Working with Video Files

I want to use Audacity to process the audio in an MP4 video file. I can import the audio just fine, but when I export it as an M4A, only the audio is exported, not the video. A video file is not much good without the pictures :laughing:

This would be a nice feature if the capability does not already exist.

Audacity is an audio editing program. You need to use a video editing program to add the audio track back to the video.
