Comment (by Cigaes):

 That is not true. Decoding from Matroska never requires
 {{{-fix_sub_duration}}}.

 Complex ASS can not be converted to mov_text, that is not a bug, that is a
 limitation of the format.

 {{{-fix_sub_duration}}} may make it seem to work, but it is only hiding
 the problems, not solving anything.
