Audio/Video Sync problems with AutoGK

[JimR]

I have ripped a DVD with DVDFab, then re-authored the movie using DVD Shrink (only movie + subs), then feeded the movie through AutoGK using the IFO file as input. All setting are left on auto.

I get audio half a second earlier than video, not very cool to watch! Any ideas?

Happy new year and welcome to the forum,

Before Ripit4me the shrink reauthoring methode was indeed the only possible way to get the audio in synch for DVD with heavy protections.
You can try FixVts after DvdFab and before reauthoring with shrink or you can try the complete Ripit4me procedure

I get audio half a second earlier than video, not very cool to watch! Any ideas?
If you know the delay you can re-synch in VirtualDubMod, see one of the how-to posts made by CWR03: http://forum.doom9.org/showthread.php?t=119444

Thanks that did the trick, great!

I ripped the DVD with Ripit4Me (only film + sub) and then used AutoGK to make the AVI and it worked at first try with embedded subs and all

:thanks:

I was quite sure of the result, so glad to know it also worked for you :)

Hey Guys,

Been There & Done That ....... in every way & direction to efficiently preclude, rather than re-process to correct audio sync issues!!

Finally resolved a solution which proves 'bullet-proof' for me:

1) RitIt4Me / Fix VTS / DVD Decrypter combo (sweet!)

2) DVD ReMake Pro to edit DVD's audio and/or video content (UpStream Editing INSTEAD of post-4) 'screwing around'!)

3) Run net result of 2) thru DVD2One

4) Process results of 3) thru AGKnot and voila!!!!! :p

Great NET content, good quality & A/V in sync ........ all quickly achieved, 1st time through!! :D

[This 4 step "recipe" was constructed from info & guidence from this very website!!!! ........I love this place!:thanks:

Why do so many steps if RipIt4Me and AutoGK does the trick? Have you found cases where that DIDN'T keep the a/v in sync?

Another question I have: I have had cases, like the Star Wars movies, where I just used DVD Decryptor and the VOB files saved to HDD were perfectly in-sync, but the DivX AVI file after AutoGK was as much as a couple seconds off! Is this what others have experienced, and using the RipIt4Me shell (instead of just DVD Decryptor) still corrected the problem?

Trying this now, but gotta do SOMETHING while the movie's ripping! :sly:

[Bardmaster]

Well it made no difference. Which would make sense since the ripped VOB files were perfectly in sync.

I don't understand: I had queued a dozen jobs for AutoGK and all the rest worked fine using the same settings (2-pass DivX with 6.4pro codec at roughly 1500 bitrate, auto=CBR MP3 at 192), but when it hit the Star Wars movies the output is horribly out of sync!

Does anybody have any ideas? This inconsistency might force me to resume my search for the elusive all-in-one, reliable DivX encoder...just when I was hunkering down with AutoGK and feeling I could just let it rip (sic) thru my entire DVD collection!

[setarip_old]

Hi!but when it hit the Star Wars movies the output is horribly out of sync!Probably related to the fact that all of the "Star Wars" DVDs are "multiangle" regarding opening credits...

[Bardmaster]

OK - and yes, AutoGK asks which angle to select and I pick the first entry, ANGLE1.

But how do I resolve this? Do I have to resync each file using VirtualDUB? I've heard that's a nightmare to get right!

[dwm4444]

Bardmaster,
I've run into this problem several times with multi-angle DVDs. DVD Decrypter apparently has problems with multi-angle titles; even though it gives you the option to rip only one angle, this does not prevent the out-of-sync problem.

I found a way to fix it by using the guide on this page:
http://www.dvdr-digest.com/articles/40_1.html

The procedure begins under "Question 2" with the words: "Okay the first step would be decrypt...". There are pictures to guide you through all the steps. Once you get your new folder, just run it through AutoGK as usual. This method has always worked for me. You'll need IfoEdit.

I did my rips using DVD Decrypter in file mode running AnyDVD in the background, but I assume you could do it using Ripit4me in "Full DVD" mode as well, since it uses DVD Decrypter. (When I tried fixing the multi-angles problem using Ripit4me alone it didn't work; I had the same problems as I had using DVD Decrypter alone). The "Star Wars" discs are old enough that they probably don't have any advanced protection on them so you could probably just use DVD Decrypter by itself.

There are probably better methods to do this, but this is the only one I know of.

Good luck.

