[HELP] Export fails w/ Vapoursynth de-interlacing

[Selur]

1. Check the Vapoursynth Preview, it should show an error message.
2. Looking at the used script:

# Imports
import vapoursynth as vs
# getting Vapoursynth core
import sys
import os
core = vs.core
# Import scripts folder
scriptPath = '/usr/lib/python3.10/site-packages/'
sys.path.insert(0, os.path.abspath(scriptPath))
# Import scripts
import qtgmc
import validate
# Source: '/home/jonah/Desktop/VIDEO/HVR/00_0001_0000-00-00_000000.DV'
# Current color space: YUV411P8, bit depth: 8, resolution: 720x480, frame rate: 29.97fps, scanorder: bottom field first, yuv luminance scale: limited, matrix: 470bg, format: DV
# Loading /home/jonah/Desktop/VIDEO/HVR/00_0001_0000-00-00_000000.DV using LWLibavSource
clip = core.lsmas.LWLibavSource(source="/home/jonah/Desktop/VIDEO/HVR/00_0001_0000-00-00_000000.DV", format="YUV411P8", stream_index=0, cache=0, fpsnum=30000, fpsden=1001, prefer_hw=0)
frame = clip.get_frame(0)
# setting color matrix to 470bg.
clip = core.std.SetFrameProps(clip, _Matrix=vs.MATRIX_BT470_BG)
# setting color transfer (vs.TRANSFER_BT601), if it is not set.
if validate.transferIsInvalid(clip):
  clip = core.std.SetFrameProps(clip=clip, _Transfer=vs.TRANSFER_BT601)
# setting color primaries info (to vs.PRIMARIES_BT470_BG), if it is not set.
if validate.primariesIsInvalid(clip):
  clip = core.std.SetFrameProps(clip=clip, _Primaries=vs.PRIMARIES_BT470_BG)
# setting color range to TV (limited) range.
clip = core.std.SetFrameProps(clip=clip, _ColorRange=vs.RANGE_LIMITED)
# making sure frame rate is set to 29.97fps
clip = core.std.AssumeFPS(clip=clip, fpsnum=30000, fpsden=1001)
# making sure the detected scan type is set (detected: bottom field first)
clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_BOTTOM) # bff
# adjusting color space from YUV411P8 to YUV444P16 for vsQTGMC
clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P16, range_s="limited")
# Deinterlacing using QTGMC
clip = qtgmc.QTGMC(Input=clip, Preset="Slow", TFF=False, opencl=True) # new fps: 59.94
# Making sure content is preceived as frame based
clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive
# adjusting output color from: YUV444P16 to YUV422P10 for ProResModel
clip = core.resize.Bicubic(clip=clip, format=vs.YUV422P10, range_s="limited", dither_type="error_diffusion")
# set output frame rate to 59.94fps (progressive)
clip = core.std.AssumeFPS(clip=clip, fpsnum=60000, fpsden=1001)
# output
clip.set_output()

The script looks fine. Atm. it's using LWLibavSource, maybe try using a different source filter like Bestsource or FFmpegSource2.
