Comment (by PumaD):

 Replying to [comment:2 MasterQuestionable]:
 > ͏    MKVToolNix..?\\
 > ͏    https://gitlab.com/mbunkus/mkvtoolnix#1-introduction
 Yes, that one. Sorry, I shouldn't have assumed everyone to be familiar
 with it.

 > ͏    Sure it's MP4?\\
 Your implication being that MKVToolNix can only read MKV and not MP4?
 That's not the case. In can only create MKV but read a very wide variety
 of input formats.

 > ͏    What's your [https://mkvtoolnix.download/doc/mkvmerge.html
 `mkvmerge`] command? (if indeed MP4 input)
 I used the GUI, but that only constructs a command line. A simple
 `mkvmerge --output slightly-damaged-refuses-to-play.mkv slightly-damaged-
 refuses-to-play.mp4` works.

 > ͏    FFmpeg much relies the filename extension: when
 [https://ffmpeg.org/ffmpeg.html#Main-options ͏"-f"] not specified.
 Good to know, I wasn't aware of that. However, you already confirmed in
 your other comment that it's indeed MP4.
