Can you tell me how to do the "setup Vapoursynth environment" step or point to a tutorial on how to do it?
Also, thank you very much for attention.
An update to the situation, I made the Hybrid's ffmpeg hidden and created a link to my system's one, ffmpeg -> /usr/bin/ffmpeg
Now with Hybrid using the system one the encoding worked, I hope the results are the same they would be with the Hybrid version.
Regarding version, here is a '-version' output from both:

So I guess it solved the issue, at least for the video I'm testing, which is the one in the link, I will now test for the whole batch.
Edit: One thing to notice is that, the system version is about 350KB and the Hybrid version is 50MB.
The version Hybrid uses is statically linked, thus it includes all the dependencies, the version in your system is not.
