I have encoded two towers avi into 2 mpeg files ready to burn to VCD. Unfortunately the sound is a about 1 second ahead of what you see. Normally if my avis have a delay i use nandub to resave avi with a delay on the sound. Is there a program similar to nandub but for mpeg files failing that any other suggestions guys ?

Hi there,

I assume this must be an avi that you made from your original dvd as a way of playing on your laptop, ahem

So..

since you have an mpeg stream, get hold of a copy of womble mpeg2vcr, demux the mpeg into m2v and mp2, (or AC3 the latest version can handle both), streams then remux them using the audio sync slider to fix the problem. This assumes that the sync problem is constant, if it starts in sync then drifts things may be a little more convoluted..

If the sync changes, load the mpeg and check the total run time, then demux the mpeg and get the audio, convert to a wav file, (for mpg audio sound use winamp with disk writer plugin for AC3 best to use something like besweet), pull this into soundforge or similar and time convert it to run to the same length as the video, now get it back into mpeg audio/ac3 format and remux. :P

I imagine there are other ways to do this and hopefully you have a constant sync issue so can use the first solution. If the sync drifts and its an AC3 audio track I'm not sure of the best way to resync it and maintain multi track (5.1) dolby digital

OOOOPS

Well that will teach me, I didnt read you where dealing with mpeg1 for VCD. That makes life simpler.

You can use the mpeg1vcr download from womble which is a damn site cheaper and since you are using mpeg1 audio you may not even need to do that. Virtualdum can, I believe, handle mpeg1 video so you may be able to use the tools in there to resync. If not you can use mpeg1vcr from womble as I mentioned above.

Anyone out there know how best to do this using freeware tools ?

Sorry to be a noob I just need a few pointers. I open mepg file in virtual dub , go to interleaving and set audio correction to +250ms , then this is where im stumped , i dont want to save as an avi but there is no option to save as mpeg ?!

Many Thanks
