Comment (by Thomas):

 Sorry about the misunderstanding.
 Actually, this is the `prores_ks` encoding (4444 w/alpha) that is not
 correct, on all platforms.

 Flickering only occurs when playing the video on a Mac M2 though, using
 native players such as Quicktime, iMovie, etc.

 To reproduce:
  - encode a prores 4444 w/alpha video on any platform
  - play the video on a Mac M2 using Quicktime
