Cleaning Filters

[Angelyco]

I'm still learning a lot about different cleaning filters and I've managed to get by so far, and I have read the ErMaC guide many many times, but the cleaning filters section always trips me up. I have a hard time trying to match my footage up to the pictures used in the guide to figure out what filters I should be using. Right now I'm working with Grave of the Fireflies and it's the oldest source I've used so far, so it needs a bit of work.



My biggest concern is the static-y stuff all over the image and how to get rid of it. If you could recommend any other cleaning filters I could use for this as well, I would greatly appreciate it!

try removegrain()
modes 2 and 5 should be the first ones you try, after that I'm not sure (the documentation should go over what modes do what and how well they do it)
try v1 pre-release if you don't already have it

The pages of Scintilla's Guide to AVISynth Postprocessing Filters for AMVs that deal with smoothers go over some smoothers that should work well to remove film grain (DeGrainMedian and RemoveGrain come to mind). You'll also want something to deal with all those rainbows; derainbowers should usually come *before* any IVTC operations.

Interesting, I didn't see any rainbowing until you mentioned it.

Thanks for the input guys, I'll try some of these and post my results.

Okay, here is what I came up with:

Code: Select all

DeGrainMedian()
DeRainbow(10)
aWarpSharp(depth=22.0)
Tweak(hue=0.0, sat=1.3, bright=2, cont=1.2, coring=true, sse=false)

It looks a lot better, but there is still some noise/grain that I'm not sure if I should use another filter as well or what settings I should use in DeGrainMedian, the settings in the guide don't make much sense to me. DeRainbow didn't make much of a difference from what I could see (trying it with and without the filter).

try these ones and post back on how it looked
BlindPP(quant=3,cpu=4,moderate_h=13,moderate_v=25)
ttempsmooth()
ColorYUV(gain_u=4, gain_v=-2)
FastLineDarken(strength=150,luma_cap=225,thinning=0)
Tweak(cont=1.1,sat=1.2,bright=-4, hue=0)
RemoveGrainHD()
Toon(strength=0.05)

[Angelyco]

I don't have the FastLineDarken and RemoveGrainHD filters right now and I had to get my video done somewhat of a hurry. I will definitely hang onto this script since I will probably be using this anime in the future.

Thanks!

np and yes those are some great settings for the avisynth script i used those settings on almost all the amv's i have done just depends on the anime i will move some tweaks around but the way it is there will work for must of all of them if u can't find the pulgins for the removegrain hd and fastlinedarken and toon let me know
