Where's my sound?

[KCMagoo]

I've been trying for two days to get the sound to play on the avi i'm converting to svcd in TMPGEng. The video comes out fine.I've tried virutual dub to convert the audio to 44.1 wav format and using that as the audio track and that didn't help. Also, when I start Vitural dub and load the file, i get a popup screen that says:

"VirtualDub has detected an improper VBR audio encoding in the sound AVI file and will rewrite the audio header with standard CBR values during processing for beter compatibility..." Does this ring a bell with anyone? Could it be ac3? This is making me so mad...

The avi info is:

512x384, 23.976 fps
Decompressor: DivX MPEG-4 Low-Motion
audio sampling rate" 48000hz
compression: MPEG Layer-3 Codec (professional)

Dose the AVI not have sound to it, or is it just the MPG comming from TMPGEnc? I had a similar problem with TMPGEnc stripping the sound from the AVI when it encoded it, so i just opened up the orignal AVI file and exported the WAV, then multiplexed them with bbMPEG. It sounds like you are tryind to do what I did (?) and not having luck... Mayby you could explain in more details what your problem is.

The avi plays the sound just fine. How I tried first was just using the original avi file in TMPG as the video source and then extracted the wav with virutual dub with plugged that into tmpg as the audio and then encoded it. I'm confused with the mulitplexing...did I miss an important step somewhere? What's the deal with bbMPEG? Do I have to run it through there? If anyone knows of a good guide on bbmpeg or mulitplexing just send me the link, I'd appreciate it.

KC,

ave you tried to extract the soundfile in full processing mode?
If not, do the following:

Load the AVI file, click on the AUDIO tab of VirtualDub,choose Full Processing Mode, Click on the AUDIO tab again and choose Conversion
Select the 44.100 Hz in the Sampling rate section and click OK.
Now try to save the WAV file.

If that ain't working, shoot me!!!!!

VBR encoded audio is one of the few things virtualdub seems to have difficulty with. Save the audio out using direct stream copy. Vdub will give the file a .wav extension but in reality it will be encoded exactly as it was in the avi (probably VBR MP3). Then use BeSweet or Headac3he to convert the audio to uncompressed wav, converting to 44.1khz sampling rate at the same time if you wish.

Hope this helps.
