Auto Gordian Knot: current version 2.55

[chain999]

First and foremost, Thank you len0x for this excellent piece of software. I've been playing around with Divx/Xvid for a year of so, but never really got it down. This tool makes even my best encodes look bad.:p

My question is: I use a ReplayTV and download the files to my PC. The files are .mpg and I can't find a way to use these to convert to Xvid. Is this even possible?

Since this program only recognizes .vob's, is there any way to convert the .mpg's to utilize this software?

I know I can use G-Knot to do this, and have with some success; it's just that being able to "set it, and forget it" is just too good!:cool:

[Christos]

@Lenox
How about adding a job queue? It would be very usefull when doing encodes of TV series DVDs.

[len0x]

@doshan

you can't edit that box anyway... and on the output selector dialog you can create new dir, so it always assumes it was created there...

@Christos

I realize that job queue is quite useful option, but as currently internal structure of the tool is being changed a lot - I can't promise you implenting it until support of divx5 is there.

@chain999

Are those mpeg MPEG2 files? If not then I doubt I'll ever support that. If yes, then I might support that at some point in the future, but there are some serious limitation to that. Anyway at this moment it's beyond the scope of the project (i.e. DVD-2-AVI)

[wertert]

just had a 2.5 hour train journey and i've spent it watching movies encoded by the great GKITFAST4U. One observation. A couple of the movies have the original ac3 soundtrack and, in places, this is really quiet. I'm using headphones and watching the movie on a laptop. Everything is turned up full. Anyone got any ideas on boosting the volume of the ac3 sound track ?

[len0x]

Many new features, plz test it properly.

IVTC/Interlacing detection was main goal for this version. It should detect PAL interlaced sources in 100%. For NTSC it looks deep into the source so that even if DVD2AVI reports 100% NTSC interlaced, new version will detect telecined sources there and IVTCed them.

If you are using AC3 filter (from codec pack of full GK) you can boost levels there...

Would be possible to see movie lenght in "Video info" bar? (based on ifo parsing)
Thanks anyway

Andres

That's doable. But only for IFO mode (i.e. when stream info file from DVDDecrypter is not present).

[majerle]

If ifo is present -> ifo parsing
else -> not movie lenght

I'am using 0.3, btw, and processing Matrix Reloaded (pal - rc2), gk saying a 1.75% of interlaced frames.
The movie isn't interlaced and running kerneldeint will slow down the process (a lot).

--- The interlaced frames, are in credits title :angry: --- (as far i can understod the log files)

I don't know how interlaced is determined but i would like a checkable button to say interlaced/not interlaced (or a % of tollerable interlaced ... :confused: )
Also, audio bit rate should be determinated after the comp. test, just to reserve more bit for video and less for audio (audio 128 in comp.test > xxx, audio 96 if comp.test < xxx).

Thanks for your GREAT JOB !

hm... Are those frames really interlaced ? (i.e. can you see interlacing in the credits manually when you open d2v file in vdubmod?). If they are - we have a problem. I have a threshold of 1%, so everything above would be deinterlaced. KernelDeInt can be used even on progressive sources without doing much damage to progressive frames. That's why I chose it. But it's slow, you're right...

*Edit* I was thinking - was that interlacing a part of movie itself?
(i.e. intended)

There will be no button :) I've spent considerable time removing it, so solution will be in internal tuning. That's why I need testing from you guys.

No, it shouldn't. I'm strongly against anything below 128kbps (and therefor resampling etc.) So auto mode will always chose only 128, nothing else. You can always overwrite this in the options...

[majerle]

hm... Are those frames really interlaced ? (i.e. can you see interlacing in the credits manually when you open d2v file in vdubmod?).

No!, I watched in vdubmod and they arent'interlaced. But in log file, in film there are very few interlaced frames reported (1 every ~100/200), and in credits they are more present(~3/50.)

About audio:
No, it shouldn't. I'm strongly against anything below 128kbps
OK, i hope for a ogm/mkv with ogg support ;)

Thanks

Andres

[chain999]

I'm having trouble getting the latest release (.3) to install. I started with .1>.22 but can't seem to get .3 to install.

Any advice?

[len0x]

@majerle

It's ok then. I'll just increase threshold for combing detection in decomb.

@chain999

what seems to be the problem ?

