Terminator 2 extreme edition audio sync problem

[cogd115]

Hi, I was wondering if anyone here has had the same problem that I am having, namely audio-video out of sync. If so, how did you sync the audio to the video? The Xvid video looks great, and the AC3 sounds great, as well. Only if I can sync them! :) I will appreciate all the help and thanks in advance.

hi,
well it would help if you gave us a little more infos, maybe a log file or two :)

- what program did you use
- was it the R1 or R2 version (the R1 version got some seamless branching in it...

cheers

did some searching on this topic and i am having trouble finding the solution to this specific DVD. it is obvious to me that the seemless branching is causing some of the confusion which is resulting in audio sync issues...

i have tried ripping full disk mode using the latest DVDFab, then encoding using AutoGK from there, i tried both versions of the movie, the regular and extended, both resulted in odd audio sync issues.

i also tried passing the normal version from the Full Disk rip through DVD2One into a Movie Only output, then encoding from there with pretty much the same results.

the audio sync is an odd one, if it were a constant sync issue i would just play around with interleaving like i usually do in VirtualDubMod, but the amount of off sync changes drastically at a specific part of the movie, its not a slow sync change, its sudden... having said this, the movie is never in sync.

as a side note, the VIDEO_TS ripped with DVDFab and process in DVD2One plays perfectly fine in VLC, no audio sync problems, so something is happening in the encoding process.

sorry for bringing this very old post back to life, but i assume this is preferred to a duplicate post.

i do have the AutoGK generated log but there does not seem to be any information that can be of use here, if needed please ask for it and i will post it.

i thank you all in advance for your help.

It sounds like you might have to crack open an NLE (Windows Movie Maker is terrible but may work), or dig into avisynth scripting to fix this. (The script would be simple, a few trims and audiodelays, but it could take some effort to learn the syntax.) AutoGK should have an advanced options that lets you read and change the script it uses, if you can find that then all you really need is to add something like this:

start = trim(0,43782) # in frames
firstchange = trim(43783,99523).delayaudio(1.1406) # in seconds
secondchange = trim(99524,0).delayaudio(-0.721)
start ++ firstchange ++ secondchange

Then encode as normal. Obviously the route means a lot of futzing about in vdub to find the right offsets first.

Since I have already offered a solution for you in this thread (http://forum.doom9.org/showthread.php?t=103361), you are kind of already making a duplicate post.

CWR03:

i think your solution in the thread above would not work in my case, the audio is not stretched or compressed over a period of time, the sync problem is one i have never seen before.

the audio is ahead of the video by about 2 seconds for the first half of the movie or so, then BAM, out of the blue the audio plays about 1 second after the video in the next half.

in any case, it does seem that passing the full disk rip through DVDShrink by "reauthoring" the main title only has corrected the issue. i did a sync check this morning before hitting work and the audio is in sync throughout the whole movie.

now if there are glitches here and there i am not sure, i have not yet watched the whole movie frame per frame, but my guess is this was the easiest solution to ripping terminator 2 extreme.

DVDFab -> Full Disk Mode -> DVDShrink -> Reauthor add main title only (no compression) -> AutoGK encode.

Thank you all for your help.

Waste of time. If you had done as CWR03 had suggested (DVD Decrypter in IFO Mode, choosing the angle you wanted), you'd have accomplished the same thing in less time.

hey manono:

i honestly did not ever see that suggestion, i must be absent minded, could you please link me to a solution as simple as the one you just mentioned?

thank you.

[CWR03]

could you please link me to a solution as simple as the one you just mentioned?
manono has given you the solution in parenthesis.

[loyalty_anchored]

not to be a butt here, but nanono told me you suggested that solution, and i never saw your suggestion, so i was asking for a link to it.

but thats ok, problem is solved so there is no point in continuing with this.

thank you both for your time and help.

In that instance, all that is needed is to pre-rip the movie with DVD Decrypter in IFO mode.

When I was writing the tutorial for AutoGK, I used T2Extreme for testing. You can see there's a pic in the tutorial taken from my rip of it. No audio asynch in the rip.
