Beginners Guide To Ripping With Gordian Knot

apologies for that, the old went down again before i could smuggle the latest db and lock the forums for migration.

Could someone please give me some advice on how best to clean up this rain type effect (film scratches?) without blurring too much. MCTemporalDenoise does a nice job but some of the stronger vertical lines remain.

Small sample here

elguaxo

I'll take a look at the sample tomorrow, but in many filters (FFT3D, DFTest, MVAnalyse/MVDegrain) you can define a block width and height. Bigger blocks denoise more and smaller blocks less. Instead of using a square block you could use a much bigger width and maybe that will have a stronger impact on the vertical scratches.

In similar cases I've seen that the scratches are "temporal stable" and motion compensated denoisers can't do too much about them. Try with FFT3D or DFTest first. I'll report my findings tomorrow.

junkboy

Thanks for taking the time to look at the sample elguaxo

, in the mean time I'll have a play with the block sizes in FFT3Dfilter and I've not used DFTest before so will download and read-up on it and give it a try also.

EDIT: DFTest is a typo, yeah? I couldn't find it (just references to it) but I found dfttest if that's the right one.

RedVeil

dfttest is the right one: Discrete Fourier transform "test" :wink:

junkboy

Yeah, thanks RV but I've figured that out since then

Wow, what a load of gobbledygook that wiki page is

MCTemporalDenoise(settings="low")

OK, I put them all in (what a huge list, I have never put so many filters into my script before), but I get two errors:

- GK says it can't load Variableblur.dll, but that filter is in the right folder with all the other plugins, so I don't know what I'm doing wrong there.
- GK also says there's a syntax error in Deblock_QED.avs, in line 2 column 1. How to fix that?

There are a LOT of settings to fiddle with in MCTemporalDenoise, but for now I'd just try out the 5 default "settings" (very low, low, medium, high and very high - If you want to see what's different in each of the defaults, they are described in the MCTemporalDenoise.avs).

Sorry for asking n00b questions, but how do I put settings like that in the script? If I want medium, how do I let GK know?

Your posted script was a great help so far, thanks!

junkboy

As you'll only be using the 5 global settings in MCTemporalDenoise, then you don't need to load the VariableBlur filter (it's only used if you want to change the sharpening mode in LSFmod). I can't tell you why it won't load though - Double checking that the LoadPlugin line in the script is correct is the only thing I can suggest if you want to get it to load.

You've used the Deblock_QED function before (back on page 24), so I'm not sure why you're getting a syntax error now. The avs of it you've got is this one, yeah?

And if you want to try the medium setting in MCTemporalDenoise, just replace the "loW" that I used in the example, with "medium". Like this...

MCTemporalDenoise(settings="medium")

elguaxo

A small note: MCTemporalDenoise's medium setting is quite strong. Most of the time you'll get away with very low or low.

Slayer

Meh, I downloaded that Deblock avs you linked (it'a different one), but it gives me the same syntax error: line 2, column 1.

@ elguaxo: I'll use low.

elguaxo

If you need more than low, then before switching to medium you can try:

MCTemporalDenoise(settings="low",chroma=true,stabilize=true,edgeclean=true)

Slayer

OK, I got Deblock running OK now, I put the wrong path there :oops:

Now I get the following error:

"Script error: there is no function named FFT3Dfilter"

While I have installed fft3dgpu0.8.2.exe in both AviSynth plugins folders I have, and I have

LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\FFT3dGPU.dll")

in my script. Any ideas?

telmoMRC

for the FFT3Dfilter work properly you have too send fftw3.dll to your \WINDOWS\system32\ folder that is if your SO is x32

also if you are runing whit x64 you have to send that to \WINDOWS\SysWOW64\ folder

http://g.imagehost.org/download/0778/fftw3win32

i hope this will fix you problem :beerchug:

Slayer

OK, downloaded your file, extracted it into sys32 folder, pasted the dll directly into the folder. Then called upon it in my script, but it says

"fftw3.dll is not a plugin for Avisynth"

So I'm calling it the wrong way. How should I call or load it?

junkboy

You don't load the fftw3.dll in your script, so just remove that LoadPlugin line and you should be good to go.

You renamed your load plugin... its gotta be fft3dfilter.dll & not fftw3.dll :wink:

I remember having this exact same problem when ripping KFVK with that nasty deblock script :mrgreen:

junkboy

wtf are you on about? He didn't rename anything :prat:

Edit: BadBugs edited his post and changed who he quoted, though it doesn't make much difference :roll:

elchupacabra

FFT3DFilter uses the so called fast fourier transformation. The guy who wrote the filter didn't want to write his own fast fourier transformation routines and thus his plugin relies on a third party DLL fftw3.dll. fftw3.dll is not an AviSynth plugin, but a DLL with functions used by FFT3DFilter. You only have to load FFT3DFilter, which will then try to automatically load fftw3.dll from one of your directories listed in the PATH environment variable. The PATH environment variable always includes your Windows system directory. So the easiest solution is to simply copy fftw3.dll into your Windows system folder. I hope it is clear now.

Slayer

Aaagghh, this is driving me crazy!!

Thanks guys, for being so helpful, but it is still not working. This time I get the following error:

"There is no function called FFT3Dfilter" and then the path of the MCTemporalDenoise script follows ("C:\Program Files\etc...)

I have in my system32 folder the following:

FFT3dGPU.dll (this was the first fft3d file I downloaded)
fftw3.dll (this is the one Telmo posted)
fftw3d.dll (this is a copy of Telmo's file, with the d added in the name)

So, once again: what to do? Remember, the reward is gonna be a very crappy Dutch horrormovie, so you know it won't be in vain! :wink:

telmoMRC

you have to send this files to AviSynth plugin folder http://h.imagehost.org/download/0350/fft3dfilter

here is my path

LoadPlugin("C:\Program Files (x86)\GordianKnot\AviSynthPlugins\FFT3dGPU.dll")
LoadPlugin("C:\Program Files (x86)\GordianKnot\AviSynthPlugins\FFT3DFilter.dll")

and if you do this fftw3.dll to your \WINDOWS\system32\ folder should work fine

you´r path should be something like this

LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\FFT3dGPU.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\FFT3DFilter.dll")

i hope this will help you
