No sound on my SVCD, help :(

[shaman]

hey guys.

I have this AVI movie and the plan was to save the WAV file in Virtual Dub, converting the AVI to MPEG in TMPGEnc and then burning the MPEG in Nero, as this has worked with AVI's before.

The picture/video came out brilliantly but here was NO sound AT ALL. What happened was, when I went to get the WAV by using Virtual dub, it gave me a message that said

VBR AUDIO STREAM DETECTED


Virtual Dub has detected an improper VBR audio encoding in the source AVI file and will rewrite the audio header with standard CBR values druing processing for better compatibility. This may introduce up to 44981 ms of skew from the video sream. If this is unacceptable decompress the entire audio stream to and uncompressed WAV file and recompress with a constant bit rate encoder. (bitrate : 163.7 +/- 38.6 kbps)


what is that all about?

So then I went along with it, and hit OK (the only button to choose) and went and saved the WAV. Then I go into TMPGEnc and choose to convert the AVI using the source as the video file and the WAV from Virtual dub that I got as the audio file....then burned the MPEG in Nero and there is no sound....I have used this process for AVI's before and it worked, what gives? what can I do?

vdub doesn't handle vbr very well.
use nandub or VirtualDubmod.

Try this. D/L avi2vcd and use decompress.exe (look for it seperatly if you want) you will get a file called "filename pcm.avi" Go to TMPEG use the original avi for the video and use the pcm.avi for the audio. You can also sometimes get away with just using TMPEG using only the original avi. If the avi is a large file size, say 600megs I usually have no problems. Best explatation I can give you for it cuz I'm not a vid guru but have played enough to know when it should work. Personally I have more luck just useing decompress and TMPEG and staying away from Vdub.

The error you got in Vdub means that it is seeing the audio out of sync with the video and will create an avi with X amount of miliseconds of mismatch. It can be minimal or several seconds.
