Audio Out of Sync

[pthrussell]

Ok, I have a DivX file of an X-Files episode. I encode it with Xing MPEG Encoder, getting the sound from an external WAV file so that I don't get a whole ton of noise instead. First I try NTSC, then PAL. Both files have similar problems. The NTSC one has the sound a second or two ahead of the actions. The PAL one has the sound half a second slow. I read that you're supposed to use VirtualDub to fix this. So I go into VirtualDub. I can set the new frame rate to match the sound. But, it's only .001 of a frame ahead or something like that. Could this be my problem? If it is, then what do I do to get it back into the MPEG without saving to an AVI and re-encoding, making it look like crud? And also, wouldn't it just get out of sync again?

Please Help!

Tmepg has a feature where you can move the audio track +/- m.seconds to match the video. However, the offset needed has to be contant and not change throughout the video.

skittleson is right about that. but i would do this: using bbmpeg i would remux the sound with an increase/decrease of a delay for a few mins and then test the output file and see how it went. I had a vid out of sync with sound and adding a delay of 444 to the audio made it purrrrrfect.

The weird thing is, the original file is in sync...

cant you just open up the video file and then save it as mpeg
