AVI has unknown Audio... and won't edit properly

[modem]

I have a AVI file I downloaded. It's from the Stargate SG-1 TV series, episode 1, season 1. The file name is 1x01 Children of the gods. The AVI file is great, crystal clear quality, great playback etc. Well inside of that are some scenes that I prefer to have edited out for younger children or sensitive adults viewing.

I followed my standard proceedure for editing this, opening VirtualDub editing, saving etc. Well when I did that with this movie/divx file the output was great video quality. But there was no sound. I proceeded to then check the file information inside of VDub but for the audio it said unknown format. I then started the process of removing the audio into an uncompressed WAV file. That didn't work and gave me the error that the output format is not the same as the input.

Can anyone help me with this? My goal is to edit out about 3 seconds of scenes with working audio.

I would guess the divx has Ac3 audio (does vdub say 5 channels under audio info by any chance?). If so, extract from the avi using vdub direct stream copy. Rename output file as *.ac3. Convert from AC3 to wav using Headac3he (you may need to run it through Ac3fix first to fix errors caused by vdub extraction). The re-mux with the original avi using vdub. Then edit away!

Hope this helps

I checked and it only has 2 channel audio, but I did follow your instructions anyway. I renamed the output file to AC3 and then used headache to covert it to wave. I opened the 1.2GB wave file and it played fine.

The question is, how do I re-mux with Virtual Dub??

Start Virtual dub, open you avi file.
Video->Direct stream copy
Audio->wav audio (select your new wav file)
File->save avi (save out a new version of the avi such as movie2.avi)

All done!

Just to let you know I did all of that and it seemed to work perfectly. I could and did edit out what I wanted removed. The only downside is after re-muxing the avi file size was 700mb prior, and is now 1.05GB. Is there anyway to shrink that?

When you select the wav file, also select mp3 compression. Or, if you want abr/vbr mp3, create this first and then interleave with the video using a modified version of Virtualdub called Nandub.
