[Vapoursynth] Grain plugin doesn't seem to be working

[hihflappy]

I'm trying to use my script I usually use for things, this script always worked without fail but I get this error now:

Failed to evaluate the script:
Python exception: No attribute with the name grain exists. Did you mistype a plugin namespace?

Traceback (most recent call last):

My script being this:

import vapoursynth as vs
import lvsfunc as lvf
import kagefunc as kgf
import vsTAAmbk as taa
import fvsfunc as fvf
import havsfunc as haf
import functools
import cooldegrain
from vsutil import *
from nnedi3_rpow2 import *
core = vs.core

src = lvf.src(r'E:\VideoWork\tst.mkv')
src = src[20336:20373]
src = fvf.Depth(src, 16)

scaled = core.resize.Spline36(src, 854, 480, matrix_in_s="709", matrix_s="170m")

aamask = kgf.retinex_edgemask(scaled).std.Binarize(12000).std.Inflate()
aa = taa.TAAmbk(scaled, aatype='Nnedi3', mclip=aamask)
dehalo = haf.HQDeringmod(aa, darkthr=0, sharp=0, mthr=50)

dark_mask = kgf.adaptive_grain(scaled, show_mask=True, luma_scaling=12).std.Binarize()
lineart_mask = kgf.retinex_edgemask(scaled, 1).std.Maximum().std.Binarize()
deband_mask = core.std.Expr([dark_mask, lineart_mask], expr='x y -', format=vs.GRAY)

deband_a = core.f3kdb.Deband(dehalo, range=13, y=28, cb=16, cr=16, grainy=12, grainc=0, output_depth=16)
deband_b = core.f3kdb.Deband(dehalo, range=15, y=28, cb=32, cr=32, grainy=16, grainc=0, output_depth=16)
deband = core.std.MaskedMerge(deband_a, deband_b, deband_mask)
grain = kgf.adaptive_grain(deband, 0.2, luma_scaling=12)

out = grain
final = fvf.Depth(out, 10)
final.set_output()

I initially updated to R57 a few days ago but I encountered an error saying this with the same script:

Failed to evaluate the script:
Python exception: module 'vapoursynth' has no attribute 'YCOCG'

if clip.format.color_family not in (vs.YUV, vs.YCOCG, vs.GRAY):
AttributeError: module 'vapoursynth' has no attribute 'YCOCG'

So I went to downgrade back to R54 but I now have the grain error. How would this be fixed? Any help is appreciated

No attribute with the name grain exists. Did you mistype a plugin namespace?

-> seems like you are missing: https://github.com/HomeOfVapourSynthEvolution/VapourSynth-AddGrain

AttributeError: module 'vapoursynth' has no attribute 'YCOCG'

Yup, YCOCG and COMPAT got removed.

I still have the error on R54 even with the grain plugin added. And that's a shame about by YCOCG.

[_Al_]

navigate to vsutil.py and delete that vs.YCOCG with that comma in:

if clip.format.color_family not in (vs.YUV, vs.YCOCG, vs.GRAY):

check if there is more of that in that script,
also, not that is wrong, but:

from vsutil import *
from nnedi3_rpow2 import *

is dumping a lots of functions unmarked on a pile, because if having more modules loaded like that, you loose readability, you do not know what function is from what module

[_Al_]

kagefunc.py is using this function error, it says it is in this line:

grained = core.grain.Add(clip, var=strength, constant=static)

so looking at that kagefunc.py script:

def adaptive_grain(clip: vs.VideoNode, strength=0.25, static=True, luma_scaling=12, show_mask=False) -> vs.VideoNode:
    """
    Generates grain based on frame and pixel brightness. Details can be found here:
    https://kageru.moe/blog/article/adaptivegrain
    Strength is the strength of the grain generated by AddGrain, static=True for static grain, luma_scaling
    manipulates the grain alpha curve. Higher values will generate less grain (especially in brighter scenes),
    while lower values will generate more grain, even in brighter scenes.
    """
    mask = core.adg.Mask(clip.std.PlaneStats(), luma_scaling)
    grained = core.grain.Add(clip, var=strength, constant=static)
    if get_depth(clip) != 8:
        mask = fvf.Depth(mask, bits=get_depth(clip))
    if show_mask:
        return mask

    return core.std.MaskedMerge(clip, grained, mask)

those pages does not seam to have a link for downloads, but here: https://git.kageru.moe/kageru/adaptivegrain/releases , that might be his adaptive grain

Thanks for the help, AL. I will give these a shot again tomorrow. I do actually have that adaptive grain plugin downloaded in my plugins64 folder though, so I don't think it's that unless that is the wrong place to put it but that's where it always was before when this script was working fine without issue until now

[Selur]

In older version of Vapoursynth the grain filter did come bundled with Vapoursynth, with API4 and R55+ most of the bundled filters were removed so you have to download them seperately.

I'm sorry for the very late reply but that indeed work, thank you very much
