Thank you Andrew! Thank you for clarifying about the QuickTime animation file. You suggested that I could roll back my Adobe products and I found confirmation in this blog post: Install a previous version of any Creative Cloud application I don't know if this will help anyone else, but I ended up using Compressor on Mac to change my QuickTime files to ProRes 4444. Luckily, there were only two files that I needed to convert, but they were used over 150 times in my After Effects file. By the way, I use After Effects in Windows and I edit in Final Cut Pro on Mac (I know, weird). I will have to use a previous version of Media Encoder on Windows, as you suggested, next time. Some of my older files have tons of legacy QuickTime files that I will need to convert. Thanks again! ... View more
