Hi!

Although there are undoubtedly many other methods to resynch your DivX-compressed .AVI, the follwoing work(s) very nicely:

A) If the difference between audio and video is constant throughout the video:

Load the file into VirtualDub, VirtualDubMod, or NanDub.
Set BOTH "Video"(VirtualDub, VirtualDubMod and NanDub) and "Audio" (VirtualDub and NanDub - VirtualDubMOD>"Streams>"Stream list") to "Direct Stream Copy".
From the "Audio" dropdown menu, select "Interleaving" (For VirtualDubMOD, rightclick on the listed audiostream and then select "Interleaving")
Under "Audio skew correction", set an appropriate number of milliseconds (positive or negative) in the box labelled "Delay audio track by"
Save with a new filename

B) If the difference increases as the movie plays:

From under the "Video" dropdown menu, select "Framerate" - and select "Change so video and audio durations match"
Save with a new filename

Let us know of your success ;>}

I am having a similar problem. I have a leadtek winfast 2000 xp. It has software encoding. I tell it to record a show using mpeg2 optimal quality. The recoded video (although enormous in size) is fine, however when I try to encode it with autogk, the sound and the video get more and more unsynced. I am having this problem with other programs as well, so I'm wondering if either its a codec probelem on the machine, or if there is somthing wrong with the mpeg2 video. Any insight would be much apperciated!

Hi! ... thanx 4 reply ....

I checked the film and it seems that the difference between audio and video is constant.
I will try out the first solution tonight (it's a long movie) and let you know about the success tomorrow.

Bye the way, what's the difference between VirtualDub and VirtualDubMod?

I expected the resync would take also a few hours like the conversion, but it was only 3 minutes. So I'm finished right now and Solution one worked fine!

@setarip_old:
Is there a way to avoid the synchronous problems when converting with AutoGK?

Synch problems happen with ARccOS-protected disks - you can either rip it with DVD Decrypter and the proper PSL2 file, or resynch it afterward.

I ripped the dvd with dvd decrypter. But what is a PSL2 file?

Google your title along with "psl2," and search this forum if necessary.

I ran vobblanker, and it works. Audio is now in sync with video. Thanks guys.

Could you plz tell how e268?

If there's a general solution for the ARccOS-protected disks but searching for psl2 files or resynching it would be great.

Thx

Not sure if my dvd is ARccOS, but my sound was out of sync with video. So, I just ran my VTS 01 file (from DVDDecrytor) thru VobBlanker (goofle for dl).

I tried VobBlanker without luck, no psl2 file available for my DVD :(

Anyone knows how to synchronize ac3 tracks in VirtualDub? Any codec I must have installed? (AC3 filter already is)

Thx

I might have used the TS file instead of the VTS file (I forgot how I did it), but I found the proper reference here:

darkpepe

17th March 2006, 00:05

No luck. Thx anyway.

With the try and error technique I managed to set the delay quite accurate, but still not perfect.

Isn't there another way to sync the movie without having to save the file over and over again to set the right delay?
VirtualDub doesn't play the AC3 track when previewing :(

Hi-

Isn't there another way to sync the movie without having to save the file over and over again to set the right delay?

Yeah, open the AVI in Media Player Classic. Right-click the screen and go Options->Audio Switcher->Check the "Audio time shift" box. Now, if the dialog comes before the lips move, then you want to set a positive delay. If the words trail the movement of the lips, you set a negative delay. This delay is in .ms, and 1000 .ms= 1 second. Set a test delay and test it out in the AVI. Adjust until you get it right. Remember or write down that delay, and then use it when making the delay permanent in VDubMod.

And don't forget to set the delay back to zero and uncheck the box when done, or it'll keep that same delay whenever you play an AVI with MPC.

darkpepe

17th March 2006, 08:45

Thx manono! Didn't know about that one!

A funny thing about this feature is, you have to wait the whole delay time to hear any sound after the movie starts.

In my case it's more than one and a half minute, which just renders it almost useless, because it's more time than I would need to save a new copy with VD

I have this Problem also.:mad:
Thou when i use the exact same vobs with dvd shrink or nero recode and encode it to a mp4 file it works fine. (no audio sync isses)

also i have no sync issuses while watching the iso.

I'd like to know whats going on.

The dvd is Sky high zone 4. (and some others)

It was ripped with dvd decrypter in Iso mode, then mounted with deamon tools.

using auto knot ver 2.27

darkpepe

19th March 2006, 23:44

If nero recode does is right, maybe there's a way to find out the delay it uses for the audio stream?

darkpepe

21st March 2006, 11:38

Confirmed!

Used the same source for Nero Recode and AutoGK.
While Nero Recode joins video and audio flawless, AutoGK screws up the sync :(
Must be some sort of bug in DGMPGDec...

pstar

22nd March 2006, 06:28

So is it possible to update DGMPGDec?

darkpepe

22nd March 2006, 22:25

Maybe we should ask somewhere else, DGMPGDec forum for example. The newest version still does the same mistake.

Hi-

Before you go get yourself hammered in the DVD2AVI/DGIndex Forum for falsely accusing DGIndex of being buggy, lets make sure you're creating your AVIs correctly.

