I feel like I have come across a weird event where on Adobe CS6, Premiere and After Effects, I was able to export an Animation Codec with RGB+Alpha and then convert it in Quicktime that would come out as a Pro Res 4444. I did this to cut down the space it would take up on my hard drive.
The great thing is that the Alpha would still carry over even after converting it from an Animation codec. But now for some reason, in Adobe CC, this will not work at all. I have gone back and forth between them trying to recreate but I am not getting the same outcome.
CC still looks like it carries the Alpha when I open it in Quicktime but when I bring it into Premiere, there is no Alpha. And the Interpret footage option does not work because Alpha is all greyed out.
Now I'm not sure if anyone else has come across this issue and figured out a solution, but I am just looking to save space as Animation codecs can be huge files.
