[HELP] Resizing Question

[Selur]

encoding call looks correct:

"C:\Program Files\Hybrid\64bit\Vapoursynth\vspipe.exe" "C:\Users\Administrator\AppData\Local\Temp\encodingTempSynthSkript_2021-08-07@01_38_01_7410.vpy" - --y4m |  "C:\Program Files\Hybrid\64bit\ffmpeg.exe" -y -noautorotate -nostdin -threads 4 -f yuv4mpegpipe -i - -an -sn -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p10le -strict -1 -vsync 0 -vcodec ffv1 -coder 0 -context 0 -g 1 -level 1 -metadata encoding_tool="Hybrid 2021.08.06.1" "C:\Users\Administrator\AppData\Local\Temp\1917 (2019)_new_2021-08-07@01_38_01_7410_02.mkv"

but aborts with:

[yuv4mpegpipe @ 00000000004b9180] Header too large.

Vapoursynth script looks correct to me:

# Import scripts folder

Does the Vapoursynth Preview work correctly?

I did try to reproduce the issue here using:

# Imports
import os
import sys
import vapoursynth as vs
# getting Vapoursynth core
core = vs.core
# Import scripts folder
scriptPath = 'I:/workspace/Hybrid/debug/64bit/vsscripts'
sys.path.append(os.path.abspath(scriptPath))
# Loading Plugins
core.std.LoadPlugin(path="I:/workspace/Hybrid/debug/64bit/vsfilters/DenoiseFilter/TTempSmooth/TTempSmooth.dll")
core.std.LoadPlugin(path="I:/workspace/Hybrid/debug/64bit/vsfilters/Support/fmtconv.dll")
core.std.LoadPlugin(path="I:/workspace/Hybrid/debug/64bit/vsfilters/ColorFilter/ToneMap/tonemap.dll")
core.std.LoadPlugin(path="I:/workspace/Hybrid/debug/64bit/vsfilters/SourceFilter/LSmashSource/vslsmashsource.dll")
# Import scripts

# current color space: YUV420P10, bit depth: 10, resolution: 3840x2160, fps: 25, color matrix: 2020ncl, yuv luminance scale: limited, scanorder: progressive
# Loading G:\TestClips&Co\files\HDR\HDR10\4K sun HDR test.mp4 using LibavSMASHSource
clip = core.lsmas.LibavSMASHSource(source="G:/TestClips&Co/files/HDR/HDR10/4K sun HDR test.mp4")
# making sure input color matrix is set as 2020ncl
clip = core.resize.Bicubic(clip, matrix_in_s="2020ncl",range_s="limited")
# making sure frame rate is set to 25
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# Setting color range to TV (limited) range.
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)
# color adjustment using ToneMap
clip = core.resize.Bilinear(clip=clip, format=vs.RGBS, range_in_s="limited", matrix_in_s="2020ncl", primaries_in_s="2020", primaries_s="2020", transfer_in_s="st2084", transfer_s="linear",dither_type="none", nominal_luminance=1000)
clip = core.tonemap.Mobius(clip=clip)
clip = core.resize.Bilinear(clip=clip, format=vs.YUV420P8, matrix_s="709", primaries_s="709",range_s="limited", transfer_s="709", transfer_in_s="linear", range_in_s="limited", dither_type="ordered")
# denoising using TTempSmooth
clip =  core.ttmpsm.TTempSmooth(clip=clip)
# Resizing: 3840x2160 -> 1920x1080
clip = muvsfunc.SSIM_downsample(clip=clip, w=1920, h=1080, smooth=1, use_fmtc=True, gamma=False, fulls=False, fulld=False)
clip= core.resize.Bicubic(clip=clip, format=vs.YUV420P8)
# adjusting output color from: YUV420P8 to YUV420P10 for x265Model
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10, range_s="limited")
# set output frame rate to 25.000fps
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# Output
clip.set_output()

(should be similar encough to spot errors)
-> couldn't reproduce the problem.

Okay, one issue I spotted, the output of your vapoursynth script isn't YUV420P10 but YUV420P8, but that's not causing the crash.
-> looking into it

Ps.: As a side note: I would usually move Tweak below ToneMap.