I guess these are ARccOS protected DVDs you have, so you know you have to clean them up first, before running them through AutoGK. There are better people than I that know about that, but I wouldn't accuse AutoGK or DGIndex of being the source of your problems if ARccOS is involved.

pstar

23rd March 2006, 07:21

I'm not accusing anyone of anything.

From what i've read about ARccOS vobs I'm trying to encode are not protected.

I've tried "cleaning" them anyway but still the same problem a rises.

All i want to know whats going on. I'm far from a expert on this and Google isn't helping as much as it normally does. :confused:

manono

23rd March 2006, 08:16

Well, you've already claimed that DGIndex had a bug, which simply isn't true. If your DVD isn't ARccOS protected, then have you decrypted using DVD Decrypter in IFO Mode (and not File Mode or ISO Read Mode)? That way you remove the chance of Angles or multiple PGCs in the same VTS from messing things up.

pstar

23rd March 2006, 11:50

Thanks Manono I'll try that.
Thou' I'm sure I have not claimed that DGIndex has a bug. To tell truth the I'm not really sure what happens after I press start.
What i do know is that the way i used to do worked and now with "Sky high", "Into the blue" and "Stealth" all zone 4. I'm not Pointing fingers just would like things back to the super easy way of before.

Maybe i should of started with a big thaks to the contributors of Auto knotGK, insteed of I have a problem.
Really sorry if i've upset/broken board rules.:confused:

manono

23rd March 2006, 12:42

My mistake, pstar. It was darkpepe who said, "Must be some sort of bug in DGMPGDec..." I'm not exactly sure where the problem is, but it's not with DGMPGDec (which contains DGIndex).

I don't know any of those films, so I can't say for sure if ARccOS or Rip Guard or other anti-copying technology is involved, or just faulty decrypting practices before running the movies through AutoGK. But I wish you luck.

@pstar

Hi!The dvd is Sky high zone 4. (and some others)
It was ripped with dvd decrypter in Iso mode, then mounted with deamon tools."Sky High" (as are, apparently, all Disney releases now) has "RipGuard" copy protection.

Although DVD Decrypter v.3.5.4 CAN successfully rip such DVDs, the rip is not "clean" - and this probably accounts for your synchronization problem. Do the following:

1) Use DVD Decrypter v.3.5.4 to rip in "File mode" (NOT "ISO mode") - select "ALL files" (NOT just "movie files")

2) Load the ripped DVD "package" into VOBBlanker - select a new location to output files

3) Set VOBBlanker to "Process all files"

4) Press the "Process" radiobutton

5) Use the new (From the new output location) DVD "package" as your source

Let us know how it goes ;>}

manono

23rd March 2006, 23:25

Hi setarip_old-

Thanks for your timely post. Now, I don't encode many newer films, so I rarely encounter these protections. However, I did back up a recent Disney Miyazaki anime release. Not knowing whether or not it had any screwy anti-copy protection, I ran it through FixVTS just to be safe and everything turned out fine.

So, let me try and pin you down on a couple of things, since you seem to know whereof you speak.

You said to decrypt in File Mode. Will it work in IFO Mode as well? That is, can you run it through VobBlanker if you have only the movie, as opposed to the whole DVD?

And FixVTS will do the same thing as VobBlanker, won't it? FixVTS can be run in place, that is, without creating another copy of the movie. It's slower that way than if you have a second drive to send the "fixed" copy, but I'm in no hurry.

And since we're getting quite a few of these threads about asynch audio and subs, and since it's natural to blame the problem on AutoGK, even though it's not at fault, would you have any interest in creating a full thread about the copy protections in use, how to spot them, which studios use them, and the easiest ways to defeat them so we can back up our favorite movies with the least problems? It would have to be a "newbie friendly" post, with "newbie friendly" remedies since many of the people here, especially those using AutoGK, haven't had all that much experience. I'll happily make such a post of yours a Stickie.

You said to decrypt in File Mode. Will it work in IFO Mode as well? That is, can you run it through VobBlanker if you have only the movie, as opposed to the whole DVD?As far as I know, VOBBlanker seeks the "VIDEO_TS.IFO" file, so you would have to rip in "File" mode...FixVTS will do the same thing as VobBlanker, won't it?So, I've heard. I've not had occasion to use FixVTS (It came out later than VOBBlanker), as VOBBlanker has served perfectly thusfar for all "RipGuard"-protected titles to-dateFixVTS can be run in place, that is, without creating another copy of the movie.Personally, I would never want to alter my initial rip. A modified second copy is fine with me ;>}would you have any interest in creating a full thread about the copy protections in use, how to spot them, which studios use them, and the easiest ways to defeat them so we can back up our favorite movies with the least problems?I'd be glad to create such a "sticky" regarding "RipGuard" copy protection but, with regard to "ARccOS"-copy protection, I couldn't in good conscience suggest any of the freeware "solutions" (some of which include the use of a combination of programs, plugins, etc.) because:

My personally preferred method of overcoming "ARccOS", regardless of the iteration, has always been to use the only true "one click solution" (ripping, compressing, and burning - as well as options to make 1:1 rips, join multiple DVDs, eliminate extras while retaining active menus, etc.) DVD95Copy, which is a commercial program - and I tire of being railed at over and over again by the same posters whining about, "If it isn't free, I don't want to hear about it" and being accused of "advertising" a commercial program.

