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?

Here's the message

Code:
x264 [error]: No input file. Run x264 --help for a list of options.

Error: Failed to retrieve frame 0 with error: Resize error: Resize error 3074: no path between colorspaces (2/2/2 => 1/2/2). May need to specify additional colorspace parameters.
Output 0 frames in 3.82 seconds (0.00 fps)

What about the preview?

Quote:x264 [error]: No input file. Run x264 --help for a list of options.

should only happen if you forgot the last ' - ' at the end.

Quote:Error: Failed to retrieve frame 0 with error: Resize error: Resize error 3074: no path between colorspaces (2/2/2 => 1/2/2). May need to specify additional colorspace parameters.

is probably a problem with the Vapoursynth script

Sorry, didn't think that was part of it

Code:
Error: Failed to retrieve frame 0 with error: Resize error: Resize error 3074: no path between colorspaces (2/2/2 => 1/2/2). May need to specify additional colorspace parameters.

Preview is a grey box

Edit: Woops I just noticed I left 'level' as unrestricted, I'm changing it to 4.1

Problem is related to Neo-fft3d, with it disabled handling works fine.
Seems like it does some color space conversion I was not aware of.
-> looking into it.
(no, not neo-fft3d, but the subtitle adding)

Send you a link to a dev verison which hopefully fixes the issue.

New error!
This one is with MCDegrainSharp

Does the Vapoursynth Preview show an error?
