AVI audio editing

[grumblybear]

I recently had some problems with an XviD AVI that had some unnecessary sound in the beginning which caused the entire file to be desynced.
I extraced the audio using GoldWave and cut the unnecessary audio out, but now how do I get this WAV file back "into" the AVI file?
Any help would be greatly appreciated.
Thanks!

You could always load the avi into Virtual Dub, then select your new wav as the audio source. Then select "direct source" and save it.

Okay I've got it all loaded up in VirtualDub and I tell it to save as AVI and I'm noting the file size as it's saving and it got to 3% and was already almost 5gb.
Why on earth is the AVI file so huge? Do I need to be doing some sort of compression I'm unaware of here? It's already in XviD format to begin with.

Make sure when you save it, to select "Direct Stream Copy"; I'm assuming you have it set to "Full Processing Mode" and uncompressed AVI. You don't need to recompress the video. Also, you might want to compress your audio too, a wav file will probably make it bigger than the original file was; I'm assuming that the original audio was a compressed format, perhaps mp2, mp3 or ac3?

Okay yeah I figured out the direct stream setting and it worked fine.
I did notice that the size of my movie is pretty much doubled now as you said it probably would be.
I really don't have a problem with it being that big, but is it easy to compress the audio to save size? Will VirtualDub do that?

Yes, you can compress to mp3 again using virtualdub. Just choose audio->compression and choose mp3. If you don't see any mp3 in the list install the lame mp3 (the acm).
