YES, this animation plays in all of my Windows media players, including
Irfanview. AND, it also plays in Firefox's 'preview'. Great work! Thanks for
taking the time to dig down into your settings for ffmpeg; very much
appreciated.

For this animation, my VLC Media Player does not report the particular 'chroma
subsampling' scheme that you used... but that seems to be its usual behavior
when encountering the 'typical' 4:2:0. So I guess the switch from 4:4:4 to 4:2:0
has solved the problem. That is interesting news! :-)
