Attempt at Gknot w/ YV12

[colordog]

Howdy -

I saw in a FAQ that people have gotten GKnot to work with VDubMod in order to take advantage of the speed increase with the YV12 colorspace. I tried it out, and got a "Couldn't open log file error". So then I tried opening the AVS in VDubMod, and was told that the filter wasn't an AVS 2.5 filter.

Speficially:

I already had Gknot 0.27
I uninstalled AVS 2.07
I installed AVS 2.50
I replaced VirtualDub with VDubMod 1.4.13.1, and renamed it to VirtualDub.exe
I unzipped the AVS plugins, and told GKnot to use MPEG2DEC3.dll
Tried it out - got the "log file" error
Opened the AVS up in VDubMod, got the error that "decomb.dll" wasn't a AVS 2.5 plugin.
I went back to the AVS plugin ZIP, and pulled out MPEG2Dec3_094.dll from the decomb406b6 zip file. Altered the AVS to use that dll instead of the old decomb.
Tried it again, same thing happened - "log file" error, go into VDubMod, now it says that "MPEG2Dec3_094.dll" isn't an AVS 2.5 plugin. Ugh.
Went back to SourceForge page, downloaded the lastest prelease of VDubMod (VirtualDubMod_310103.zip), replaced the .EXE file with this newer one, got the same error again.

The video file is interlaced. Would that make the difference?

Any thoughts?

How about actually installing the correct version of Decomb.dll? You still seems to be using the original file that came with GKnot and that will not work. And also go back to mpeg2dec3.dll because no file originally included with GKnot will work with YV12.

@hakko504

Sorry, maybe I was too choppy in my first posting.

As far as I know, I did install the correct version of decomb.dll. I downloaded the AVS 2.5 plugins file, and tried both the "decomb.dll" and "MPEG2Dec3_094" that was included in it. (They were inside an internal zip file called decomb406b6.zip in the main file AviSynth_250_plugins.zip). I'm assuming these are the correct fiels for AVS 2.5 since they are from the AVS sourceforce page for AVS 2.5, but maybe that's a bad assumption. The HTML help file that comes with it says "Decomb Plugin for Avisynth; Version 4.06, for Avisynth 2.5). Is this still the wrong one? VDubMod is saying that it's not an AVS 2.5 file, even though the file itself says so (if you look at the version data).

Also, through all the trials I've instructed GKnot to use mpeg2dec3.dll, so I'm not sure what you mean by "go back to" it.

@dblue

I've read that thread several times trying to find help. Is there something specific that I'm missing there?

I think I just figured out what the problem was -

I kept getting that error set everytime I was attempting an encode where I cropped the movie with an odd number. If I set the four crop values to an even number, then it works, speed increase and all.

sorry to barge in on your Thread

but ive been trying to do exactly the same thing with no luck

im really new to avisynth and i dont really understand filters and what not

everthing works for me with AVI input but when i load in a d2v i get "not valid dvd2avi 1.76 file " help needed

refer to my thread above about stupid question but dont shout!!

also the colour spaces are swapped in the avi if i load avi as input i know there is the SwapUV() funtion but what exact syntax would i need if my clip was called C:\MATRIX\VIDEO_TS\matrix.d2v

thanks

everthing works for me with AVI input but when i load in a d2v i get "not valid dvd2avi 1.76 file " help needed

Gknot only compatible with DVD2AVI 1.76 but not the lastest version 1.77.

[jggimi]

"not valid dvd2avi 1.76 file " can also happen when you do use 1.76, if you move or delete the .vob files after creating the project. The .d2v file hard codes the .vob locations.

[jeremymacmull]

Hi and thanks for the replys

I was and still am using 1.76 i did not change the dvd2avi program when i installed avisynth 2.5 so i dont understand that neither did i move the original vobs etc any other ideas would be appreciated

thanks

the reason im so keen on Gknot with 2.5 is i have a p3 850 laptop so any speed increase is a big difference and when i got 2.5 manually working with vdubmod (not gknot ) i got 8 (yes 8 FPS) increase thats 50% for me so its definately worthwhile getting working

yay got the damn thing working

i followed the post above about not being a valid dvd2avi file and reripped the DVD as the person above tried and voila everything works

at least so far

yay

Okay everything works fine ive now ripped two dvds using the new avisynth but one question !

before with 2.07 when i clicked smart crop in gknot and it had values of
10
11 12
10

in the fields i could click compressibility check or encode and everything was fine.

but now i have to make sure that all the values are even numbers ie the 11 has to be a 10 or 12 otherwise it wont encode this means i often have to use pixel instead of smart crop mode. not really a problem just wanted to know why ?

Any ideas

I used VirtualdubMod with Gknot 0.27 and i works for me.

But the VirtualdubMod Jobs Control window is always present with the VirtualdubMod dubing window...

I would like to see single the VirtualdubMod dubing windows, like normally, what I make bad?

Thanks.

So, this is all cool, getting AVS2.5 working with GKnot - the one major gripe/problem I'm having is that 'colorspace' determined from DVD2AVI is being ignored. (This is normal according to the AVS 2.5 FAQ). But now I'm ending up with a bunch of dark movies since the information from the Luminance filter (Gain and Offset) aren't being used.

Do you guys know of any way around this then? I know I can use color plug-ins in the AVScript, but I'd like something like DVD2AVI where I can scroll from beginning to end of the movie to check the luminance before encoding. If I used a color plug-in in the script, I'd have to guess the gain and hope I chose the right value the first time, right? (or wrong?)

All help is appreciated!

[vorbis]

not to sound arrogant but if you're using avisynth 2.5 the colourspace is always gonna be yv12. I think the mpegsource 3 filter has some parameters that affect luma control.
A more general point though. GKnot is a great program but it wasn't designed for use with avisynth 2.5. It might be better to use a program that was i.e. dvx. that way you regain the automation that you get with using such programs.

Why don't you open the avs file in VdubMod. Use the script editor, add a line with ColorYUV(blabla), tweak it and preview it with F5.
