Comment (by MarkZV):

 It appears that the cause of the problem is that {{{-avoid_negative_ts}}}
 defaults to 0 for MP4, and 1 for M4V.  The reason for that is unknown.  It
 seems that this should be 0 for both, since the edit list already handles
 negative timestamps by mapping time 0 to a media time greater than 0.
