My investigations into audio sync issue

[DVDFabUser56]

How far are you roughly percentage wise are your over 50% done or less?

The complexity of the job is crazy. This is just one component of a complete re-write of the entire Mobile engine. Please be patient.

At the moment i'm just waiting for the sync engine to be rewritten but the length of time it is taking is crazy.

I'm still using 'dvd to mobile', but I'm verifying each conversion now. It affects about 25% of my movies.

Please tell me what exact setting are you using. Please try 2-pass and in Settings, under "Conversion" set memory for "max" not auto. Try it with known problematic title and let me know. And turn off any background processes, especially AV and FW. You can unplug it from web while processing, if you concern about hackers getting into your machine while you converting

The problem is that with any dvd that you convert in DVD to Mobile around the 90 minute mark the audio gets progressivley (it gets worser) out of sync towards the end of a movie, this has been most frustrating with the second pirates of the caribbean film.

Got a PM from Fengtao yesterday. Told me to be patient, a re-write is in progress and a beta will be released over the next few weeks. Same as before. I know it will get fixed but the length of time has been frustrating especially given other updates to the program have been coming with the usual regularity. I assume it is a big deal with this change they are making.

Hey guys, does anyone know the latest information regarding the audio sync issues because this problem has been around for too long and needs to be fixed because it has basically rendered the program unusable, and also has anyone heard anything from Ting recently because I sent him that private message nearly 3 weeks ago and sent him another one last wednesday and have had no reply, thanks

I'm sorry, but 11 pages of this thread later I do not remember what your problem was. Can you give me a quick remainder what you was converting to what? and what version of Fab you were using? Thank you.

My worst one is Mission to Mars, by the end of the movie it's so out of sink people talk with out moving their lips (kinda funny). Just converted the movie Penelope and it's fine go figure.

Hey guys, I sent a private messeage to Ting (The person that people say is trying to fix the sync problems) about the audio that gets progressivley worse near the end of a movie that you convert in DVD to Mobile and this was his reply:

Hi,

The problem has still exist in current version, but we upgrade the mobile engine, and rewrite the sync-engine, current in the last step of this, and hope can get one beta version for this, but there are not very accurate time for this, about in one or two weeks, hope this can fix your problem.

thanks.

Hey, anyone hear anything new from Ting about the progress on this? I know he said it might be 2-3 weeks, but since that was a week ago maybe he has a better idea of when a fix will be coming?

I tried the latest beta just for kicks and still get the problem where audio gets progressively more and more out of sync in the converted video. In my case the DVD is The Warriors (1979). The problem isn't terrible, but definitely noticeable by the end of the film. I've checked the actual disc playback and a DVD to hard drive rip and they're both fine, so it's the conversion (in my case to mkv with h.264) that's going bad.

I apologize for mentioning specific software. I intentionally didn't mention specific "alternative encoding software" for that purpose. I figured mentioning the program I did mention was okay since it was just a demultiplexer. Either way, if it is infringing please edit my post since I can no longer edit it myself.

Audio delay means that the sound track starts at a different point in time as the video track. A negative amount would mean that the audio track starts before the video (ever so slightly).

The audio tended to get more out of sync near the end of the movie. When I first encoded Airheads it was WAY out of sync at the end of the movie, however, I re-encoded it with DVDFab and it was just slightly out of sync. I just noticed ________ showing an audio delay and was just curious if perhaps that might be part of the issue. I could be wrong though. I will say though that encoding the movie with alternative encoding programs that utilize ________ to demux the movie first do not have any audio sync issues on these movies.

(I'm quoting this because you're about to get wrist slapped for mentioning other software on the forum. I didn't want to lose the jest of the answer in case a moderator deletes the post)
