Auto gk - various issues

[mr soft]

I am playing with a couple of ripping programs at the moment and have just tried auto gk . The beauty of Auto gk has got to be ease of use , oh and dual language is the best .

My problem is I tried to record both languages in vbr 256 on my latest rip, but on playback the sound lagged by a second or two . My first rip of a different movie was ok (soundwise)

I also noticed in the tutorial that divx 5.2 is discussed , I am using divx 6 and there does`nt seem to be many guides on this codec . The doom9`s guide is also last updated on 2005 for divx and xvid . (not complaining ED. forum is top notch)

Two last things , the target quality is one pass (auot gk)
If set to 80% will this overide the divx default of 60% and are one pass quality based programs going to make two pass a thing of the past?

You may have a title with an advanced copy protection. The audio skew is easily corrected with VirtualDubMod.

It doesn't matter with AutoGK, since there's nothing you can change in the codec settings that will affect the final file.

Yes to the first part, definitely not to the second. Two-pass encodes can have a far better quality at the same file size as a 1-pass, or have a much smaller file size with the same quality.

Thank you for the quick response CWRO3 .

I tried the vitualdubmod on this file and was told that it detected an improper vbr audio encoding (back to cbr] I think it's easier to rip the file again.

Am I correct in thinking that the files I have created using the one pass quality settings can now be run through another program for the second pass and if so which program ?

The predefined setting in auto gk, Am I right in thinking that the larger the file size the better the quality? e.g. Standard 90 min PAL, 2x languages at 256 kbps predefined 1.4 gigs? Also taking into account I'm using min. 740 width (no min height, not sure why not}

Once again thanks for the help

Just click "No." All will be fine.

No, because the .stats file wasn't created for a second-pass encode.
The predefined setting in auto gk, Am I right in thinking that the larger the file size the better the quality?
Yes, but determining the end file's quality can't be determined based on anything but actually encoding the file. After you've done a few you'll have a better idea of what to expect and what settings to use, but the needs of a 2-pass encode vary too much based on the content of the movie to accurately estimate the end quality. Also be sure not to use the exact number of 1400 MB, or AutoGK will split the file for two CDs.

[mr soft]

I clicked no and there was no change. Ok, I backed up a different movie using auto Gk.

Two languages cbr 256 kbps. Will try vbr again at some point soon, as I prefer this.

When played through winamp the message appears multiple audio, however second language is not accessible. If I fast forward the movie, audio / video sync stay intact.


When playing through latest divx player multiple audio is available, but if fast forwarded, plays havoc on the vid / audio sync. This is before and after usage of vdubmod.

Ps. Why is height in auto gk so small, First file = 608 x 256 second file = 720 x 320 (720 min width chosen, also refers to first post ref. 720 x 480) will this be resized ok on playback of standalone player? Still waiting for Packard bell dvx 460

I have since discovered 7zip and am going to play with mpeg mediator and MkvMagic

[mr soft]

Ok I left this thread for some time to play a little ,but am still having the same problem . I rip the files with dual language ; cbr , vbr , 192kbps,160kbps, does´nt matter . On play back , if I fast foward ,the audio ,video sync is way out.

This is not just on one file , and is not restricted to new movies. This does not happen on single language rips . I would like to continue in dual ,as it helps me to learn another language .

These are the agk results backing up oceans eleven . duration:1.51 min.

These are with ac3 sound:

1. Target size: 2040Mb - Chosen resolution is: 720x304 ( AR: 2,37 ) Predicted comptest value is: 69,02%

2. Target size: 1493Mb - Chosen resolution is: 656x272 ( AR: 2,41 )


This is with cbr 160kbps

3. Target size: 1493Mb - Chosen resolution is: 704x288 ( AR: 2,44 ) Predicted comptest value is: 60,44%


I,m goin loopy. The first example is looking good , but is there a way to drop my file size a bit without loseing comptest value? as 2gigs is getting a little large.

Should I be worried about these AR: figures ? I just replied to myself with a post.
Any chance you could move it Ed. thanks

Hi,

I will reply to this post but reading this thread I do not know if your audio lag is still pending... If so you could rename your title to something more general like "various problems with Autogk" and ask a mod to move this thread to the Gk/AGK section.

Now, in 2pass mode you can tune the:
- output size
- audio
- soft/sharp matrix
to adapt the params to your needs.
In your case if you keep same audio, same output (and same matrix), you can choose a fixed width (advanced settings) of 688 or 672 or lower and your quality percentage will rise.
You can abort the encode after the comptest and watch the different comptest.avi and keep params which suits you best.

Concerning the AR, AGK crops/resizes to be mod16 compliant so depending on resized resolution you will have slight AR changes.

For a 2.35 movie I aim for 640 minimum width, sharpmatrix. For a movie length of less than 120mn the output size will be
1/4 - 1/3 of DVD if audio is Ac3 or
1/5 - 1/4 of DVD if audio is MP3
depending on compressibility and final quality wanted.

Hello BigDid .

Very interesting , and helpfull. Just googled sharp matrix and this came upIf I am not mistaken, AGK will automatically force sharp matrix if a fixed size is specified, check the logs.

+1 for letting AGK use it's internal resizing feature, it will use sharp matrix for a minimum size of 608 up to 720 (maybe less than 608 if aspect ratio is different but 608 minimum is sure).

I just ripped a mov.duration 141min ac3

Chosen resolution is: 672x288 ( AR: 2,33
Predicted comptest value is: 68,19%

Things are looking much better. I will do a lot more comptests thanks for the tips .




I sure messed this thread up alright , hopefully the last time .

I sent a private message to killingspree asking if it could be moved, not sure if this is the way to contact mods. ::confused:

Hi,

You are welcome, I am glad it worked.

