Comment (by brama):

 I investigated some more. The commit mentioned above fixes 1 video, but
 breaks another. I have now found the real culprit, and that is commit

     Another aspect ratio fix try. This leaves the setdar addition at the
 end (preferred by people).

 Later on, a new commit actually fixes the issue:

 But this commit is 100% reversed in commit
 d6c858658f2cd5cabbfecc008503c30951256fdd, because "it breaks fate" (?).

 So looks like the aspect ratio fix attempt is buggy.
