Good Denoiser filter for Anime... ?!

[SB4]

Hello,

I have an anime with a interlace and noise problems. I have fix interlace using QTGMC but i can't fix the noise using DeNoise. Any help with the noise. please ?!

I have use this script:

LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\dgdecode.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\mt_masktools.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveGrain.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\mvtools2.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\nnedi3.dll")
Import("C:\Program Files (x86)\AviSynth 2.5\plugins\QTGMC-3.32.avsi")
AviSource("test.avi")
QTGMC(Preset="Slow")
SelectEven()

McTemporalDenoise(). Use whatever preset you like. Or tune any of the settings yourself.

That clip should be inverse telecined, not QTMGC. Unfortunately, interlaced video was encoded with Xvid as if it was progressive so the chroma channels are screwed up.

AviSource("rTest.avi", audio=false) 
AssumeTFF()
TFM()
TDecimate()
McTemporalDenoise(settings="very high")

x264 mkv attached.

If that's too slow for you try TTempSmooth() at its stronger settings.

Just as a side note:

it's not recommended to place many files into Avisynth's default plugin folder;
FWIW, I have only four of them to be loaded automagically:

08/09/2012  01:36            59,904 ffavisynth.dll
01/27/2010  10:10            26,624 DirectShowSource.dll
07/05/2005  13:04             7,129 colors_rgb.avsi
07/19/2012  01:09                73 ffavisynth.avsi

The other ones remain inside an "AVSplugins" directory, and are called only when needed, of course

And it's not necessary to LoadPlugin() dll files, or Import() AVSI files, that are already in the plugins folder.

I have to load .dll files and import .avsi files manually because it dose not load automatically...

Thanks for the help guys...

[jagabo]

Make sure the plugin folder is set properly in the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\AviSynth\plugindir2_5

Thanks jagabo now it's work fine

I have one or two questions to ask. I want to upscale the video to 1024x600 and i have use the script below but the result i think need more sharpen and a little denoise. Is it right on i am wrong...?! How can i use eedi3 instead of nnedi3 ?

nnedi3_rpow2(2)
LanczosResize(1024,600)
Sharpen(0.3)

That would be the wrong aspect ratio. The video is 4:3 DAR so you should resize to 1024x768. I would try something like:

AviSource("rTest.avi", audio=false) 
AssumeTFF()
TFM()
TDecimate()
Deblock()
UnDot()
McTemporalDenoise(settings="very high")
LSFMod(strength=200)
nnedi3_rpow2(2, cshift="BicubicResize", fwidth=1024, fheight=768)

[SB4]

Ok, I do more test using NNEDI3 & aWarpSharp ( 2012.03.28 version ). Is this a good result or i used to much sharpen...?!

NNEDI3_rpow2(rfactor=2,cshift="lanczosresize",fwidth=1024,fheight=600)
aWarpSharp()

[SB4]

thanks jagabo i don't saw your post

[jagabo]

Yeah, I think awarpsharp() looks a little better. Also try going less sharp with nnedi3 (bilinear) and more with awarpsharp(). Or, since the video is sharper on the vertical axis than the horizontal axis (as with most video based sources), use a sharp resize for the horizontal, softer for the vertical:

nnedi3_rpow2(2)
LanczosResize(1024,960)
BilinearResize(1024,768)
aWarpSharp(depth=32)

I thought that looked better than the others I tried.

Consider using Stab() to reduce the projector bounce.

Thanks i realy appreciate your help

FrFun7 is good denoiser for anime. Also a line darkener like vmtoon - http://avisynth.org/mediawiki/External_filters#Linedarkening
