OUt of sync

[Markt10]

I'm a humble user of Auto Gordian Knot for over a year now for backing up DVD's for personal use on Windows Media Center.

Lately and ever so more frequently I'm running into DVD's where the sound is out of sync. Usually this happens to DVD's when encoding via AGK you can choose between multiple angles (?). These are usually a couple of seconds running up to approx. a minute. The problem happens when using Xilisoft and DivX convertor as well. The only program that seems to handle the files properly is Nero Recode encoding to AVC. Know it's not my intention to use Nero because of an incompatibility issue with Win Media Center.

Samples are Casanova, The Detonator, etc...

Please advise because I'm a huge fan of Auto GK...
:thanks:

Hi and welcome to the forum,

I suppose the above titles are recent movies; good(rather bad) chances that they use recent and more aggressive protections like Arccos etc... lots of examples in the Decrypting section. If so one (free) answer: use Ripit4Me in movie mode instead of DvdDecrypter.

so, do think that ripping with RipIt4Me will solve the sync issues? how come NERO Recode can encode to an MP4 file fine (no sync issues) when ripping with DVD Decrypter...just curious.

i've been pulling my hair out trying to get Anchorman encoded to XviD for my new Creative Zen Vision M...going on a trip today.

Hi,

It works for me; from the linked post above:
3. For recent DVDRip I have 9 of ten perfect rips without desynch using Ripit4me (in movie mode). I suppose I made a mistake for N°10 (HP & Goblet of fire); give it a try: http://www.ripit4me.org/index.html

how come NERO Recode can encode to an MP4 file fine (no sync issues) when ripping with DVD Decrypter...just curious.
I don't use Nero so I cannot answer but the author(s) of Ripit4me has indicated in his guide that the AGK out of synch may have something to do with the way Dgindex/Dgdecode works.

thanks for the help BigDid...followed the instructions for RipIt4Me and am re-trying Anchorman right now...will let ya know how it turns out.

thanks again.

I remember taking a look at the problem a while back. The problem comes from the fact that you have several tiny cells at the start of the movie PGC in some DVDs, and these cells are actually not played by the player (they're skipped via cell commands). But DGIndex does not know that and assumes they're part of the movie, which can cause delays between audio and video (because these cells may or may not have audio), and that causes AutoGK to have a missync. I think RipIt4M in movie-only mode or the plugin remove these tiny cells, with the result that the mis-synchronization is then gone.

Hi Jean,

Thanks for your interest; you may have seen it has been, and still is, a great concern for AGK users. A while back I was hoping FixVTS could have scanned the result of the DvdDecrypter rip in IFO mode, but that was not possible. Hence my relief when Ripit4me and it's movie mode appeared.

Yes and before Ripit4me the only way to have that kind of rip in synch was to (and still is):
1. Rip in File mode with DvdD (eventually run FixVts after)
2. Use DvdShrink in re-author mode

Thanks for your feedback...

I haven't had time yet, but this upcoming weekend I'll see if I can tackle these DVD's.

I'll keep you posted!

[Markt10]

Initial test are very promising. Thanks for the advise!!!

Glad to know our suggestions were useful. Happy encoding :)

I have had the same problem. I've used AutoGK with success for years. Now (with most recent beta) some of the encodes are out of sync. The time of the resulting encoded videos is usually a bit too long, usually less than a minute over time, sometimes a few minutes.

These weren't ripped with DVDDecrypter, but with the newest build of DVDFabDecrypter. That is supposed to be up on all the latest copy protection schemes.

Does Ripit4me catch things that DVDFabDecrypter doesn't?

As the OP wrote, if I try encoding from the same rip using Nero Recode 7, the video ends up the correct length, with the audio synced correctly.

Any chance it could be a bug in the new beta of AutoGK, or one of the programs installed with it? Might it be a good idea to regress to the stable version?

[Yo]

I just tried running FixVTS (newest version) on a dvd-video I had encoded before with AutoGK, that resulted in out-of-sync video-audio. (As described, previously ripped with DVDFab.)

FixVTS reported that it had fixed various things. THen I ran AUtoGK on the (VTS-fixed) files. I ended up with the same problem--a resulting out-of-sync avi, in this case with the video being about 7 minutes too long. (The length is shown correctly in choosing the PGC to import into AutoGK, that was true also before I ran vtsfix, but the resulting video is too long, with the end becoming increasingly out-of-sync.

Anyone have any other ideas?

[sturmie]

everything worked perfect...thanks for all the help!

I am getting the same problem, I have seen the audio out of sync on Disney's Greatest Game ever Played, Glory Road, and United 93 are three examples. I am trying the ripit4me option to see if that works and solves the problem. But it has been a problem with newer DVD's.

[CWR03]

amcfarla, the titles you've listed all contain RipGuard protection, which will always cause audio synch problems with AutoGK. RipIt4Me should solve it, but it's easy to repair manually with VirtualDubMod.

[amcfarla]

That seems to have resolved the issue using the ripit4me, the sound is now in sync with United 93. Thanks for everyone's information on this issue.

[amcfarla]

But the Greatest game ever played still has a couple second sound delay from the picture using ripit4me.

[jeanl]

in movie-only mode?
THen, take your ripit4m rip, open it in PgcEdit, go to the movie PGC and double-click on it. See if there are any leftover tiny cells at the beginning of the PGC (you can use PGCEdit's preview to see what's in there). If there's still a tiny cell remaining, you can remove it with PGCEdit save, and try again... :(

As I suggested, you can easily correct the encoded file using VirtualDub(Mod). It's already on your system because AutoGK uses it.

@amcfarla

Hi!the Greatest game ever played still has a couple second sound delayThis is a Disney release (original "RipGuard" copy protected), and can be properly adjusted by loading your ripped version into VOBBlanker and selecting "Process all"...

Hi, im having problems with out of sync audio on my avi files from autogk,
I'v tried using ripit4me and removing the cells but its still out of sync.Any tips anyone?,I'm fairly new to video conversion.
Have you read any of this thread at all? There are multiple solutions already listed.

[orchids00]

after going through this thread, i can't stop myself replying in this thread.
With ac3 audio, the avi movie created by gordian knot package play well in pc but it is out of a/v sync in divx certified dvd player.

There is no such problem with avi with audio in mp3 format.
can anybody suggest the solution?

@CWR03

On the previous page, you mentioned that you could easily fix the encoded files with sync problems using VirtualDub(Mod). I encoded an entire season of a recent TV show, which has this out of sync problem. How do you go about fixing the already encoded files? Can you point me to a guide, or if it is easy enough, explain how I can fix these without having to rerip and re-encode all the files again? Thanks in advance!

[setarip_old]

@SiKKo

Hi!

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".

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

video:

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 ;>}
