MClean + Vapoursynth does not work

[darkbyte]

Hybrid version: 2021.07.18.1 (Windows 10 64bit)
What did happen? Using the Vapoursynth frameserver, enabling MClean on the job yields a weird error.

Failed to evaluate the script: Python exception: No attribute with the name vcmod exists. Did you mistype a plugin namespace? Traceback (most recent call last):   File "src\cython\vapoursynth.pyx", line 2242, in vapoursynth.vpy_evaluateScript   File "src\cython\vapoursynth.pyx", line 2243, in vapoursynth.vpy_evaluateScript   File "D:\Hybrid\_temp\tempPreviewVapoursynthFile19_33_03_628.vpy", line 37, in <module>     clip = G41Fun.mClean(clip=clip)   File "C:\Hybrid\64bit\vsscripts\G41Fun.py", line 2517, in mClean     c = core.vcmod.Median(clip, plane=[0, 1, 1]) if chroma else clip   File "src\cython\vapoursynth.pyx", line 1891, in vapoursynth._CoreProxy.__getattr__   File "src\cython\vapoursynth.pyx", line 1754, in vapoursynth.Core.__getattr__ AttributeError: No attribute with the name vcmod exists.

As I've backtraced, vcmod is part of vcm.dll which I do have in c:\Hybrid\64bit\vsfilters\Support\vcm.dll and in the assembly vpy script I see it tries to load it:

# Imports import os import sys import ctypes # Loading Support Files Dllref = ctypes.windll.LoadLibrary("C:/Hybrid/64bit/vsfilters/Support/libfftw3-3.dll") import vapoursynth as vs # getting Vapoursynth core core = vs.core # Import scripts folder scriptPath = 'C:/Hybrid/64bit/vsscripts' sys.path.append(os.path.abspath(scriptPath)) # Loading Plugins core.std.LoadPlugin(path="C:/Hybrid/64bit/vsfilters/DebandFilter/Flash3kDeband/flash3kyuu_deband.dll") core.std.LoadPlugin(path="C:/Hybrid/64bit/vsfilters/SharpenFilter/AWarpSharp2/libawarpsharp2.dll") core.std.LoadPlugin(path="C:/Hybrid/64bit/vsfilters/Support/TCanny.dll") core.std.LoadPlugin(path="C:/Hybrid/64bit/vsfilters/Support/fmtconv.dll") core.std.LoadPlugin(path="C:/Hybrid/64bit/vsfilters/Support/libtemporalmedian.dll") core.std.LoadPlugin(path="C:/Hybrid/64bit/vsfilters/Support/vcm.dll") core.std.LoadPlugin(path="C:/Hybrid/64bit/vsfilters/Support/libmvtools.dll") core.std.LoadPlugin(path="C:/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/vslsmashsource.dll") # Import scripts import mvsfunc import muvsfunc import G41Fun # source: 'd:\Video\dvd\title_t00 (1)-004.mkv' # current color space: YUV420P8, bit depth: 8, resolution: 720x480, fps: 29.97, color matrix: 470bg, yuv luminance scale: limited, scanorder: progressive # Loading d:\Video\dvd\title_t00 (1)-004.mkv using LWLibavSource clip = core.lsmas.LWLibavSource(source="d:/Video/dvd/title_t00 (1)-004.mkv", format="YUV420P8", cache=0, prefer_hw=0) # making sure input color matrix is set as 470bg clip = core.resize.Point(clip, matrix_in_s="470bg",range_s="limited") # making sure frame rate is set to 29.970 clip = core.std.AssumeFPS(clip=clip, fpsnum=30000, fpsden=1001) # Setting color range to TV (limited) range. clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1) # denoising using mClean clip = G41Fun.mClean(clip=clip) # adjusting output color from: YUV420P16 to YUV420P10 for x265Model (i420@8) clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10, range_s="limited") # adjusted resizing to achieve PAR 1:1 for preview # resizing for preview to square pixel to 640x480 clip = core.resize.Bicubic(clip=clip, width=640, height=480) # set output frame rate to 29.970fps clip = core.std.AssumeFPS(clip=clip, fpsnum=30000, fpsden=1001) # Output clip.set_output()

I have no idea what is causing the issue.

I can reproduce the issue probably a typo somewhere.
Will report back.

Found the issue.
G41Fun was using the old vcmod not the newer vcm + a bug in the mClean script which always required mvfs.
-> will send you a link to a dev veriso which should fix the issue on ~10min.

I'd like to try the mClean filter on an old VHS capture, but I'm unable to locate it - any suggestions?

[Selur]

"Filtering->Vapoursynth->DeNoise->mClean" it's there you just have to scroll down, should be the 11th filter in the DeNoise-tab (unless I miscounted).
or "Filtering->Avisynth->DeNoise->Denoiser->mClean" (last in the drop-down)

[Miranda]

I'm also having problems running mClean and CAS but no luck. Any suggestions?

[Selur]

For some reason a color conversion is missing at the end of the script.
Your script ends with:

clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1) # adjusting color space from YUV422P10 to YUV444P8 for vsTemporalDegrain clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, range_s="limited") # removing grain using TemporalDegrain clip = havsfunc.TemporalDegrain(inpClip=clip, sigma=8.00, blockWidth=4, blockHeight=4, overlapWidth=8, overlapHeight=8, blockSize=4) # denoising using mClean clip = G41Fun.mClean(clip=clip) # contrast sharpening using CAS clip = core.cas.CAS(clip=clip) # set output frame rate to 25.000fps clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1) # Output clip.set_output()

but it should end with:

# adjusting color space from YUV422P10 to YUV444P8 for vsTemporalDegrain clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, range_s="limited") # removing grain using TemporalDegrain clip = havsfunc.TemporalDegrain(inpClip=clip) # denoising using mClean clip = G41Fun.mClean(clip=clip) # contrast sharpening using CAS clip = core.cas.CAS(clip=clip) # adjusting output color from: YUV444P16 to YUV422P10 for ProResModel clip = core.resize.Bicubic(clip=clip, format=vs.YUV422P10, range_s="limited") # set output frame rate to 25.000fps clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1) # Output clip.set_output()

Strange thing is, you are using the same verison I am.
But yours is missing the

# adjusting output color from: YUV444P16 to YUV422P10 for ProResModel clip = core.resize.Bicubic(clip=clip, format=vs.YUV422P10, range_s="limited")

My guess is that some update isn't triggered properly.
Can you write a step-by-step (really everything you do), since the way I try to reproduce this the script looks like it should.

It's strange because the file is already ProRes 422. I'll try it again and make notes for you.

[Selur]

It's strange because the file is already ProRes 422.

That doesn't matter since, TempDegrain doesn't support YUV422@10bit,...

[Selur]

Send you a link to my just updated dev to be sure we use the same version.
