Comment (by Cigaes):

 Can you extract and attach the subtitles track of your sample? It should
 be quite small enough to fit into the size limit.

 My guess is that you have overlapping ASS events. Matroska+ASS can handle
 it, but probably not MP4+mov_text, and there is nothing much you can do
 about it, any conversion will be lossy.

 {{{-fix_sub_duration}}} is for subtitles codecs that are terminated by an
 empty packet instead of having a duration. That is true for dvdsub (and
 possibly PGS) inside MPEG-TS, but never for anything inside Matroska.
