help needed sync error on dual layer dvd's with autogk

[raebie]

I have used autogk for a long time now but recently i have came across a serious issue with it.If i go to rip a dual layer dvd the sync of the film goes out by miles on my finished avi is there any way to sort this issue. I have recently had to start using a program called handbrake to rip dual layer dvd's and the sync comes out fine with that. Why cant someone fix this issue in autogk i am not very keen on the quality of handbrake i think autogk is better quality please advise how i can sort this issue with autogk

Hi and welcome to the forum,

I have used autogk for a long time now but recently i have came across a serious issue with it.If i go to rip a dual layer dvd the sync of the film goes out by miles on my finished avi is there any way to sort this issue.

Nearly all commercial movies are on dual layers.
Audio out of synch is, usually, revealing a dvd with a strong and/or recent decrypting/copy protection!
Some decrypting apps are needed; search for anydvd or dvdfab ...

I agree on ease of use for Autogk but development has ceased, see info here:

Why cant someone fix this issue in autogk
Well, for one, because it's not an AutoGK issue. If you, as you said, have been using AutoGK for a long time, then you've also been decrypting dual-layer DVDs for a long time, as BigDid said.

You didn't say how you're decrypting these movies to the hard drive? DVDDecrypter in File Mode? In IFO Mode? DVDFab HD Decrypter? DVDShrink? What?

[raebie]

I have done a lot of dvd's in the past and everytime i get the sync issues i check the back of the dvd and guess what it is a dual layer dvd and not every disc is dual layer. by the way i should of said i have used every method. i used dvd shrink to start with and any dvd wich i have always had and then i tried using dvd decrypter in ifo mode and still i got the sync issues with autogk but not handbrake. i have tried ripping the dvd's all different ways. it is autogk that is the issue because if i use handbrake i dont get the sync issues on my dual layer discs.The first film i had issues with was the longest yard the sync was out by miles click was another dejavu alien 2 and 3 and so on i ripped these with handbrake and never had any sync issues atall. so that proves it is autogk that cant cope with the dual layer discs any ideas how to fix this issue

It only proves that your process of elimination is flawed. AutoGK won't just introduce audio issues if there isn't an underlying problem with the source files.

[raebie]

I am not sure what you mean by that

[setarip_old]

I believe that "CWR03" is suggesting the very likely possibility that your initial rip of the DVD was "less than perfect" and may require using a different ripping program.

1) What are the titles and region numbers of the problematic DVDs?

2) What ripping program and methodology did you use to rip the DVDs?

[manono]

It also means that many of the ones you converted with no audio synch issues were dual-layered DVDs, even if you didn't check. Therefore the problem has nothing to do with whether or not these DVDs are dual-layered.

You should also learn to write properly; you know, capital letters, punctuation, and the like. It's hard to take seriously someone that writes like a retarded eight year old. This isn't a chat room but a serious video discussion forum.

I have not used AutoGK or handbrake, but I have found that audio sync issues usually occur with movies that have some or many blank .5 second cells in the beginning of the IFO's of the main movie, usually associated with the newer ( though they have been around awhile now ) copy protections. Programs that use/read the IFO, like Cucosoft, make corrections for these blank cells, and the audio stays in sync. Programs like MeGui, which uses DGIndex, only decode the VOB, thus cannot delay the audio per the IFO reference.
Not many single layer discs use these type of copy protections, thus DVDDecrypter/RipIt4Me will still work on them. Dual layer discs, typically Sony titles, cannot be ripped with DVDDecrypter/RipIt4Me. Thus AnyDVD or DVDFabHD is necessary. But these rips do not necessarily remove the blank cells, which, in my experience, caused the async.

Thanks for that well thought out post, Capsbackup.But these rips do not necessarily remove the blank cells, which, in my experience, caused the async.
Bingo. DVDFab HD Decrypter is usually the decrypter of choice for these difficult DVDs. As you say, though, it doesn't always give you a 'clean' decrypt. Synch issues can sometimes arise in spite of using it. That's why it's often a good idea to run the decrypted VOBs through FixVTS to remove those unreferenced cells before sending the IFO or the VOBs to AutoGK. If using DVDFab HD Decrypter, it's also a good idea to use it in 'Main Movie' mode.

Sometimes RipItForMe is enough because it runs the result through FixVTS by default. That's enough for some copy protections but not for all. setarip_old is a bit of a specialist at what works with what DVDs and if raebie gives some specific examples to setarip_old he may be able to provide some specific solutions.

when i rip a dvd it is from an original so it is not cause it is from a bad rip. I have tried ripping it with dvd decrypter and dvd shrink and clone dvd and still the same issues with autogk. I have started ripping the exact same films that have been ripped with dvd shrink and dvd decrypter and clone dvd on handbrake and i dont get any sync issues atall so how can you explain that if it is not autogk that has the problem.My dvd's are all original region 2 dvd's.And by the way i did give examples of some dvd's above i will list again some of them The longest yard,click,Dejavu,aliens 2,aliens 3 and so on and i also have any dvd's latest version

Hi,

I would like to be sure that I see your point (and that you are able to see other posters point, me included!).

From the quote above you want to demonstrate that the fault is on AutoGK. OK I follow you. AGK has audio synch that handbrakes does not.

Now where do we go? AGK will not change, hence our workaround propositions:

1/ As you stated having the original dvd you can try dvdfab for ripping followed by AGK to see if it solves your problem (it works for me)
2/ As proposed by Manono, you can try fixVts on your already ripped sources with dvdshrink followed by AGK
3/ Or you can try a mix of dvdfab+fixVts followed by AGK

Now that I have given some propositions, let me give you my point: You are free to try or not these workarounds but until you come back with some results I will not post anymore.

You may have noted this forum is (usually) oriented on practices and trials for resolving problems, not (or much less) on arguing or flaming.

@raebie

During this current period of problems you're having with AutoGK, have you had any successful AutoGK conversions?

If so, please provide the titles of these source DVDs.

Also, are you using Handbrake under Windows (No decrypting ability), or Mac (decrypts), or *nix (decrypts)?

[CWR03]

I have tried ripping it with dvd decrypter and dvd shrink and clone dvd and still the same issues with autogk.
As already explained, none of these tools will properly rip a disk with certain advenced copy protection schemes. They will leave in cells that won't affect playback of the ripped files but will cause an audio delay when re-encoded by AutoGK. It is not the fault of AutoGK because it was never designed to remove such problems.

I have started ripping the exact same films that have been ripped with dvd shrink and dvd decrypter and clone dvd on handbrake and i dont get any sync issues atall
Then use Handbrake.

[raebie]

I am going to use the dvdfab method tomorrow along with fixvts method and i will let you know how i get on thanks for the help i will let you all know if this method sorts my issues thanks

[raebie]

Thanks for all the help guys you where all right ripit4me and dvdfab worked percfect no sync issues atall with autogk thanks for all the help and sorry for being a pain

[Capsbackup]

@raebie;
IfoEdit can be a very helpful tool and save you time, by first checking for these blank cells and potential audio sync issues before using AutoGK. Just open the .IFO file corresponding to the .VOB files of the movie you want to process, and look for these .5 second cells before the start of the movie. If there is not any, it should be safe to proceed. If they are present, use the above mentioned successful procedure to "clean it up".

Hi,

You are welcome. Good ripping and coding.
