Adding new audio to mpeg/avi video files

Hello.
I am looking for a simple program who can add new audio to a mpeg/avi video file.
Let's say i have a video recorded from TV. The sound is horrible, so i want to take that audio from my original cd and add this .wav file to the video, vithout rconvert the video file.
I know that Adobe Audition knows that, but only with avi files.
Thanx a lot.

Well for mpg's you can use something like TMPGEnc's MPEG tools and for avi VirtualDubMod or AVIMuxGUI. For the mpg, you probably want to convert to mp2 (via say twolame) first and say mp3 (via lame) for the avi.

 

Ok celtic_d, but i think TMPEnc is renconding the video file. it's that right? Adobe audition for example, it's only apply the new audio on the video file. not reencoding the video and adding the new audio file.
it's TMPCEnc doing the same thing?

There is no encoding involved with multiplexing.

 

Done with tmpceng.
Now i try do do the same thing on an avi file, with AVI-Mux GUI
if you know pls give a me some short indications.
i am mixing the new audio but the old one is still there
thanx

 

Seems to be a bug. You can untick streams, but it doesn't do anything. Guess someone should tell alexnoe.
