Auto Gordian Knot: current version 2.55

[manono]

Hi-

BTW .. if you do sub/idx -> srt after AutoGK have made the sub/idx wont you loose a little moviequality because AutoGK will have reserved space on the CD for the subtitles

If your plan is to OCR to SRT or SSA or whatever format subs, then don't even bother telling AutoGK to make subs. As you said, it'll set aside space for them, and also waste a few minutes demuxing them. Just use SubRip to get them before, after, or during AutoGK by opening the IFO file. Then OCR from there.

I think that SubRip is a little bit better to do this with than Resynch because after you've done a bunch of them, and saved the SUM files, you build up a collection of SUM files. Then when you start to come across subs done by the same company, in the same fonts, you may not have to do any, or very little, typing.

Thankyou to both of you .. I'll do just that.

[CeeJay.dk]

On another note .. I have discovered that if you remux the avi's produced by AutoGK with AviMuxGUI , you can reduce that size of about 1mb (it varies) , and the movie stays just as playable or better (muxing affects seeking and playback from slow media).

The default settings in AviMuxGUI work fine , but it mentions that a few hardwareplayers have problems with Reclists so I suggest you turn them off for use with such.

Muxing with AviMuxGUI might be a good finalstep for AutoGK.

What do you think ?

[len0x]

AVIMuxGUI used to have much more problems with standlones than just reclists and I don't want to bring another application into the pack.

Good news for subtitle users - I've managed to put automatic resizing of subs and its position via hidden file, so that you won't see squashed subs too high with the burnt-in subs :) (this option will not allow you to control position, its just tries to restore original DVD subs). It will go straight into stable release, so no testing will be done...

There are no free DTS decoders available.


Actually, AC3Filter 1.01RC5 can decode DTS streams. It is what I use.

[Codesmith]

I am not seeing it at sourceforge.net?

Yes, that's true. Valex hasn't worked on it in some time and he didn't put the source up on sourceforge. There is a link here in the Doom9 forum.

There is a difference between playback filter and decoder...

[QNX]

than AC3 Filter can play DTS :P

[len0x]

What good does it do for us? We need a decoder that can be used in BeSweet/Azidts for transcoding.

[QNX]

for autogk - probably nothing

http://sourceforge.net/projects/ac3filter

it's DirectShow AC3 Decoder filter used to palyback AVI files with AC3 sound tracks and DVDs

;)

[len0x]

and you think I didn't know that?

[QNX]

dunno :p

you mean transcoding for DTS?

[CeeJay.dk]

Can you use Hybercube Transcoder ( http://hypercube.is.dreaming.org/ ) or dtsdec ( http://www.rarewares.org/others.html ) ?

[len0x]

Funny that nobody noticed that FDecimate and KernelDeInt were not updated in the package :) But looks like I'm not gonna be including new KernelDeInt anyway yet...

Get your point. However, if AutoGK is ever to support matroska, it would probably be a good idea to let mkvmerge do the muxing. VDubMod does have problems with special chars and track names and is generally not the best muxing application around ...

[len0x]

Its time to have some rest for me (and I have enormous workload at day time job these days), so I just got this out without new tutorial. For a week or two I do not plan any new updates.

Can autogk create subtitles in a file? (like .srt format).
When you select to use external subtitles has any difference if just don't select a subtitle language?

No.
AutoGK creates either burnt-in subtitles or external subtitles in idx/sub format.

In order to get a .srt file you can use SubRip on the idx/sub files. (OCR). The procedure needs some hand work.

[Exoskeletor]

Im using every time subrip cause i dont like the burn-in subtitles or im downloading the subtitles from the net.
It could be nice if autogk could done that but i think it's impossible

[len0x]

no, only *.idx/*.sub

It has! External doesn't mean all, you still have to select which ones you want

*edit* Hobojobo was faster :)

[Codesmith]

It is just me, or is SPDIF output disabled for everyone.

I tried 1.01a RC5

I use a digital connection to my home theather setup for sound, so having an DTS decoder doesn't help me. What I really need is DTS passthrough!

[Bardock]

I've always used GK, and when I discover AutoGK I get impresed, because it was very easy, and I ripp lots of movies, so I win time.

But, the quality I get is not enought. I think, it will be usefull to let the user modify the codecs settings, or at least, making profiles like fast, standar and slow.

I used to use xvid with: H.263 matrix, vhq 4, trellis, chroma motion, adaptive quantification, one max bframe, packed bitstream, and sometimes turbo. This way, i get much more quality and they are almost full compatible with my SIGMA player.
The ripps I do with AutoGK in xvid, don't have the same quality, and don't use to be so compatible, they make sort jumps in complex scenes. I think this is because H.263 matrix is more compatible.

If you give freedom for choosing to advanced users, I think it will just be the perfect tool!

I think its a known problem with RCs... but sadly it doesn't look like its gonna be fixed any time soon.

Why would you think its a tool for advanced users? Because its not...

[Bardock]

I don't think that is a tool for advanced users, but advanced users that ripp lots of movies could take benefit from some AutoGK features.

I think an aplication doesen't have to be only for advanced or beginners, it could be for both.
But i also thing, not only advanced users may thank more codec control.

AutoGK rocks! its a fantastic tool, but in my opinion this will improve it

[AlmanNewfred]

I selected 'Display only forced subtitles', but in the two encodes I have done with 1.60 all subtitles were burned in.

Sorry if this was addressed elsewhere, but I couldn't find it.

What do you see in IDX file? ON or OFF for forced subs ?

