Noise filter for anime?

[killerhis]

Hi.... there a lot of noise reductions filters out on the net. I have a anime movie and I want to apply 2d and 3d (noise)cleaning. The anime that I'm encoding is on DVD (Ghost in the shell), and want to encode it into XviD. It's a PAL 4:3 movie!
I've been playing around with some filters, but it's a though choise to choose the best.

So any ideas which 2d and 3d filter i need to use and it's options. Please post your ideas, suggestions and opinions here.

Thankz

PS: this is what i've got so far:

For a Ghost in the Shell I found this 2.5 script I used for a 1 CD XviD:
AFAIR the source was NTSC with Force Film.


MPEG2Source("C:\temp\rip05\ghost.d2v",cpu=4,idct=2)
crop(8,16,-8,-16)
Convolution3d (preset="animeHQ")
dup(threshold=1.5,copy=true, blend=true)
converttoyuy2()
msharpen()
converttoyv12()
bicubicresize(624,352)
limiter()


Be sure to try using the latest Dup (http://forum.doom9.org/showthread.php?s=&threadid=44500&highlight=Dup+CNR2).

EDIT by neuron2: That is, Dup version 2.20 beta 1 from the end of the thread. This version was contributed by the great sh0dan and fixes a blending problem as well as provides low-level optimizations.

that's a good setting if you are using the beta avisynth 2.5
for 2.0 users u mite want to look into using the following setting


Telecide(post=true).Decimate(cycle=5)
SmoothHiQ(3,20,30,256,0)
TemporalSmoother(3)
Dup(threshold=0.50,show=false,copy=true)
LanczosResize(640,360,16,0,688,480)


don't use telecide if the source is pal of course =p
Dup needs to be played with though, some encode well at 0.5 threshold while some need as much as 1.0.
Lanczos is not necessary, but gives better looks to edges. You can also use a BicubicResize
The resize needs to be tweated to your source.
The example above is for a letterboxed source.

note that I don't use C3D as it does not support smart edge detection, like that of SShiQ does. But either way, _do_not_ place the SmoothHiQ below the TemporalSmoother under _any_ circumstances.

Ghost in the Shell PAL is also interlaced. SO i guess you should definitely put telecide in your script

[MasterYoshidino]

just don't decimate frames =)

@MasterYoshidino: Actually you do not gain anything from the "smart edge detection" when using radius = 3. Do the math, and you will see that no pixels can be blocked. ;)

I find that marc fd's atc (alternate temp cleaner) cleans up noise better than avs temporalcleaner, because it has the pixel lock feature.
