I've seen this error message posted several times but none seem to have a solution that works for me.
I have a large Quicktime ProRes 4444 Alpha file that won't import into Premier or Adobe products. It does playback in QT but in Pr it give me the message "We were unable to open the file on disk. File contains more than one image descriptor."
I'm on an M1 Mac and I exported a clip with an alpha using Compressor. What does it mean when it says the file contains more than one image descriptor?
