It might help to know the origin of this file. Even better: to allow access to it via whatever file-sharing service the kids use nowadays.

Per e621:supported filetype:

VP9 with Opus for audio preferred, VP8 and Vorbis supported. Matroska container (.mkv) not supported.

Should be YUV420 8bit, audio either mono or stereo and 48KHz/44.1KHz, shouldn't be anamorphic. Files other than this are subject for deletion as broken/corrupted.

You'll need to convert it somehow. I'm not personally sure of the best way to convert it.
