Some ProRes flavors do not display correctly in QuickTime on M1 MacBookPro

On my brand new MacBook Pro running 12.0.1 Monterey, some flavors of ProRes 422 HQ and/or 4444 produce only BLACK images when opened in QuickTime Player (or inside Adobe After Effects or Premiere). I can hear the AAC soundtrack fine, but the video is blank. (RV Player from Shotgrid opens them fine.)

Older versions of MacOS where the files do open or import fine reveal that these are "Lavc58.18.1000 prores_ks" flavors with Trillions of Colors+, and I'm pretty sure they were originally generated/encoded by ffmpeg.

Hoping filing this report will somehow lead to the QuickTime team updating the next round of the Monterey OS or QuickTime components, and my M1 machine will soon be able to read what my older machine has no trouble with. (If there is somewhere else to submit this bug, someone please let me know.)

Thanks,

z

MacBook Pro 16″, macOS 12.0

You might want to check ffmpeg settings. See also:

Using any unauthorized implementation (such as the FFmpeg and derivative implementations) might lead to decoding errors, performance degradation, incompatibility, and instability."
