Problems with audio sync in Virtual Dub

[Rampager]

Hello.

When I'm going to encode something the sound always go wrong, it's syncing out. Therefor I've been trying to capture the sound separatley from Virtual Dub and then combine them in TmPeg.

But when I'm opening a video file in Virtual Dub I get this message:

"VirtualDub has detected an improper VBR audio encoding in the sourcce AVI file and will rewrite the audio header with standard CBR values during proccessing for better compatibility. This may introduce up to 22483 ms (different from different movies) of skew from the video stream. If this is unacceptable, decompress the "entire" audio stream to an uncompressed WAV file and recompress with a constant bitrate encoder, (bitrate: 130,1 +- 8.8kbps)"

What should I do. Please help me someone, I will be very happy then!

Capture the video and audio at the same time. Scan for junk frames, save the audio as a .wav, then encode the original video and audio in TMPGEnc.

Hi what i'v been doing is ignore the error and extract the wav then go to tempg and when you encode the film adjust the Audio Gap. I did show time and did it at -600 mil secs and it was bang on. I tryed to do collateral damage as that was way out to but deleated it before i used this method so i will have to get it again hope this helps....if anyone has done collateral damage and has worked the audio gap please post thanx..

colateral damage ...the audio gap is -6780 in tmpg i think you will find that this is spot on.....if downloaded from kazza from sharereactor hope this helps anyone....

I had the same problem with an episode of Enterprise I got of an IRC, it was in a AVI ( Divx ) I then seperated the audio into WAV file using VirtualDub & using TMPGenc I converted it into MPEG, worked great however I had same problem with Odyssey5 & that trick would not work, no matter how or how many times I tried it.

Everybody seems to have a problem getting the audio to sync with the video when converting from AVI to MPEG. If the audio syncs in the original AVI then use the decompress audio program that comes with Virtual Dub. I use it all the time if TMPGEnc won't accept the sound part of the AVI I'm encoding and it is brilliant. No messing - just decompress to _pcm and encode - easy.

Extract the audio:

Virtuladub > File > Open > (ignore VBR message) > Audio Tab > Compression > No compression > Audio Tab > Convertion > 44100 (if you are doing VCD) > File > Sav as Wav.

Use WAV as Audio source in TMPGE
