This is really annoying. I've heard a lot about how Apple have removed a lot of different codec uses including the most needed Quicktime RGB+Alpha one in After Effects. I can no longer import videos with an alpha channel into Premiere. I've tried ProRes 4444 but that didn't work either. All I get is "The importer reported a generic error."
I've tried restarting the project, restarting my computer, reinstalling premiere and so on. This is absolutely crucial to my business and must be fixed soon. Does anyone have a work around to this?