Thanks manono

24th March 2006, 05:56

Oh well, it was worth a try. Thanks, setarip_old. Yeah, I'm looking for pure freeware solutions. But don't worry, you're safe from your detractors down here. :)

So, to recap, and please elaborate or correct me if I'm wrong:

RipGuard is a copy protection used only by Disney (and Buena Vista?), and can easily be defeated by decrypting the DVD with DVD Decrypter in File Mode, and then fully processing through VobBlanker or FixVTS.

ARccOS is a copy protection used by Sony (and Columbia Pictures?) and can usually be defeated using one or another of the methods as outlined here:

http://forum.doom9.org/showthread.php?t=107719

When is it useful to use DVDFab Decrypter instead of DVD Decrypter, and what has to be done afterwards, if anything? And it should be noted that I believe Sony has stopped, or is about to stop, using ARccOS.

@manonoRipGuard is a copy protection used only by Disney (and Buena Vista?)No, not only Disney. As a matter of fact, the first "sighting" of RipGuard was noted to be "Madagascar" by Dreamworks.

What I said regarding Disney and RipGuard was that apparently ALL (not "only") new Disney releases now appear to contain RipGuard copy protection...When is it useful to use DVDFab Decrypter instead of DVD DecrypterIt's been indicated that DVDFab Decrypter automatically replaces any and all unreadable sectors with "dummy" sectors, whether or not they are part of a protection scheme. That means that if you've unknowingly purchased a poorly pressed commercial DVD (and this has become a fairly frequent situation recently) and use DVD Decrypter to rip it, you may not be aware that you own a problematic DVD or that your rip is less than perfect - until you play it back.

In my opinion, the only thing I would recommend using DVDFab Decrypter for would be to try and salvage what you know to be an old, physically damaged DVD. And it should be noted that I believe that Sony has stopped, or is about to stop, using ARccOS.Yes, that was stated in an article in Forbes' online magazine but - The SONY movie "Capote", released the day before yesterday, is ARccOS protected...

I don't get it. Please tell me what I'm doing wrong.

I cannot get goblet of fire to have synchronous video and audio. I've ripped it with dvdfabdecrypter and after autogk was done, the audio and video were definitly way out of synch, and no matter what I did with nandub I couldn't get them right.

so I passed my original rip though vobblanker and that didnt' help either.

When I play my original rip (using dvdfabdecrypter) with powerdvd, it's fine.

How do I get it through autogk and have audio in synch?

setarip_old

26th March 2006, 21:47

@gsgleason

Hi!

The Region 1 version of "Goblet of Fire" has no special/newer copy protection. Try re-ripping your original, purchased DVD with DVD Decrypter v.3.5.4 (NOT DVDFab Decrypter) - and then use MPEG Mediator to convert...

gsgleason, assuming that setarip_old is correct in saying that it doesn't have any special additional copy protection, then decrypt the movie using DVD Decrypter in IFO Mode and then let AutoGK take it from there.

I was under the apparently false assumptino that dvdfabdecrypter worked with autogk. It apparently does not.

29th March 2006, 04:58

Glad to hear that DVD Decrypter v.3.5.4 worked for you ;>}

(The problem with using DVDFab Decrypter is that, purportedly, it AUTOMATICALLY replaces any and all unreadable sectors (whether part of a protection scheme or the result of physical disc problems) with "dummy" sectors)

darkpepe

29th March 2006, 07:25

So why does the DVD play correctly, and why does Nero recode have no problems converting it?

If it had dummy sectors where you should see some images, we should notice. And what do the dummy sectors have to do with wrong delays?!

What version of Auto GK are you using? I have just run into the same problem using 2.27 on two different movies, which neither are ARccOS protected. I even double checked the source for synch errors and didn't find any. I'm unistalled and re-installed 2.26 and I'm running them one of them through again to see if I just had a bad install.

Manono - Good tip with MPC.

darkpepe

3rd April 2006, 16:13

I've been dealing with synch problems like these with The Brothers Grimm, Madagascar, and The Cave. All of the discs seem to play fine on my DVD Player, but when I ran them through Auto GK (both 2.26 and 2.27) the audio was off.

With The Cave I was able to use a PGC Edit plugin (using the wizard) to rip with DVD Decrypter, create a PSL2 file and clean it up with FixVTS. I found the whys and hows and toolas at this link http://forum.digital-digest.com/showthread.php?t=56078 It had a godd explanation, guide and a link to a full install of the tools...which I highly recommend.

So The Cave was fixed, but I have ripped bothe The Brothers Grimm and Madagascar with DVD Decrypter and ran them through both Vob Blanker and FixVTS, encoded with DVD Shrink, and burned with Nero and each of them when run through Auto GK, had audio out of synch.

Is there any trick to using Vob Blanker or FixVTS or any other suggestions? The discs play great in a player but Auto GK doesn't like them. Any suggestions!!!
