I have two versions of the same video. One video is an MP4 video. The video quality is really good, but the sound is terrible. Then I have an AVI file that has a pretty decent audio to it, but the video isn't quite as good. Not bad, but the other video just blows it away. What I've been trying to find out is how to take out the bad audio file from the MP4 file with the audio from not as good visual quality AVI file. I converted the AVI file into an MP3 and have it as the audio, but I just can't get the audio to the MP4 Video...I also read somewhere about using WAVE format audio, but the bigger problem is finding a program that works. I've tried MPEG Streamclip, Graphedit, and a list of other programs, but none of them will work for what I'm wanting. I'm wanting to keep the same exact video quality as is, and windows movie maker lowered the quality down quite noticeably, which was my first attempt. I'll even add the info given from a program I found called MediaInfo. It would be great to figure this out so I could know how to in the future.

Come on, guys! I was expecting some know-how on this! I've been doing all I can for 3 days straight trying to get this working and decided maybe someone on this site would help. I think my respect for this site has gone down hill now...
womble mpeg video wizard dvd. Put your mp4 onto the timeline drag the second audio track into the audio timeline. Next on the mp4 file disable the audio (otherwise you have 2 audios on the finish file). This is a easy way of doing it, it will allow you to easily move the audio track so it lines up with the video.
Also avidemux is a free way of doing it, it handles mp4 and will let use a different audio track.
