SVCD to DVD synch problems

[ShinyCDMan]

I'm converting some SVCD's to DVD, using the procedure given in the guide on Doom9, to produce an audio and video stream, with TMPGEnc and BeSweet (converting to MP2 etc.).

I'm then using DVD2AVI to convert the video stream to a .d2v file, so that I can then use TMPGEnc to merge the audio and video and encode into DVD compatible MPEG (I want to re-encode as I don't want any incompatibility problems with certain stand-alone DVD players).

The first time I did this it worked fine. But the last two times I've tried, the audio is out of synch in the final MPEG file while the original SVCD isn't! The only reason for this might be that I was doing some CPU intensive stuff in the background while I was encoding on the last two occasions.

Can anyone shed any light on this please?

Thanks,
Shiny

Doing tasks in the background will have no effect on audio sync. This is an issue only when capturing video. Your TMPGenc settings may be the culprit. You should verify if your SVCD is telecined ( www.lukesvideo.com ), and use the FORCE FILM option in DVD2AVI if your video IS telecined. Set your FRAME RATE setting in TMPGenc (Video tab) to 23.976 fps (internally 29.97 fps), and set your 'Encode Mode' to: 3:2 pulldown when playback). Note that the 23.976 fps (internally 29.97) option may not be available until you select 3:2 pulldown when playback for your Encode Mode.

If the audio sync is only a tiny bit off by the end of the video (say by a few seconds), then it's more likely that you have a few corrupt frames. In this case, you will need to use an audio editor to stretch, or shrink your audio output length to match your video length.
