does see fine.

Encoding call, also looks fine:

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.

Output 0 frames in 4.00 seconds (0.00 fps)

y4m [info]: 1920x1080p 1:1 @ 24000/1001 fps (cfr)

x264 [info]: using SAR=1/1

x264 [info]: profile High, level 5.0, 4:2:0, 8-bit

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?
