does see fine.

Encoding call, also looks fine:
[code]"C:\Program Files\Hybrid\64bit\Vapoursynth\vspipe.exe" "C:\Users\Michael\AppData\Local\Temp\encodingTempSynthSkript_2021-10-09@19_37_17_8510.vpy" - --y4m | "C:\Program Files\Hybrid\64bit\x264.exe" --preset slow --crf 24.00 --profile high --sync-lookahead 18 --psy-rd 1.00:0.15 --sar 1:1 --qpfile "C:\Users\Michael\AppData\Local\Temp\Scenes From a Marriage S01E01_2021-10-09@19_37_17_8510_05.qp" --deblock -1:-1 --non-deterministic --range tv --colormatrix bt709 --demuxer y4m --input-range tv --fps 24000/1001 --output-depth 8 --output "C:\Users\Michael\AppData\Local\Temp\2021-10-09@19_37_17_8510_06.264" -
but directly aborts. :/

What happens if you call the encoding call inside a 'Windows Command Prompt'-window?
Does the Vapoursynth Preview work properly or does is show an error with you settings?
