QuickTime Player cannot open 'iCloud synchronization file' format videos on Mac
I have a bunch of videos that I've accessed before on my Mac and now I cannot. What can I do so I can view them?

Where are the movies stored? Can you copy them to your home folder without errors? What codecs do the movies have (H.264, H.265, HEVC, VP9, AV1 etc video, AAC, Vorbis, Opus etc audio -- you can check the details with apps like MediaInfo or Invisor)?
