VirtualDub Sound Problem-Rather, Lack of Sound

Postby LordPhoenix » Sat Nov 30, 2002 5:20 am

When I use VDub to output an avi file, I can't get sound. And before you tell me to read the manual, I did, twice. Has anyone else every encountered this problem before? Can anyone help? Thanks!

What is your input audio/video codec?

Are you doing Direct Stream Copy?

What are you output video/audio codecs & settings?

Ok, I got it. I'm inputin divx fast and outputtin divx fast, I do this because it puts the size down quite a lot without losing any quality (well, maybe alittle bit). I tried direct stream and the other settin, forgot what it was...Not sure what I had the settings at, I read the manual and did what in instructed but still deosn't work. I'm fairly new to this stuff, so maybe its just in my stupidity I've done something wrong...Well, thanks.

K, gonna hijack this thread, cause I have the same problem, different reason.

I'm trying to slice up VOB files, so I create the .d2v and .avs files per usual, open them in VirtualDub, and try to clip out a 3 second clip. No sound. I also note that if I open the AVS in Premiere, no sound. Does AVIsynth not support sound (no reason it should in this business...:) ? Conversly, does anyone know a program when I can cut clips from VOBs other than VD? Assume the "just capture the footage from the DVD rather than Rip" option has been discarded...

Thanks!

..You're not meant to have sound. For sound, you have to either put it in with VDub, or use the AudioDub syntax in AVISynth, but you have to make a WAV audio file in DVD2AVI (Or make an AC3 and convert that to WAV with Besweet, whichever you prefer)

Well, thanks but I know how I can do it then, I'll output a wav file from the thingy I get all my footage from, then tie it all together. Thanks for the help. Later.

I wouldn't be recompressing DivX footage. That's just a bad idea :\

The idea is to only go through DivX once, not two or three times.

:\

Also I would look into using XviD something like that...

Humm...thanks for the help althought I'll still recompress it, its not a AMV, just somehting about tellatubys, that I'm gunna put up at my site as a joke. So it doesn't matter about the quality although it really doesn't take the quality down all that much. Humm but for actual projects and stuff like that I'll do it how you suggested..or whatever. Anyway, thanks.

There is no sound in a D2V file - it's a reference to the video stream inside it. If you want audio you'll need to demux the AC3 file, decompress it to wav, and cut from that. If you want your audio and video synced, you can make your D2V file and select an audio track from DVD2AVI's "Audio" dropdown menu and say "Decode" which will dump a WAV. Then in your AVS script say:

AudioDub(MPEG2Source("blah.d2v"),WAVSource("blah.wav"))

Thanks, (I think, but maybe not, I'm not sure and won't be in till I figure out what you said..) Although making a wav file from the video wont be hard at all cause I'm gettin my footage form psmplay and it out puts wav files as well as avi's so I'll be able to tie them together for a much smaller file size..I think.
