SkyGo gives an error when Hybrid is running.

I don't think the 'Always use Vapoursynth' option was available back then.
But Vapoursynth itself was.
iirc. under Filtering in the lower right corner you could switch between Avisynth and Vapoursynth and noXSynth.
For testing you could switch to Vapoursynth and then in the Vapoursynth-Tab enable a filter like Color-Tweak.

I did notice that on the bottom right, but its already set to "Vapoursynth".. I tried enabling Color-Tweak and started an encode and SkyGo errored immediately.

When I looked in TaskManager, I can see that ffdmpeg is still a sub-task, so I don't think this changed anything.
