Title: Lossless audio compression with VirtualDub?
Post by: Digisurfer on 2005-09-05 05:43:50
Hey all, quick question. I Just entered the world of video capture recently and am wondering if there are any lossless audio codecs that work with VirtualDub for capture. Thanks!

Nope, PCM is your only choice.

Thanks, figured as much. How about transcoding the PCM to (for example) Wavpack, and then replacing the PCM audio track in the video file with it? I know there are Directshow filters for the playback of Wavpack and FLAC (haven't checked the others) so playing the final file shouldn't be a problem.

You can do that (FLAC, Wavpack or TTA) if you don't mind using Matroska. With AVI no such thing is possible.

Great, thanks for the heads up. Learning as I go, hehe.

One more quick question. If PCM is my only choice, why are there compression options, including MP3? I can even install the Directshow filters that come with LAME and use those in VirtualDub as well. Not trying to be a pain, only trying to understand. Thanks again!

I meant to say: If you want to have lossless audio, PCM is your only choice.

Using MP3 is of course possible (watch out to not use ABR/VBR modes, as they wouldn't work in VirtualDub also), but that wouldn't be lossless.

From here: http://forum.videohelp.com/threads/343407-...l=1#post2188956 (http://forum.videohelp.com/threads/343407-FLAC-in-Virtualdub?p=2188956&viewfull=1#post2188956)

Now you can import it.
First remux the flac file to mkv (using mkvmerge) then import with the Matroska input plugin: http://forums.virtualdub.org/index.php?act...f=7&t=19488 (http://forums.virtualdub.org/index.php?act=ST&f=7&t=19488)
(and Use Audio Direct Stream Copy to generate AVI even if you can't hear it in vdub)