Can you do some tests for me please? Edit _.avs by putting threshold as 30 instead of 25 and then open file in vdubmod and do save avi. Then read interlace.log and see if number of interlaced frames is less than it used to be ?

[chain999]

Never mind about the install problem...figured it out.

Regarding your question on the ReplayTV files, they are MPEG-2 files and have a .mpg extension. DVD2AVI can use these files, and I have created Divx files using G-Knot with these files.

I'm still trying to figure out a way to use these with G-Knotfast4U. I tried just changing the extension from .mpg to .vob. That's fine, but apparently fast4U is looking for the stream info DVDecrypter creates. Is there any way to take a file on your hard drive and get this info? Or some other program that creates files like DVDecrypter, but without an actual DVD?

Sorry if this sounds confusing...there HAS to be a way to do this!:confused:

[len0x]

you can try faking this by creating stream info file (with 1 audio and 1 video stream) with DVDDecrypter and putting it into dir where renamed mpg resides (of the form vts_01_*.vob). it should work I think...

[len0x]

I just put new version online. I did pretty good job on making comptest working very accurate with XviD/brames(it's much more accurate than current test in GK).

Also final quality is diplayed after first pass so that you're able to see how accurate was quality prediction. If during adjustment process neither matrix, not resizer were changed than you should get pretty close figures, otherwise results may vary (in my tests up to 7-8%) since there is no way to predict how change of matrix/resizer will affect comressability for a given source.

At last I've increased threshold for interlacing detection, so that less frames should be reported as interlaced. If this still doesn't work for some of you I might have to increase % of the move examined for interlacing (now it's just 5%) - may be I'll go for 10%... Let me know how this works for you and we try to tune it :)

enjoy testing :cool:

Thanks for the info. I'm sort of following what you're saying, except I don't understand how I can create a 'fake' stream info file with DVDDecrypter. There isn't an option to 'create' a file from any other source than a DVD drive; how would I get it to read a file off my hard drive?

Another release already! I can't install these fast enough to test them.:D

Thanks for all your help.

[zerocoolnl]

Hey, nice you got the next update, but I just started the rip-process :p
I've got a question, why is the rip-process taking longer with your program then with Gordian Knot?
I always rip with DivX but your program on the moment supports only XviD. Is that maybe the reasen?

Thnx,
Zerocoolnl

btw:Nice program! It's working fine on the moment:D

[Crenshaw]

@chain999
to your problem with *.mpg Files, have you try to make with a vob-editor *.vob from the *.mpg like to make a dvd and then use dvddecrypter to "rip" this dvd
i dont know, whether this work (i dont makes dvds and i dont really know such things), but it looks possible
if you try, plz post the end, it interest me, too

Crenshaw

[len0x]

@chain999

just rip some small bit from any DVD using DVDDecrypter and then put the file (VTS_01 - Stream Information.txt) into dir where you have renamed VOBs. that's it (as long as you don't select audio & subtitles it should work).

@zerocoolnl

XviD encoding with parameters I'm using was always slower that DivX. You just have to get used to that (quality never comes for free :) ). Although you will enjoy the speed of DivX again when I add support for it (I'll be waiting for release of 5.1.1 to tune codec settings and empirical variables - it's quite a lot of work...)

[yotsuya-san]

Hi Len0x, in 0.31 "Preview" doesn't work with my usual test vob. All I get is a

[10/11/2003 22.09.00] Indexing input for preview.

in the log window, DVD2AVI starts (without working), then exits, then GKIF4U come back to its idle state.
Anyway, it encodes normally.

Bye, Yotsuya.

Ps Please add 112 kbps audio tab (with or without resampling :D ;) ) and another little suggestion: have you ever considered to detect ac3 mono and then reduce the bitrate (and greatly increase audio encoding speed) so video has more bitrate?

Thanks len0x! IT WORKED!!! You have no idea how long I've been waiting for something that did this so easily...and high quality. I'm going to play around some more with other clips and the latest ver. of your software.

The ReplayTV community is going to LOVE this.:cool:

If I could make one suggestion for future releases, it would be adding batch encoding...then it really would be the BEST out there.

Keep up the excellent work.:D


edit removed.

[len0x]

@yotsuya-san

oops, I messed up the preview :) Will be fixed in 0.32 tomorrow.
And yes, I will add increments of 16 instead of 32 to audio bitrates.

