Ah, I forgot to update the script,..

(updated to Vapoursynth R57 RC1 in the dev builds.)
-> will send you a new version in a few minutes.

Send you a verison with updated script, check the Vapoursynth Preview before encoding,..
That worked.
Audio encoding is pretty slow and only uses 10% CPU - I don't know if that's normal or a bug.
That's normal and not Hybrids fault.
Enabling "Jobs->Queue->Parallel subjob processing" will tell Hybrid to run subjobs that are not interfering or depending on one another in parallel helps a bit wiht the general subjob processing , but won't speed up the subjobs itself.
