GradFun2DBmod [v1.5 - Update 2009/12/30] - Page 4

Hi LaTo, thanks for this wonderful script, my first time using it, need your suggestion. Here is small clip of source, I have tried with

MCTemporalDenoise(settings="medium")
GradFun2DBmod()

What will be your suggestion here?

GradFun2DBmod is integrated in MCTemporalDenoise, so you should see "enhance" option instead (faster)...

kool · 28th January 2010, 12:53

ah, That is why my encoding was slow

. Would you suggest to use MCTemporalDenoise(settings="medium") and I will get GradFun2DBmod to work with defaults, or I should touch any params?

If I want to make some changes to GradFun2DBmod, how I would do that with MCTemporalDenoise, and what are the most important param to play with?

Thanks in advance.

Thanks in advance.

It's in the .avsi of MCTemporalDenoise:

Code:

### +---------+
### | ENHANCE |
### +---------+-----------------------------------------------------------------------------------------------------------------------------------------------------------+
### | enhance : Enable GradFun2DBmod post processing to enhance flat areas (may avoid banding & blocking when encoding too)                                               |
### | GFthr   : Gradfun2db threshold [1.0=off,...]                                                                                                                        |
### | AGstr   : AddGrain strength  [0.0=off,...]                                                                                                                          |
### | bias    : Brightness bias for adaptative grain mask (the higher, the less grain in dark areas & the more grain in bright areas) [-1=off,0=input,1...254,255=invert] |
### | temp    : Temporal stabilization for grain (the higher, the more calm) [0=nervous,...,100=static]                                                                   |

One year since last post, but I think it might be for good on the filter.

Its actually 2 things. Im having some ghosting problems on an anime source. Its in the sides of black strokes in a fast motion scene, I discarded mask, radius,mode.... I can upload example if you want.
The second one is more a petition, since this dither is going to be encoded in some way, it will mostly convert into annoying blocking. Maybe it could better fit a film grain type of noise rather than the actual small random pixels, but I know that that doesn't depend on you since gradfun calls addgrain, but maybe adding the grain size parameter could help.

egrimisu · 12th February 2011, 01:35

why addgrain and not grainfactroy3? grainfactory seems more nice.

Dogway · 12th February 2011, 16:44

my bad, I just discovered grainfactory3 in the first page

Im trying to pass it through mask=true, does it work?

SilaSurfer · 12th February 2011, 17:01

With mask=true you are dihtering parts where there is susceptibility that banding will occur. Why use GrainFactory's silver grain affect only in those areas, when in my opinion should be used in whole picture since it really fools your eyes that there is more detail in it.

Dogway · 12th February 2011, 18:46

Why bother dithering if compression will band it again? Answer would be, use a better/different dithering or use a better/different compressor. Well, at the moment I'm looking at the first, to use grainfactory for dithering, since my target is grain free anime.

Nekomander · 25th April 2011, 07:36

any suggestion/s with this? the source itself has banding issues.

source: here or here

Vitaliy Gorbatenko · 26th April 2011, 03:48

Source practically perfect. Nothing you can do with it.

Nekomander · 27th April 2011, 04:51

if you look closely (bottom right) theres banding. i just can't figure out a way to get rid of it without taking away too much details.

Vitaliy Gorbatenko · 27th April 2011, 11:52

You want to disguise the noise using for this? By smoothing you get nothing, when coding, since color space contains only 8 bits.

Nekomander · 27th April 2011, 13:03

i just want to remove the artifact and have a result from this>

to this>

Vitaliy Gorbatenko · 28th April 2011, 05:45

Then you need to store videos in lossless format. I'll say it again - can not save the video in h264 or divx and have the picture without this artifact. All you can do - to mask its noise and no more.

cretindesalpes · 28th April 2011, 12:46

The picture is perfectly colorbanding-free in YV12 colorspace. The culprit is the final YUV to RGB converter in your player. See the difference:

Code:

AVCSource ("00005.dga")
Interleave (ConvertToRGB24 ().Subtitle ("ConvertToRGB24"),
\           yv12torgb24hq () .Subtitle ("yv12torgb24hq"))

To achieve a better result, all you have to do is just adding a bit of noise. This will smooth the steps created by the RGB conversion.

Code:

AddGrainC (var=1.2, uvar=1.2)

If adding noise makes your encode too big or too noisy, try this instead:

Code:

GradFun3 (thr=0.35, ampo=2.0)

Edit : typo

Nekomander · 29th April 2011, 07:11

true. switched back to my usual renderer (madvr) and it was flawless, not so with evr custom. thanks for the script/s

hey guys,i'm trying to use this script, but can't make Megui to load it. everytime it says that "Object reference is not set to an instance of an object"

the script that i use is:

#denoise
#Trim
Trim(420, 8361) ++ Trim(10160, 21338) ++ Trim(23137, 48371) ++ Trim(50170, 50768)

ConvertToYV12()

#Debanding
Import("C:\Program Files (x86)\AviSynth 2.5\plugins\GradFun2DBmod.v1.5.avsi")
GradFun2DBmod(thr=3,str=0,mask=false)

and the plugins directory from avisynth looks like this
