View Full Version : Need suggestions for removing lots of grain from video...

I need suggestions on how to clear up most of the video noise from the recently released Golgo 13 collection. Here are two screenshots. Basically, every frame looks like this (grainy).

And here is a video sample link (16 mb): http://www.megaupload.com/?d=QK3N9P1O

The script I'm using at the moment. Still incomplete.

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\DGDecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\decomb.dll")
MPEG2Source("C:\Users\Sage Nagashi\Desktop\Project X\VTS_04_1.d2v")
Crop(4,0,-4,0,true)
TFM().TDecimate()
RemoveGrain(Mode=17)
MSharpen(15,100,true,false,false)
Tweak(sat=1.2)
LanczosResize(640,480)

Maybe you should use FFT3DGPU filter with settings like this
FFT3DGPU(plane=0, sigma1=0.1, sigma1=0.1, sigma1=2.0, sigma1=4.0) with fine tuning of sigma3 and sigma4.
And don't forget to look in which channels the grain is
to process luma and chroma noise separately.
Or use some animation-related filter like from MSU.

I think you got a little confused, Chabb :)


FFT3DGPU(plane=0, sigma1=0.1, sigma1=0.1, sigma1=2.0, sigma1=4.0)

makes no sense :)


FFT3DGPU(plane=0, sigma1=0.1, sigma2=0.1, sigma3=2.0, sigma4=4.0)

is what you meant, right?

Also play with setting mode to 4 (process both chroma and luma), instead of the default - 0 (process luma only)

Play with DFTTest also, and if you can spare the time... MDegrain2 ;)

I can't see any grain there at all - but I do see terrible, terrible video compression.
FFT3DGPU will at least smooth over it.
