Looking for Vapoursynth filter alternatives/ports for some Avisynth filters

[Selur]

Hi, I'm trying more and more to get rid of Avisynth and switch to Vapoursynth, but for some filters/scripts in Avisynth I really haven't found any alternatives/ports.
Does anyone know ports for:

• AutoAdjust (https://forum.doom9.org/showthread.php?t=167573)
• SmoothLevels/SmoothCurve (https://forum.doom9.org/showthread.php?t=154971)
• HDR AGC (https://forum.doom9.org/showthread.php?t=93571)
• ChannelMixer (http://avisynth.nl/index.php/ChannelMixer)
• amDCT (https://sites.google.com/site/amdctfilter/)
• MosquitoNR (https://forum.doom9.org/showthread.php?t=167582)
• Camcorder color denoiser (this is a VirtualDub filter) -> slow, but working port: https://github.com/DomBito/VapourSynth-CCD
• Checkmate (http://avisynth.nl/index.php/Checkmate)
• DeStripe (https://forum.doom9.org/showthread.php?t=154863)
• DeScratch (http://avisynth.org.ru/descratch/descratch.html)

I know some of these filters/scripts are rather old, but I use them from time to time and would prefer not to having Avisynth just for these few.

Ps.: Note that I loading a Avisynth filter in Vapoursynth isn't really an options since I'm often using Linux (which is why Vapoursynth is really interesting) and I haven't found a way to get it working without running Vapoursynth and Avisynth with Wine (which isn't really stable; or in a VM).

Hello.

I have vapoursynth x64 portable and cannot find a compatible HDR AGC (or perhaps AutoAdjust if it did a similar thing).

How did you go ? If you could not find something, what did you use instead ?

[Selur]

Sorry, but at least afaik there are no ports or alternatives to AutoAdjust, SmoothLevels/SmoothCurve, HDR AGC.
On sources where I really need them I use Avisynth.

SmoothLevels is in havsfunc.py

You can use curves in Y, Cb,Cr or R,G,B curves with vapoursynth curve

Channelmixer variations should be possible with ShufflePlanes and Expr , but it would be nice if someone wrote a helper function

[Selur]

SmoothLevels is in havsfunc.py

@poisondeathray: thanks for the info!

Okay, the SmoothLevels is not that good, due to:
- 'SmoothLevels: Ecurve=0 is unusable at the moment due to missing sin operator in Expr' when Lmode != 0 or protect -1
- no 'show' parameter

Tried ChannelMixer for vapoursynth, following wiki calculations for pixel, but RGB values does not match avisynths ChannelMixer() output. Is that right? Not sure why.

import vapoursynth as vs
from vapoursynth import core

def channel_mixer(rgb, RR=100.0, RG=0.0,   RB=0.0,
                       GR=0.0,   GG=100.0, GB=0.0,
                       BR=0.0,   BG=0.0,   BB=100.0):
    """
    example for pixel calculations:
    R=146
    G=36
    B=44
    print('new R =', round(0.01*RR*R + 0.01*RG*R + 0.01*RB*R,  0))
    print('new G =', round(0.01*GR*G + 0.01*GG*G + 0.01*GB*G,  0))
    print('new B =', round(0.01*BR*B + 0.01*BG*B + 0.01*BB*B,  0))
    """
    
    if not rgb.format.color_family == vs.RGB:
        raise ValueError('channel_mixer: input clip must be RGB color_family')
    
    planes = [core.std.ShufflePlanes(rgb, planes=p,  colorfamily=vs.GRAY)  for p in [0,1,2]]
    R = core.std.Expr(planes[0], expr = f'0.01 {RR} * x * 0.01 {RG} * x * + 0.01 {RB} * x * +')
    G = core.std.Expr(planes[1], expr = f'0.01 {GR} * x * 0.01 {GG} * x * + 0.01 {GB} * x * +')
    B = core.std.Expr(planes[2], expr = f'0.01 {BR} * x * 0.01 {BG} * x * + 0.01 {BB} * x * +')
    return core.std.ShufflePlanes([R,G,B], planes=[0,0,0], colorfamily = vs.RGB)

clip = core.avisource.AVISource("video.avi")
rgb = core.resize.Point(clip, format=vs.RGB24, matrix_in_s = '170m') #it could be any RGB even float RGBS
clip_out = channel_mixer(rgb, RR=100.0, RG=20.0, RB=-5.0, GR=0.0, GG=100.0, GB=0.0, BR=-20.0, BG=0.0, BB=100.0)
clip_out.set_output()

Thanks !

Any news on descratch and especially deflicker ?
