Hybrid Erroe if use vapoursynth filters

[Selur]

Does the Vapoursynth preview work or does it throw an error?

The used script seems to be fine, might be some problem with the source and the source filter or the encoding call:

Do you get any errors when you call that call inside a Windows Command Prompt?
I hope your machine supports ' --asm avx512' because that definitly was added by you. (You also might want to make sure you use an up-to-date x265 release because they released a few avx512 related fixes since I build x265 for Hybrid.)

might also be a Memory leak in one of the filters, since the scripts memory usage seems to be increasing and increasing. (After 250frames I'm already at 2600MB RAM usage, in case that keeps up you might be running low on RAM.)
Try Disabling 'Filtering->Vapoursynth->Misc->Input->Prefer LWLibAVSource over FFMpegSource2' and see whether that helps.
