Audio out of sync second half but not a 2 part dvd

[donfrenchiano]

the dvd in question is disneys the scarecrow of romney marsh. it was a 3 part miniseries. i ripped it to disc with ifo mode of dvddecrypter which shows 1 whole 2 hour 30 min movie. after it is encoded with gordian knot the audio is fine for the first part but later on it is out of sync. should i try ripping in file mode and then trimming excess in dgindex? has anyone else had this problem

Open the IFO in PGCDemux and tick 'by VOB id'. Then check in the drop-down box to see if there's more than one VOB id. Maybe there are three, one for each episode. Then check to see if the length of the first is the same as the point where the audio begins to go out of synch (maybe the length of the first episode). Perhaps each VOB id corresponds to the length of each episode.

If so, then my guess is that the audio for each episode is shorter than is the video which causes each episode to get more out of synch. You might try using PDGDemux to get a VOB for each episode ('create a PGC VOB') and then feed the VOBs into AutoGK separately. That way you'll be encoding the episodes separately.

Either that or decrypt each episode separately to begin with by checking the chapter numbers that correspond to each episode.

When I've done something like that and I don't want to encode each episode separately I've opened up the AVI with VirtualDubMod and split it into the three episodes, re saving each as a separate AVI. The first AVI is generally synced okay. I'd then open the second and third AVIs with a media player such as media player classic and use the + & - keys to alter the audio delay until it's in sync. After making a note of the required delay I'd then open each with VirtualDubMod, set the appropriate delay and resave them as new AVIs. The final step would be to open the first AVI with VirtualDubMod, then append the synced version of the second episode to it, then the synced version of the third AVI, and then save the lot as one single AVI again which should contain all three episodes once more, this time with audio that's in sync.

ProjectX might be able to eliminate the sync issues. It's the the tool I always use when everything else fails, so far ProjectX fixed all DVDs I tried causing any audio or subtitle sync issue. It can demux video, audio and if enabled also vobsub subtitles, everything perfectly synced.

Thanks for that. Co-incidentally I just wasted a heap of time chopping up an AVI, adjusting the audio delay for each piece and putting it back together. I finally got the whole thing right but while I've got a problem file handy I'll give Project X a spin.

Thanks manono. selecting the title by VOB id in pgcdemux and then just renaming the final results into consecutive vobs allowed gordian knot the encode one single file with all audio in sync!
