UV Mapping - Virtual Sets
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". Any chance you could implement this to help make the virtual sets easier to use?
UV Mapping is a term I've heard used to map 2D images around 3D images but that doesn't seem to be what you're describing. Perhaps you mean corner pinning so a flat object can match the perspective of a source on a flat surface? Their angled screens for example?Reply

The flat surface solution is a simple use case. But we have all seen virtual sets with a studio that has a curved surface behind a presenter. To map onto the curve would require UV pinning.
Personally, I don't need that. But the people that make your virtual sets have indicated that they would prefer UV mapping. I'm just passing on the message. That would work for both simple flat surfaces, as well as more complex surfaces.
This was in a messenger chat... I was asking for assistance building an XLS that could be used - with input being the four (X,Y) co-ordinates of a TV, to calculate the centre point, and the 3 rotation values (X, Y, Z)... That will still require some tweaking of the zoom etc, but it will get 99% of the work done to get content behind virtual set elements - taking into account the angles required.

I am trying to do calculations for rotation X,Y,Z for inserts into the screens - Have you guys created an XLS file that does that, or are you just suggesting doing it by eye?
And the reply:
No, most systems we do it with uv maps so we are just waiting for telestream to implement this
I would be happy as an interim solution to get an XLS that will do the math for me - but a built in capability would be good in the long term.
Greg Kuhnert You can certainly make the feature request. Perhaps there haven't been requests for it yet (or at least not in significant numbers). Or perhaps ask them to contact us about that as it's possible they haven't.
