Thank you, I got the alpha going. I just used chromakey to alpha out the white. Was that the right way to do it?
I was looking for a template that was 3 shapes, a square on the left with two stacked rectangles (or squares) on the right. I know it’s simple, but can I build that with Vegas (I suck at Photoshop)? Or can I search on the web for templates? What are they officially called, video masks?
