View Full Version : A good result filtering. How do I get the same?

Hi!

I have a dvd source - noisy anime. To filter I useRemoveGrain(mode=5)
FFT3DFilter(bw=32,bh=32,bt=3,ow=16,oh=16) #fft3dgpu()
super=MSuper(pel=2, sharp=1)
backward_vec2 = MAnalyse(super, isb = true, delta = 2, overlap=4)
backward_vec1 = MAnalyse(super, isb = true, delta = 1, overlap=4)
forward_vec1 = MAnalyse(super, isb = false, delta = 1, overlap=4)
forward_vec2 = MAnalyse(super, isb = false, delta = 2, overlap=4)
MDegrain2(super, backward_vec1,forward_vec1,backward_vec2,forward_vec2,thSAD=330)
LSFmod(defaults="slow",dest_x=640,dest_y=480)
#EdgeCleaner(smode=1,strength=24)
fastlinedarkenmod(strength=55)
Gradfun2dbmod()
I compared its results with the segment of the video used in the music video. My picture looks much worse: it is more noisy and has less detail. I especially do not like the way looks arm-blade. In the screenshot №3 it looks great.
How can I try to get similar results filtering?

1)Source - screenshot (http://images.netbynet.ru/img.php?caa8ad01ad91851bf97894a8619d4554.png), fragment of the video (http://www.mediafire.com/?748muy8le4489aa#2)(crop+resize).
2)My picture. (http://images.netbynet.ru/img.php?466e6d1767de5ee7200693724786207c.png)
3)Great picture. (http://images.netbynet.ru/img.php?2c9fa137c2f3854a8e676382b5196646.png)

By posting a sample, of course.

In that screencap the chroma plane looks to be a lot more denoised(or blurred) than that of the luma plane.

By posting a sample, of course.Do you mean that I need to add a fragment of video exactly 720x480? I'll do anything, just tell me what exactly. ;) But about 54 hours I am deprived of the ability to upload pictures and a video (because of changes in my internet connection).

Sample: Unprocessed video of the original source. 30 seconds to 1 minute. Use DGIndex to demux the video into an m2v.

It (http://www.mediafire.com/?mmnntfymu5l1jnt) is completely intact fragment.

A somewhat more presentable image:

MPEG2Source("D:\test.d2v", cpu=4)
animeivtc(mode=3,aa=4)
Deblock_QED()
source = last
vectors = source.MVAnalyseMulti(refframes=2, pel=2, overlap=4, sharp=1, idx=1)
source.MVDegrainMulti(vectors,thSAD=800,idx=1)
HQDering()
LimitedSharpenFaster(ss_x=1.8, ss_y=1.8, smode=3, strength=185, overshoot=1, undershoot=1)
crop( 4, 0, -4, 0)

and if you're a masochist for hating grain, then add dfttest() after HQDering and you'll remove just about all the grain there is, and you'll also blur quite a bit as a side effect.

Nightshiver, Motenai Yoda,
:thanks:
