I have some sort of interference that causes darkish horizontal lines in my captures. I have to use very heavy smoothing in my caps and the best spatial smoother I've found to do this is Smart Smoother. Here's the script I'm using
Code:
#==============================================#
# -= AviSynth script by MovieStacker v1.1.1 =- #
#==============================================#

import("c:\encoding\functions.h")

AviSource("D:\CAPTURE.AVI",false)
trim(445,161651)
FieldDeinterlace()
BicubicResize(320, 208, 1/3, 1/3, 0, 6, 352, 468)
ConvertToRGB()
VD_SmartSmoother(5,125,false)
ConvertToYUY2()
BlockBuster(method="noise", detail_max=100, variance=2, seed=1)
AddBorders(16, 16, 16, 16)
LegalClip()

###########################################
# Smart Smoother by Donald Graft, v1.1	  #
#					  #
# diameter (3-11, odd),	threshold (1-200)      #
###########################################

function VD_SmartSmoother(clip clip, int "diameter", int "threshold", bool "interlaced")
{
  LoadVirtualdubPlugin("C:\encoding"+"\smooth.vdf", "_VD_SmartSmoother")
  return clip._VD_SmartSmoother(default(diameter,5), default(threshold,25),
    \  default(interlaced,false)?1:0)
}
I like Smart Smoother a lot! It seems reasonably fast too. Anyone else use that one- or anyone know of a better noise filter for really strong smoothing?

thx,
ren

hey zTr,

Thanks for those links. Looks like HiQ is the one I need to try next It's cpu optimized too

For super noisey captures - PixeDust (or even golddust) combined with TemporalCleaner imho are the absolute best!

However, they are very slow! I've just tried Convolution3d (preset="animeBQ") with temporalcleaner and the results were very good and a lot faster. worth a try.

Peach has some very nasty bugs in it. It has a habit of leaving object stationary when they should be slowly moving. Sometimes mouths son't even look like they open whilst people talk.

If the noise is periodic bars at a given frequency you could try the Wavelet NR for VDub.
