For no reason, in the beginning of February, film & TV player stopped playing mp4s.

Sorry if bring french contents here. I work in french most of time and it's my first language.

Because of this, my favourite video editor won't recognize mp4s anymore.

Compiling videos into compatible format but ...

it says unsupported video type.

This video editor was working great before this problem occurs.

Because of this, I can't submit my 3d cartoon to Newgrounds.
