    Audio Sync Correction

    A question about Audio Gap/Sync correction in DVD Author 2.0. I've fiddled around with it a bit, but it doesn't seem to do much when I take a look at the preview. If the audio is ahead of the video, I want to make the gap correction negative, yes (e.g. -200ms)? Is there some trick to getting it just right? I've been working on this one project for ages, it seems, and can't seem to get it right.

      actually if the audio is AHEAD of the video, setting it back (-) does the trick. as for a sure fire method, you won't find one. experience only. i can get it in one or two tries, just encode a section of dialogue, not the whole file

        So negative is best, then? And as for encoding a bit of dialogue I'm using DVD Author _after_ I encode with TPMGEnc, so seemingly the only way to test the audio is after burning the DVD. Am I missing an intermediate step here?

          usually when setting audio delay, positive values push the audio back (or add silence). does tmpgenc do something different?

            it obviously must

            for TMPGEnc look at it this way:

            A ----------------
            B ---------

            A is audio, B is video, if A is ahead you want it BACK (-). that's how i visualize it, that's how it works with TMPGEnc.
