I'm needing to add an alpha mask to multiple individual webcams to create a unique border. The broadcast will use the merge transition to move, scale, and crop these webcam panels around each other depending on how many are visible at a time. The thing is when I crop the webcams it is also cropping the alpha mask border, which is fine, but I don't have control over moving the mask in relation to the crop.

TLDR

Is there any solutions available to move an input WITHIN it's key/fill mask or are there other masking solutions that might have more control over the input being masked?

Do you by chance know if the merge transition would work between virtual sets? To explain further, I'm needing webcams in a certain position, size, and cropping in one scene then the ability to merge to another scene where those same webcams are moved and sized differently. With the transition taking place by smoothly sliding the assets around rather than have a fade.

I apologize, I was purely asking as someone unfamiliar with virtual sets, UV maps, and XML, assuming you might have relevant knowledge.



I've accomplished the effect outside of virtual sets of course, this was purely in regards to if the same functionality would occur between multiple virtual sets.




Thank you for your input! I'll dive into learning UV maps and XML.
