I think I found the problem…and perhaps a bug!
What I did was create a new project in which I had my logo pop up from the bottom, then some bars slide in from the right.
I rendered that out as a QT file as Animation and 32 BPP Color and 100% quality.
Brought it into a project and it worked great with alpha channel!
So, I decided that I wanted to have the logo and bars slide in, then reverse and go out after a few seconds.
So, I created a new project, brought in the QT file, CTRL dragged it to create a copy, placed it next to the original, then reversed it.
Then rendered it out…and BAM…there’s the problem.
For some reason I can’t get SV 12 to alpha channel a clip that has a reversed video clip.
Is there a way to do what I want?
