SMDeGrain

Okay, if the Vapoursynth Preview works fine the issue is probably not with the Vapoursynth script itself.

# Imports import os import sys import vapoursynth as vs core = vs.get_core() # Import scripts folder scriptPath = 'C:/Program Files/Hybrid/64bit/vsscripts' sys.path.append(os.path.abspath(scriptPath)) # Loading Plugins core.std.LoadPlugin(path="C:/Program Files/Hybrid/64bit/vsfilters/Support/libmvtools.dll") core.std.LoadPlugin(path="C:/Program Files/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/vslsmashsource.dll") # Import scripts import nnedi3_resample import mvsfunc import havsfunc # Loading C:\Users\takrayan\Downloads\ExtendedScenes.mkv using LWLibavSource clip = core.lsmas.LWLibavSource(source="C:/Users/takrayan/DOWNLO~1/EXTEND~1.MKV", format="YUV420P8", cache=0) # making sure input color matrix is set as 709 clip = core.resize.Point(clip, matrix_in_s="709") # Making sure input color range is set to TV (limited) range. clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1) # removing grain using SMDegrain clip = havsfunc.SMDegrain(input=clip, interlaced=False) # adjusting output color from: YUV420P8 to YUV420P10 for x265Model (i420) clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10) # Output clip.set_output()

(yes, script seems fine)
Do you see an error, when you call:

Inside a Windows command line prompt?

This is output:
