I am aware of the solution with -pix_fmt yuv420p as stated here but that encodes it at 4:2:0. I would like the encode to be a 4:2:2 and changing to -pix_fmt yuv422p doesn't work. I've tried different containers with out lack. What definitely works is 'prores' but I don't need such a high bitrate video.

For context, I create timelapses from photos and I would like to be able to use Quick Look or Quick Time for playback.

I use mediainfo to check the video's attributes.

    I don't believe that QuickTime can play 4:2:2 H.264. But I don't have QT so I can't try. – llogan Oct 11 '19 at 20:19
  • It seems that you pointed me to the right direction. QuickTime [doesn't](https://forums.creativecow.net/docs/forums/post.php?forumid=20&postid=864735&univpostid=864735&pview=t) support 4:2:2 h264. Apple's rationale is that if you want 4:2:2 and 4:4:4 you should use ProRes. Thank you. – thanosam Oct 11 '19 at 21:19

To answer my own question. As @llogan pointed QuickTime doesn't support h264 4:2:2. The only option is with 4:2:0 as stated here.
