Pulling my hair out, cannot get any encodes to start.

The Vapoursynth script itself looks fine to me:

but the encoding call:

fails with:

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

which indicates a problem with the decoding.

Vapoursynth problems might be due to a bug in the Vapoursynth script, a problem with reading or decoding the source or something totally different.

-> Basically the same request as before: Check the Vapoursynth Preview.
