Well I started a thread a while ago and even made a website about noise reduction in anime(in my signature). Its long outdated and I would like to share with eveyrone my, I soppose, "new and improved" filter set.
Now, I have a dual 1900+ MP processer system, so I can process video very fast with multiple very slow filters being used, so this filter set is not for the..under 1500Mhz crowd.
If one takes a DVD through DVD2AVI through avisynth(decomb and resize and such) then into virtualdub, one can add these filters to drastically reduce noise reduction and clean up edges and overall video sequnce, and make an encoding that has the possiblity to look better than the DVD. Now every source differs...but I would venture to say, that this can be used for practically anything from low noise to high noise just because of the way the filters work internally
And here it is:, in order. Everything is defualt settings unless specified:
1. 2-d cleaner optimized for speed (choose which vdf to use for Intel or AMD users): Threshold 3 or 4.
Use threshold 3 for less detail smoothed, or 4 for slightly more. I usually use 4 on anime and 3 on real movies. So Try 4 first.
2. Smart Smoother HQ (Klaus Post) v1.2: Amount anywhere from 125-200. 200 is a good number, but depending on source you may want to use less.
3. Warpsharp = 10 or less
With these three filters in series with the defualt settings except for what is listed above, this will clean up an anime source like you wouldn't beleive.
Now I usually encode to an uncompressed avi (usually huffyYUV .avi) first because with all of these setings(while resizing, iVTCing, and frameserving from RGB into YUV color space) I can only process around 7-10fps, even on a dual 1900+. So when you are doign SVCD mulripass or DIvX 2-pass encoding(DivX3 or DivX5) it is usually beneficial to do so.
You can also do these same settings all in avisynth by using the vdub_filters.avs from donald graft I think, and setting the commands up like this:
convertToRGB()
VD_2DCleaneroptk7(4,2,2)
VD_SmartSmoothHiQ(5,50,200,"weighted")
VD_WarpSharp(10)
ConvertToYUY2()
Well have fun with my new findings and start making BETTER ANIME!!!
