full proccessing or direct stream in virtualdub?

[thecrock]

In virtualdubmod, if i want to save as a wave file should i have it set to full processing.
I have demuxed to a wav file before-but what difference will full processing have on the file?

If the stream is already a wav file then you can demux in direct mode. If you need to change the encoding then you have to use full processing mode.

In other wording - Direct stream just saves out the audio in whatever format it was found in the AVI (but gives it a .wav extension) - When using Full Processing, Vdub will decode and depending on selected output format even encode it.

Thanks for the replies.

Ok, just to get this straight.
What if my audio stream is mp3 for instance, will virtualdub just save that as mp3 with a wav extension if i don't have full stream processing enabled?

[mats.hogberg]

Yes. And even add some wav headers to the file.

Thanks fellas, I am just saving the audio to wav with pull processing on.
Will post back tommorow after encoding, again.

I generally just use direct stream in VirtualDub when extracting audio - then process it into whatever I want it to be with a dedicated audio tool (which, depends on audio format). Somehow, I've come to not fully trust VDub for audio work.

No joy, i saved the wave file from virtualdub with full processing enabled but the audio is still going out of sync.

[mats.hogberg]

Out of sync with what? (OK, the video, I get that, but after you do what with the wav and the AVI video?)

I could've sworn there was a guide to fixing VBR audio with Virtualdub and Goldwave but I couldn't find it so I made one up myself.

Exellent guide, thanks.One thing, in the guide you use lame to compress the .wav audio, do you have to compress the audio, can it not be left as .wav uncompressed?
