Hi there ! I got that XviD clip that i want to convert to SVCD.
When i load it to Vdub i got the VBR msg.
So i decompress the wav and then load it as WAV audio in Vdub and try again.
Nothing ,still audio goes earlier.
I checked the clip for video errors and it have no bad frames at all.
Any sugestions?

The problem is that my source XviD clip is ok ,it plays without any loose of audio sync.
It happens when i try to decompress the wav and then load it to Vdub as WAV audio and Save the AVI.
When i save the avi i got audio goes earlier.

You won't listen, will you? If you audio is before the video, you have audio leading video phenomena. If the audio lead is constant throughout your video, use Gold Wave or some other audio encoder to add silence at the beginning of your audio file equal to the amout the audio leads the video.

make sure the audio and video have the same fps.

also, i was killing my brain trying to figure out how to convert a pal avi to ntsc svcd, because everytime i previewed it using media player, the audio and video wasn't in synch.

i found that using powerdvd (or use one of those programs specifically dvd playback) is the best for playing mpeg files, and when i used it to preview my svcd, the audio and video was synchronized.

i burnt it and played it on my dvd player, and i did the conversion rigth after all.

Load the clip into VirtualDub:

1> Audio -> Full Processing Mode
2> Audio -> Conversion...
3> Convert it to 48000Hz or 44100Hz (if it's already one of these, leave it).
4> File -> Save WAV...

You now have a separate (and huge) .WAV file to work with. Now fire up TMPGEnc 2.57, and in the wizard select your output format (Super Video-CD NTSC, NTSC-Film, or PAL). Click Next.

On the next page, select the clip you want to convert by clicking the "Browse..." button. Also select the WAV file you created in VirtualDub (as I described above) "Audio File" field provided (click the "Browse..." button next to it).


Click "Next" twice.

TMPGEnc will now give you a file size, and probably warn you that it won't fit on a standard SVCD. Ignore that, you can split it later, also using TMPGEnc (if you need help with that, check out the EDIT link and find the article about cutting using TMPGEnc).

What this does is joins the video source from the clip you have, with the WAV file you created into an MPEG2 clip.

There shouldn't be any audio sync problems at this point. If there are, refer to one of the many howto's on this site. Now that you have a separate WAV file, it'll make all of those tutorials MUCH easier.

The problem you're having is related directly to the method you're trying to use. From what I'm reading, you have audio sync in the original AVI, then you try to create a new AVI (which conforms to SVCD standards) and you're losing audio sync. Don't even bother converting an AVI to another AVI. Skip that altogether. Go straight from AVI + WAV to MPEG2 (which is what I've described above).

The audio has to be in a separate file when you combine it with the original video clip into the final product (an SVCD compliant MPEG2 file).
