Can't find compatible movie format types listed anywhere

This is hopefully a quick and easy question.
I tried to look in the manual for the most recent version and all it has is 7 pages saying “What do you want to do?”

I just need to know if MP4 is acceptable as a file format for videos, or if there is one that PsychoPy works better/best with. Sometimes it’s picky on media file types.

I can’t seem to find anything except “PsychoPy supports a number of formats” then a list of a few on the movie component part of the how to stuff.

That doesn’t really help me, and the manual is empty on the site.
I haven’t made the videos yet, but I’d like to save myself work on the backend and just save them in the ideal format from the get go so I don’t have to do anything extra to fix it or make them work later.

Thanks in advance.

Does this page help?
