Xvid to DVD - Problem with audio synch

[emtfdny]

Hello,
I'm having a problem in converting 8Mile screener from xvid to DVD. The video comes out awesome with CCE doing the encoding. But when I load virtualdub and load the file to strip out the audio and it says :

" Virtualdub has detected an improper VBR audio encoding in the source AVI and will rewrite the audio header with standard CBR values during processing for better compatibility. This may introduce up to 10473 ms of skew from the video stream, If this is unacceptable, decompress the *entire* audio to a uncompressed wav file and recompress with a constant bitrate encoder . (129.7 _ 12.3 kbps)"

When select full processing mode and select save WAV I have no problems.

I get the problems after I have encoded the WAV to AC3 and author the movie to DVD. The first 5-10 minutes play perfectly in synch. But it loses synch after that.

Can someone help in correcting this problem please. Thanks all.

Please don't get me wrong, but i believe this has nothing to do with xvid.

I have made lots of convertions from xvid-dvd, and almost all went well.
I had some problems too, but were always in the audio part, like you are having.
But xvid ins't the one to blame here.

For what i could see, you are doing everything right (extracting the audio to WAV and then converting it to AC3.) Maybe is the way you are converting the WAV to AC3. Did you follow the guide for that?
Or maybe the authoring software you are using that is creating the problems.
I always use Maestro, and it gave me no problems. The audio dificulties i had were because in some movies i had "not regular format" audio sources.

But we are both risking a strike from the MOD's, because this thread probably belongs in the dvd section, or audio section.

Hehehe :)

Hi, iago. I am always around, not as much as old times, but i keep following xvid development.

As you know, i am more into dvd backuping now, but one of this days i will make a encode using the latest xvid buid, and compare it with some old encode from an older build, to see the improvements.

I am sure i will be amazed. ;)
