Alpha Channels from Windows to Mac
Interesting issue. I had a friend render out some videos for me with Alpha channels. He uses a windows machine and I use a Mac. I output a few of the files and he output the rest from his Windows version of AE. When I got the files back I place them in my document and added a background. The files I output worked fine. The windows files had a rule around the alpha path that I couldn’t get rid of. We both used the same output settings. Pro Res 4444 with alpha.
Has anyone else had this experience?

Did your friend render with a straight matte? Sounds like pre-multiplied matte was used which would cause what you describe.

I will check with him. Thanks
