Converting .AVIs with VBR-MP3 Audio

Simply use NanDub (or VirtualDubMod) to save the audio stream as an Uncompressed PCM (WAV) file as follows:
Load your original .AVI into NanDub
Set "Video" to "Direct Stream Copy"
Set "Audio" to "Full Processing Mode"
From the "Audio" dropdown menu, select "Compression" - and choose "No compression(PCM)"
From the "File" dropdown menu, select "Save WAV" (Enter a new filename with a ".WAV" extender).Click on "OK"
Then set "Video" to "Direct Stream Copying"
Then save the .AVI as a silent .AVI (set "Audio" to "No audio" after you've saved the WAV file).

Then close NanDub and restart it
Set "Audio" to "No audio"
Load your silent .AVI
Set "Video" to "Direct Stream Copying"
Under "Audio" click on "WAV Audio" and load your .WAV
Set "Audio" to "Full Processing Mode"
From the "Audio" dropdown menu, select "Compression" and choose the appropriate .MP3 settings. Click on "OK"
From the "File" dropdown menu, select "Save as AVI" and save your file with a new filename.

Does it really make sense to split the avi in a videofile with no sound and an uncompressed wav-file? I think it should work the same if you open the original avi in NanDub, use video->directstreamcopy and audio->fullprocessing, select the MP3-codec and save it. As NanDub internaly converts the old sound-format to wav and passes it to the new audio-codec, it should be exactely the same result as your method.

You are 100% correct!

As I've said many times before, the day that I have nothing new to learn will be the day they bury me ;>}
