How do i make a movie maker file compatible with Audacity? And then how would I turn in back to an mp4

As far as I know, Audacity is audio editor, and movie maker produces (mp4) are video files.

If you want to edit the sound track of the video - export it as an MP3 or WAV, edit with Audacity, then put it back into the video. If you have these .MP4 files from somewhere else, there are other tools that will let you split and merge video files.