Using DVD Decrypter in .IFO mode will definitely solve the issue with angles causing out-of-synch problems with the Star Wars disks. Remember to rip the subtitles since the usual subs for the aliens speaking are no longer on the video.

[Bardmaster]

Thank you both for your suggestions! :thanks:

CWR03 - Regarding the DVD Decrypter IFO mode, the guide that dwm4444 refers to indicates that author tried this method and it didn't work. Every other post I've seen suggests FILE mode and you must of course rip the entire DVD (as opposed to just the main movie). Nevertheless if you've had success with IFO mode I'm willing to give it a try, the fewer steps needed for ripn'recodn' the better! :)

I may need to skip out of work early today to go home and try this!!

note - wondering if Lenox can investigate adding logic like this to "strip all other angles other than the selected angle, if multiple angles" in AutoGK - that would likely complete this product and make it a true all-in-one AVI ripper!

[laserfan]

I get audio half a second earlier than video, not very cool to watch!I would add that depending on your playback method, VBR audio can wreak havoc on sync. I always use CBR audio in my AGK conversions to keep my Sigma players happy...

[Bardmaster]

The IFOEdit solution dwm4444 suggested worked fine for the A/V synching issues, but the subtitles for the aliens, like Jabba the Hutt, disappeared. I will try the IFO rip option using DVD Decryptor next.

[Bardmaster]

OK now I feel stupid: I can't figure out how to do what CWR03 is suggesting here:

How does one rip those alien subtitles? I tried with default settings and the Jabba the Hutt scene had no subtitles.

[CWR03]

You'll have to rip them separately with something like VobSub Rip. An .IFO rip won't include the subs.

[Bardmaster]

Actually, I've found that they do. The thing that I wasn't doing, newbie that I am, is actually selecting them from the list of subtitles in AutoGK. It appears like the "embedded" subs like this are normally at the bottom of the list, or at least I hope that's always the case.

It could be that I'm being too hard on myself: without any subs selected, a PREVIEW shows the Jabba subs...but the encoding job doesn't keep them. Why is this? This seems like a bug in the program!

When I select the "English (letterbox)" sub at the bottom of the sub list, the PREVIEW mode actually shows the subs duplicated...which per len0x's FAQ is normal, and the actual DivX AVI only has one set. But I still don't understand why these embedded subs disappear during encoding! Very frustrating!

[dwm4444]

Bardmaster,

Unfortunately I don't have any Star Wars discs. Apparently they put the "alien speech" subs in their own sub stream rather than flagging them as forced subs within the larger stream. There are lots of posts about this causing problems with normal backup methods. See this for some tips on how to identify where the subs are:
http://forum.doom9.org/showthread.php?p=686508#post686508

Maybe you can locate the alien speech stream, rip it using SubRip or VobSub Rip, as CWR03 suggested, and hard-code it in when you make your avi with AutoGK. I'm just guessing, though.

If you can't get it sorted out, perhaps you could start a new thread with a good title that might attract somebody who's figured this out.

Good luck.

[Bardmaster]

Tx for the link - I did end up finding the "should-be-forced" subs as one of the sub streams, selectable by AutoGK, and was able to add to my DivX AVI. One other oddity I found, however, was that along with these subs (Jabba's speech in Return of the Jedi) there also are occasional NAMES that appear at the top of the video! Like Burtt and Muren in the above example, before and after the first Jabba sub-speech, and doing this exercise for The Phantom Menace the name "Lucas" actually appeared after Sepulveda's subtitle dialogue with Anakin (after he knocked down Jarjar)! What is THAT all about??

[setarip_old]

Hi!

If I remember correctly, those are pointers to "Directors' Commentary"...

[Bardmaster]

Ack! That makes total sense, of course, but yet another undesirable element in the finished product! :angry:

Now I'm stuck trying to figure out how to get the "should-be-forced-but-aren't" subs for non-English speech on an English soundtrack WITHOUT these random names popping into the video. :eek: I'll have to review the other English sub streams available for each movie, I suppose. I am NOT planning to go in and edit subs frame-by-frame!

Compounding to this dilemma: I won't always know which films have such subtitles that should be forced but aren't...and won't know until full movie playback. Oh well, I will always have the original DVD's for re-ripping as necessary.

Isn't there an easier way to identify and capture these sub streams?

[setarip_old]

I am NOT planning to go in and edit subs frame-by-frame!This takes all of about 10 minutes, while OCR'ing in SubRip...