Concerning my previous contribution, I still go for 608 minimum width but for real 16/9-1.85 movies; not for for the extra wide ones for which I now go for 640 minimum.
Concerning sharpmatrix I did'nt want to introduce confusion as it can manually be set. If not set, AGK will use auto/defaut settings which are detailed in sharpmatrix item inside the hidden options in the tutorial.

I sure messed this thread up alright , hopefully the last time .

Not necessarily messed up :cool:
1st step is to post in the thread cause mods do read threads :D
2nd step if no response in 1/2 days is to PM one of the mods in charge of the section
You have done both; so wait and see.

you can also use the 'report post' option to send an email to all moderators.

anyway, i will move this thread to the autogk forum for you.

Hello Jel,

Thank you for moving the thread.
When reading the note inside the report post template:
This is ONLY to be used to report spam, advertising messages, and problematic (harassment, fighting, or rude) posts.
, I thought, until now, it was not advisable to use that method for a move thread request ...

Thanks jel and thanks Did .


Ripped my first xvid today . mental speed 33fps.I will play with this codec a bit more. I have been afraid of xvid only because of the extra options. 1 wrong click = 2 or 3 rips

I´ve been using 6.4 ,so I missed out on some, hidden options, bennifits of agk. ie; the sharp matrix.

Ps are the psyco vis enhancements ,and h263 optimized, ignored in favour of a faster encode.

Insane or extreme quality sure sounds better than balanced.

Hi,

I don't use Divx and prefer AGK for it's SAP (stand alone players) compatibility so I can't compare with psyco etc...
In AGK either you go for max SAP compatibility using the ESS setting (hidden options) which will use H263 as soft and Mpeg as sharpmatrix, either you use MTK or no SAP settings and AGK will use Jawor 1cd for soft and Sharktooth EQM V2 as sharpmatrix.

I still use H263 for anims, Jawor1cd for medium/low bitrates and Eqm V2 for medium/higher bitrates.

If I max the bitrate (Sharpmatrix 2pass more than 100% quality) and AGK wants to redo 1st pass and shut off the B-frames, I go manual encoding and use Eqm V3 HR/Heini modified and other sharpening/enhancing filters.

Interesting once again , and this does not affect the sap I imagine.

There goes the rest of my day on google . :confused:

Hi,

Depends on the SAP, mine has a 1389 MTK chipset, accepts qpel and custom matrixes.

There goes the rest of my day on google . :confused:
* Manual encoding with VirtualDubMod; the same one used by AGK

* Eqm v3HR/Heini see: http://forum.doom9.org/showthread.php?t=83125
post 1 and following for basics
post 284 for heini modified matrix

* sharpening/enhancing filters; this is avisynth stuff and quite difficult to manage (I am still a beginner) look in the avisynth section for infos

Sidenote: AGK uses and reuses avisynth scripts (.avs extension) just look in the agk_tmp folder :)

Thanks once again for the detailed reply . I will be loking into all as I´m a curious person, hence all the posts.
Who knows maybe one day I´ll be on to GK fully custom.

The audio is still an issue ,less because of ripit4me .
I only do ac3 now
Is there any way of telling if an ac3 will be out of sync before the rip?

Hi,

I can't help you for audio 2 tracks, I do only 1 track.
You may have dvd audio tracks slightly out of synch; in this case it usually worsen when transcoded.
Usual way to fix: VDM/ Stream list/Source right-click/Interleaving/delay audio track by ...

Now to get the delay without using ears is the problem :)
Go from rough to fine: 10ms steps to 2/3 ms for nearly synched movies. I don't have bad synched ones anymore since using Ripit4me :D

[mr soft]

That was great , :eek: worked a treat. I left this file on my pc as I wanted to learn how to fix it. Worked on both audio. 180 ms delay did the trick. You were right ,the listening thing is tricky but you can abort after ten or twenty sec., and play the file to check.

Slightly larger file , went from 1.5 gig to 2.05gig
Is it wise to run it through agk again to shrink it a bit more? Also should this be something like 90% quality 1 pass this time.

I am going to try and rip an ac3 out of sync ,to try it again as that file was 224 cbr . I know your thinking he´s lost it .

@CWR03 Sorry I did´nt get it the first time, hence this stupid commentThis is before and after usage of vdubmod " I´m am as green as I´m cabbage looking. "

Eeeek...

That's not slightly out of synch. Next time you could widen your steps for 30 even 50ms.
I have seen once a small tool made by an avisynth guru that that could help getting the right ms delay for an audio desynch ... can't remember where atm :(

You mean keeping the original AC3 instead of a Mp3 Cbr audio recode?

Also should this be something like 90% quality 1 pass this time.
I don't understand this part, please elaborate

Edit: it could be Tmonitor from tritical see: http://web.missouri.edu/~kes25c/#c2 and don't ask me how it works, never used it.

[mr soft]

The quality is always going to be as good as your reception.
I´m getting a very good picture, and the signal is split and fed from the main tv. I mainly bought it to run a couple of old vhs´s through it into MPG2 .
Today I was watching tv ,saw something I liked ,missed it, rewound it and recorded it ,then Auto gk ,then emailed it .
I love my card.

[mr soft]

Sorry about that,that last reply was just plain soft.

Before VDubMod the bitrate was 1372 kbps
after it went to 2575. I imagine this was because When I save as , I chose full process mode (direct stream ?)
I also changed the compression to the 6.4 codec and configured it to insane quality .
Also should this be something like 90% quality 1 pass this time
This part, I figured if I ran it through Agk again ,using the target quality ( being one pass only ) it would shrink it a bit more.

Thanks again
