Upscaling by x-factor

Yes, Hybrid does not have extensive scripting support.
Since it does not really make sense for it. Hybrid is a GUI meant for encoding, not filter comparisons.

For filter comparisons, better create the Vapoursynth scripts yourself using the scripting/programming language of your choice.
I do not play to write some sort of API interface for Hybrid, since it's not a library but an encoding GUI.
