Using the programs: Goldwave and ffmpeggui, i've been able to figure out how to extract the audio from the video and flip the channels correctly. See image below



But how do you exactly put them (video & audio) back together using Virtualdub??

Can someone please help me with a small tutorial? PM me or leave a response. Thanks in advance!

I was just fooling around in Goldwave to find the option for reversing channels. I know about the mp2. .ac3


OH, and.. TMPGEnc on encodes MPGS, not AVI's..

So I guess you have two avi files and two ac3 files, because of the fact that it's a 2CD rip. This guide is for VirtualDubMod but should be the same for the normal VirtualDub. Same goes for NanDub (I think)

Open VDub
File -> Open video file.

Go to Video and select Direct stream copy since you don't want to re-encode the movie. This is a simple muxing job.

Go to Streams -> Stream list.
Add -> add your ac3 file.
Click OK and go back to File

Select Save as, type in a filename and save.
Done. Now do the same for CD2.


Edit:
Async issues can be fixed via opening the avi, again set to direct stream copy. Go back to your stream list. Right click on the stream, select interleaving. Go to the area that says "audio skew correction".

Positive values are needed when the sound plays early and vice versa.

I tried searching around and couldn't find anything definitive/helpful. I can flip the audio in Goldwave, but I can't save the result as an AC3 file. Is there a good editor/utility that I can use (besides Sound Forge) to do the same thing? Or should I create the WAV file (or files if I need the channels to be in separate WAV files) and then convert it back to AC3?

This is the first time I've done any sound editing, so any help will be great.

To add to my last post, I figured out that I can encode the wav file back into AC3 using the FFMPEG previously mentioned. Would I lose any sound quality doing the conversion to WAV then back to AC3?

Thanks all!