@chain999

Upgrades are easy. Just copy new files over old ones (after you extracted it from archive). No patching required :)

I think (correct me if am wrong) what chain999 is asking (batch encoding) is the same think as I did, a jobs queue. Meaning the ability to add multiple encoding jobs of different movies/episodes at once in a queue, then hit the start button and go to sleep (maybe a "shutdown when done" checkbox would be handy too). Anyway len0x already answered this and I don't mind waiting... :)

Can't seem to get past the compressability test. Virtualdub mod appears to complete the encoding test fine but then I get an exception: open avi failed.

Here is the last section of the log.

In first test, with threshold of 25 i have 174 frames and with a threshold of 30 i have 58 interlaced frames (no more in film, only in end credits), so if 25 give me 1.75% of interlaced frames 30 should give ~0.55% on interlaced frames.

Good!

Thanks again

Andres

[guspasho]

Well, I think the idea is great but I am having a few problems of my own that don't seem to have been reported yet.

1) Anytime I try to compress I get an error early on that says "Cannot determine the filetype of G:\ROOTSHARE\dvdtemp\jonze\tmp\_.avs"

However the log says

2) Some DVDs your program cannot find any audio tracks for, even though I can play them with audio fine in PowerDVD. Heist is one in particular that I'm referring to. I will select the input directory but the audio track never autofills like it should, the dropdown list is empty, and I cannot press start to continue.

TIA!

[zerocoolnl]

@Lenox
When I use Gordian Knot I was always about a half hour lost with compressibilitychecks etc. so I think your program is till faster, haha:p
It's easyer, and that's the point!

@Richie_Rich

Which OS are you using? Are you able to play test_comptest.avi? It looks to me like you might not have directshow filters installed properly (some ppl have troubles with it).

@majerle

So version 0.31 is working ok for you?

@guspasho

1) You probably don't have avisynth installed properly. Get one from here http://sourceforge.net/projects/avisynth2 (version 2.5.2)

2) Interesting. Did you rip the DVD with DVDDecrypter in IFO mode? Do you have "VTS_01 - Stream Information.txt" file in the input dir? If so, can you please post the contents here.

@All newbies

I realise that this alpha testing can be sometimes difficult, so please read carefully usage.txt file and make sure that you installed everything that is mentioned there. By the end of the week I hope to come up with full installer which will solve most of third-party tools related problems.

[Richie_Rich]

@len0x

I am using WinXP Pro v2002 Service Pack 1

I have no problems in opening and playing test_comptest.avi in either Media Player or VirtualDub Mod.

Might help if I knew what tries to open the avi at that point.

Maybe I have some directshow filters which may cause problems, are there any known problem filters.

I am at the moment processing the same clip in Gordian Knot latest and am now at 64% of second pass and haven't encountered any problems so far.

Did you do anything different from the first time?

[majerle]

@lenox

i try 0.31 and, without changing any script, i got the same 58 interlaced frames. So i thinks it's good.

bye

andres

[Richie_Rich]

@len0x
Maybe you misunderstood me.
I am unable to do any good with GordianKnotItFast4U so I tried the same process using GordianKnot v0.28.6.3 attempting to keep the same options as near as possible.

Not sure if that helps at all, just that one seems to work fine but the other hits this open avi problem.

The only thing I can find that seems to be a bit unusual is that when you first open the "test_comptest.avi" file in virtualdubMod, the first frame shows:

Warning: Nothing to output
bframe decoder lag

Not sure if this has any bearing on the matter.

BTW. The Gordian Knot encode finished perfectly. Great quality etc.
Also I very much appreciate all the work you guys put into these apps, I very much enjoy testing and using.

Richie.

qoute plz the .nfo File from DVDDecrypter, it look like the DVD has th audiostream(s) in LPCM, but with this audiotype zthe program cant work, it work only if you run DVD2AVI alone and extract audio to wav and move file thn in the temp directory from G4...

I have installes Gordian Knot and a few eeks later GkItfast4u. Nothing more and it works perfect, so if you thinks it's to hard to install the extra's GkItfast4u needs, you can just install Gordian KNot and the program. Then It's shure it will work.

This warning is normal.
I indeed missed that you used GK for the last job :)
So the problem is still there... hm... Which XviD codec did you install? the one from Koepi (24/06/03)? Can you laso tell us what GSpot is reporting when opening that avi file? If nothing helps I'd like to get that file (I assume it's not large) to have a look at it...

