Fighting colorbanding?

[asarian]

Looking at the output of some rendered scenes (x264 output), I just realize what I really need is a filter like GradFun2DBmod for VapourSynth, or the DitherTools, as I'm gettting too much unwanted colorbanding.

I couldn't find anything like that for VapourSynth? Does it exist even?!

Thanks.

This has native VS support.

^^ Thanks. ;) That looks very promising!

Alas, F3kdb doesn't appear to be 64-bit. ( I should have mentioned I was looking for a 64-bit debander.

It's available in both x86 and x64 for AviSynth and VapourSynth. All the binaries can be found here (https://www.nmm-hd.org/newbbs/viewtopic.php?f=7&t=239) (VapourSynth is the 2.0 release).

Well, YOU probably can. :) Me? Did a lot of compiling in FreeBSD, but in Windows I generally just click.

I was planning on installing Visual Studio 2015 as it is, so this might be a good first project.

You can find f3kdb binaries here also: https://www.nmm-hd.org/newbbs/viewtopic.php?t=1590

No 64-bit binaries, though. (At least, I don't see them. It's a Japanese site, though, so it's hard to tell). Keep getting this error (from the f3kdb_2.0pre2 package):

The three links people linked to you all of them contain 64bit binaries, two in Chinese and one in English.

The error is telling you the name of the function your are calling does not exist, it should be:

vid = core.f3kdb.Deband(vid)

Okay, thx. :)

In my defense, I took that line straight off the test.vpy included with the package:

import vapoursynth as vs
import sys

core = vs.Core()
core.std.LoadPlugin(r"D:\Microsoft Visual Studio 10.0\Projects\ffms2_src\build-msvc\Win32\Release\ffms2.dll")
core.std.LoadPlugin(r"D:\Dropbox\Projects\flash3kyuu_deband\Debug\flash3kyuu_deband.dll")
core.std.LoadPlugin(r"D:\VapourSynth\filters\histogram.dll")

last = core.ffms2.Source(r"E:\torrent\20100228 pokemon ranger.mp4")
last = core.f3kdb.F3kdb(last, y=49, output_depth=10, dither_algo=2)[:10]
# last = core.hist.Luma(last)

last.output(sys.stdout, y4m=True)

Nice file location. :D

[asarian]

Works great! :)

Any chance we'll ever see KNLMeansCL support on F3kdb for the 'opt' paramater?

[Leinad4Mind]

I was hoping to see GradFun3 for vapoursynth. Since I wanted a Ordered Dither. Does flash3kyuu_deband do ordered dither, or it works like GradFun2DBmod?

clip = core.f3kdb.Deband(clip, dither_algo=2)You should read the documentation before asking questions about a plugin.

Thanks! I just didnt had time today to check that. But thanks a lot for the quick reply. I'll put encoding and compare with gradfun3 on avisynth. Hope to be similar result. :)