[AlmanNewfred]

(edit)

Never mind, I am an idiot. For some reason DirectVobSub was running which never happened before. Sorry...

[QNX]

new question

is there any chance to implement WMV9 encoding in autogk? :D

[len0x]

[ydobon]

Hello all.

As I've mentioned before, I'm heavily using AutoGK for .ts --> .avi conversion. As AutoGK (actually DGIndex) takes the whole .ts as input, I've made kind of a breakpoint for VirtualDubMod to be able to select just the video I want (no initial or final remaning frames, and best of all, no ads!).

In a way it's similar to AutoGK Tweaker (http://forum.doom9.org/showthread.php?s=&threadid=79227&perpage=20&pagenumber=1), but I made it so I can prepare a few encodes, go to sleep and find the work done in the morning. No user intervention in the middle.

I've made it as simple as I could, the source code is available and I've tried to comment it as well as I could. It shouldn't be very difficult to adapt it to other necessities (modifying AVISynth filters, adding filters to VirtualDubMod, etc).

If you want to take a look, you have it at http://ydobon.cjb.cc/

If you do, I'd appreciate any bug report, suggestion or comment.


Regards,

P.S. Will the YAAM (Yet another AutoGK modifier) acronym be necessary? ;)

Mmmm. Now I've noticed that when I skip a large amount of ads, AutoGK has already decided the resolution and it's pretty underestimated, so the final AVI results undersized... I'll have to think how to go around this...

[ydobon]

Hi again.

In the _.avs that AutoGK uses there's a
SelectRangeEvery(180,18)
and in the *_comptest.avs there's a
SelectRangeEvery(300,15)

Are those numbers always the same? If not, how are they calculated? I'm asking because I'm trying to compensate the "ad removing" I mention in my previous message.


Regards,

[len0x]

Originally posted by ydobon

Almost - its 10% or 2000 frames whichever is greater for comp test and 5% or 1000 frames whichever is greater.

P.S. I think the whole approach of changing the sources at avisynth level is wrong. Automate step described in Q 6.6 of FAQ is far better idea.

[ydobon]

Hi, Len0x.

The main problem with the Q6.6 approach is the same I have with the ".ts cutter" I use: You can only work with keyframes. If I want frame precision, there only two places I can touch: the .avs and the .vcf

There's also the problem of cutting in the middle: Q6.6 only allows trimming (left and right) the video. It's not possible to skip the ads.

I prefer editing the .vcf because I'm more familiar with VDub scripts, and because I see more possibilities for the small tweaks I like: selecting fragments, cropping, fadeins/fadeouts, ... but for long ad pauses, the video result undersized.

Right now I'm doing a two-step workaround: first a rough cut with a .ts cutter, then deleting at frame level with my program. Quite a job, but still way easier than the old do-it-all-yourself :)

Thanks for the info on the numbers, BTW. If you don't mind I've got another question: Is the resolution determined by the info after running *_comptest.avs or do you use something from the _.avs?


Thanks in advance.

[len0x]

_.avs file is used only for analysis, nothing to do with comp test and resolution.

Why don't you just edit TS in ProjectX and save it as TS again?

[ydobon]

Hi,

because projectX cuts only at keyframes (I frames). That's about 1/2 sec of resolution in my .ts files. I'd like to have frame resolution.


Thanks for the info.

would you mind me saying - what ??? :)

[len0x]

I'm playing with a new denoiser for next version of AutoGK (that would be RemoveGrain in mode 2). For speed reasons and actually compressibility I'd like to move denoiser after resizing (which will become sharper with new Lanczos4Resize as well). Anyone here thinks its not a good idea or everybody's happy? :)

[ydobon]

Hi,

Originally posted by len0x

You know, those words had sense when I composed the sentence in my mind, but now that I read them... :)

I meant that my videos in TS format have around two I frames per second. So if I can only define cutting points at I frames (a-la-ProjectX) I can have up to 12 frames of garbage that I can't cut out. In ProjectX, DVR-Studio or DGIndex I can make cuts every 12 frames. At the VDubMod level, I can cut any single frame.

Oh, and I forgot to mention doing it this way saves me the time of re-saving the .ts file (they're usually 2-5 GB, but if you want to process a few of them, it takes a while).

Regards,

[Taurus]

I was just up to do some tests on my own with Removegrain and
Lanczos4Resize.
I will post my conclusions in one or two days if you want me to do so.
I will use HVS Best Matrix, HVS Good, Mpeg and H263 for my tests.
Source will be a sample of a Buffy rip.

Cheers

Speed: not measured, clips too short.

Visual appearance: The source is pretty bad, but to my eyes, removegrain in conjunction with lanczos4resize does a pretty good job.
Just look at the specs.
There is some bugginess if you compare the numbers, I don't know where they come from. Did my best not to mess up the scaling.

The author of removegrain suggests to put the filter before any cropping.http://www.removegrain.de.tf/

To my opinion, this needs a little more testing.

Already tried Mode=8 on another sourc. Works quite well, but should be out of reach for implanting in AutoGk.

Thanks for your good work, anyway.

Cheers

Weird though - lanczos4 is softer that lanczos3 and I though it should be vice versa (the only time it was correct was mpeg matrix)

[Corence]

Would it be possible to have some sort of visual notation showing if ESS compatibility is enabled after the installation? After updates I sometimes forget if I remembered to check the box and have to reinstall to be sure. This wouldn't be necessary if there were a checkbox showing that ESS compatibility was enabled.
