reflection of a TV onto other surfaces that are not 100% flat within a virtual set.

Any chance you could implement this to help make the virtual sets easier to use?
