[HELP] Encoding error when trying to deinterlace and denoise DVD MKV video to x264

Yes, it does.

Vapoursynth script seems fine to me:

but, the encoding call:

aborts with:

y4m [error]: bad sequence header magic
x264 [error]: could not open input file `-'

So it seems to be an issue with the Vapoursynth script or setup.
Broken Hybrid installation (too old version updated with newer one) or a parallel installed Python or Vapoursynth could be the cause of a broken Vapoursynth setup.
-> Does the Vapoursynth Preview show any errors?
