MCTemporalDenoise [v1.4.20 - Update 2010/07/02]

[ankurs]

from another thread of mine : http://forum.doom9.org/showpost.php?...51&postcount=4

any idea why ?

LaTo,

You're re-introducing a lot of unnecessary noise with your MCsharpen routine. You really should do a minblur before the difference blur. Like this:

pshrp = last
pmax  = source.MT_Logic(bw1,"max").MT_Logic(fw1,"max")
pmin  = source.MT_Logic(bw1,"min").MT_Logic(fw1,"min")

rg11d = MT_MakeDiff(pshrp,pshrp.RemoveGrain(12,-1))
MT_MakeDiff(pshrp,pshrp.RemoveGrain(4,-1))
MT_LUTxy(rg11d,last,"x 128 - y 128 - * 0 < 128 x 128 - abs y 128 - abs < x y ? ?")
MT_MakeDiff(pshrp,last)
MT_MakeDiff(last,last.RemoveGrain(12,-1))
MT_LUTxy(pshrp,last,"y 128 - 1.5 * x +",chroma="copy first")

#mt_lutxy(last,last.removegrain(11,-1), "x y == x x x y - abs 16 / 1 2 / ^ 16 * "+string(strength)+" * x y - 2 ^ x y - 2 ^ "+string(strength)+" 100 * 25 / + / * x y - x y - abs / * + ?", U=2, V=2)

MT_Clamp(last,pmax,pmin,0,0,chroma="copy first")

The commented out line is what you have currently.

i would like to add your Udegrain script to automkv, so first of all i will ask permission to include

No problem

light = Udegrain(settings="light")
heavy = Udegrain(settings="heavy")


After you only need to tweak the radius...

The old mode is always here, the 2 method are different... So don't expect the same result between these.

Is this function suited to interlaced DV video?

yes, just set interlaced=true

[Soulhunter]

Nice function! :]

Any chance of modifying this to work with the new fork of MVTools?

I'm trying this function with the following code

loadplugin("c:\program files\avisynth 2.5\plugins\mvtools.dll")

AviSource("c:\temp\x.avi")

ConvertToYV12()
UDegrain(settings="light",interlaced=true)

and it gives me the following error:
"MergeChroma:Images must have same with and height".

If I don't use the switch "interlaced=true" there's no error.

The fix is in v8.08c, redownload this version

Yes, why not, but only when it will be stable because at this time many changes occurs each week...

[LaTo]

v9.01a:
changed some default settings
added modX(=blocksize) checking
added adapt & SS for sharpening
added dering option (dering, DRGrad, DRGthr, RGmode)
added flat areas processing (flat, AGstr, GFthr, bias)
updated documentation in .avsi


All (new) options are documented in the .avsi

[Adub]

Sweet! I'll get to looking at this thing right away!

Looks great, thanks for the effort. Have to test it some time, when get time.

[Alain2]

Really like this script (v8.08b), very effective and kills less details than a mvdegrain alone
Will try the new version as well

[LaTo]

v0.9.05a:
changed version number: vX.XX branch -> v0.X.XX branch
added AA options (AA,useEEDI2,maxd,AAthr,method)
changed dering --> edgeclean: you can now use your own script (see docs)
fix bug with show=true
fix bug with chroma in PP stage
fix omission with chroma=false in MVanalyse
changed some settings
added changelog in .avsi

[Adub]

Man, this thing is just getting better and better!! I can't wait to play around with this. And with AA added as well!!

Woohoo, keep up the awesome work LaTo!!

[mozzle]

Yea, thanks a lot Lato. I'm starting to get the hang of tweaking this and getting some nice results. I've noticed very good detail retention.

[LaTo]

v1.0beta:
changed name Udegrain --> MCTemporalDenoise (to be more specific and avoid confusion with chroma)
added the choice to use MVDegrain instead of MVCompensate+TTempSmooth (since the chroma bug in MVDegrain is fixed)
added twopass option to do the denoising job in two stage (very effective but slow)
added MT parameter for MVTools (be careful +- unstable)
added fixFFT3D parameter to prevent banding/posterize with limit=-1
added stabilize options (stabilize,maxr,TTstr)
added deblock options (deblock,useQED,quant1,quant2)
added new presets "light"(=low)/"heavy"(=medium) --> 5 presets (very high is 'a bit' extrem)
added check/warning for some settings
added thSAD2 & limit2 parameters for twopass=true
added overrange parameter for controling sharpness (useful for sharpening more than the source)
changed +- much code to implement twopass/MVdegrain/MT, should be bug free (I hope)
changed sharp->MVsharp & post->sharp
changed "light Smode4" --> LimitedSharpenFaster for sharp=2 (strength,Smode,soft,overshoot)
reduce max radius to 6
optimize chroma in PP stage (+20% with all PP on)
fix a bug with external p clip
fix a bug in Star&Bright Point Protection with maxdiff>0
added YV12&MOD16 restriction
changed some settings due to new presets
restriction when using MT=true: bt=1 in FFT3Dgpu & plane=4 in MVDegrainMulti (will be removed when fixed)


Finish... 47ko -> 81ko, it's a big update

I wait after your comments/suggestions/improvements

[Didée]

I played a bit with it ... not bad, really not bad! A couple of points came up, but I'll need some time to describe them (have to do sth else right now). Will post a bit later about that.