[len0x]

Some minor bits and pieces (bugfixes and features) + preview should work again.

I wonder if anyone tested auto split feature (when going for more than 1 CD). Also I had a report that sometimes FILM movies are being detected as interlaced. So i'd appreciate more testing from those who have NTSC sources (in particular I was told that Finding Nemo had some issues with GKIF4U, so if anyone has it, please test it).

Apart from that - either we have almost no bugz or activity is going down :)

Yes I did a 2CD rip last night. Worked fine.

[Richie_Rich]

@len0x

Not sure exactly what info you need from gspot, but here goes.
This is a valid AVI file.

The filesize is 31.3 MB (or 32,110 KB or 32,880,640 bytes).

The file's length is consistent with information embedded within the file, so it's fairly safe to assume that this file is complete - i.e. the file has not been truncated or otherwise damaged.

DirectShow claims to be able to play the file. The following combination of filters were used:

{F:\Test\tmp\test_comptest.avi} (Video Source)
{AVI Splitter} (Video Pre-processor)
{ffdshow MPEG-4 Video Decoder} (Video Decoder)
{Video Renderer} (Video Renderer)

The following codecs all claim to be capable of processing this format:

--> {XviD MPEG-4 Codec}
{ffdshow MPEG-4 Video Decoder}
--> {XviD MPEG-4 Video Decoder}

DirectShow is apparently able to play the file as well (see "DirectShow Render", below),

Hi, ive tested your program, excellent work :)

I encountered the following problems with version 0.32 :

Ninja Scroll - PAL 25fps 4:3

In this movie the second line of the subtitles is missing :confused: This does not happen if i use gordian knot.

Treasure planet - PAL 24fps 16:9

In this movie the video and audio was badly out of sync :confused: The setting was CBR 128. And yes it works fine if i do it with g-knot.

Enemy of the state - PAL 25fps 16:9

The program would not accept the input files :confused: This was the error: list index out of bounds (2)

Movies that worked fine where: MAtrix Reloaded, Jurassic Park, Below, LOTR TTT and leathel weapon 4. Matrix reloaded rip was ok. The jurassic park rip was fantastic :D !!! :). Below was good, ttt was fair on 2cd's. Leathel weapon 4 was also perfect on 2cd's.


Big ups to you for this fantastic program, if you need any more info let me know :)

OS: Windows xp+sp1 and latest updates
All dvd's where ripped with dvd decrypter (latest version)

I haven't had an opportunity to try the auto split yet, will try tonight or tomorrow.

As you know from my previous posts, the main thing I'm encoding now are ReplayTV files (MPEG-2 NTSC interlaced). So far the only issue I've seen, is if I try to encode a really small file <100MB, it does just the opposite of what you described above; it reports the interlaced source as FILM. This hasn't been an issue for me, as the only reason I tried such a small clip was for testing purposes. Anything else I've encoded (from about 800MB to over 2GB files), report back fine as interlaced and the encode comes out looking good.

I'll try and save some of the log files, and post them if I encounter any other problems.


***anyone try this with avisynth 2.53 yet? I saw this was just released. I'm to afraid to fix something that's not broke for now.;)

1) I installed AVISynth and I got past that problem on the first try so I suspect that is that. Thanks!

2) When I ripped Heist it was a while back and I used cladDVD 2.0, which only rips the VOB files when you select just the DVD movie. So I don't have any other files in my input directory. Might that cause it? Other than that I have no other information for you. I'll see about ripping other movies with different ways and see if that still causes anything.

[Richie_Rich]

After setting up fresh copy of WinXP and installing only required drivers, patches, DX v8.1b, Gordian Knot and GordianKnotItFast4U.

The program appears to perform flawlessly on the same input files.

Checking with GSpot, the exact same filters, codecs are being used. The only difference being my other setup has loads more codecs, filters installed.

So what does all this indicate. Looks to me that if you are going to test any new software such as this, it really needs to be done in a freshly installed system.

Who really knows what goes on inside the OS once many different apps have been installed, much too complex.

How can anyone be sure whether a problem such as I have had really stems from an application fault or a windows misconfiguration deep down within it's bowels.

Therefore, my advice would be to test any new software on a clean system in the first instance. This would be fairer to the authors and not cloud issues which may not even exist within the app.

Richie.
