virtualdubmpegII and audio synch problems

[Lileman]

I need help fixing audio/video sync issue with the resulting avi made by VdubmepgII. In the video the person starts speaking 8 seconds before he is supposed to.. How do i go about syncing this. Ive looked all over and it seems like a hard process. Im not oppose to this, i just need an explanation.I cant seem to fix this. I need this for a film i am making so any help would be appreciated.

Hi-

This is going to assume that you have a constant asynch, that the audio is off by the same amount all the way through:

Open the AVI in Media Player Classic. Right-click the screen and go Options->Filter->Audio Switcher->check the "audio time shift" box, and fill in an estimate of the amount of asynch. Hit "Apply" and test it out. Negative values are to make the audio play earlier. 1000 ms= 1 second. Resume playback. Adjust until you get it right. At that point you'll know how much the audio is out of synch and how much to set the delay in VDubMPEG2. Then open the AVI in VDubMPEG2, set the Video for Direct Stream Copy, go Streams->Stream List->Right-click the audio->Interleaving->Audio Skew Correction, and set the same delay as you found using MPC. OK your way out of there, go File->Save As, give it a new name, wait a minute or 2, and test it out.

When all done, either uncheck the box or set the audio time shift back to 0 in MPC.
