It supports many Avisynth and Vapoursynth filters, including a few that do motion interpolation, if you have used SVP before it is based on an Avisynth plugin called InterFrame, the Vapoursynth filter "Interframe/SVP" in Hybrid is the same thing.
This are the settings I normally use.
Alternatively, SVP also has a program to convert a video to 60 fps called SVPcode, which is far easier to use, but Hybrid is far more complex and is what I would recommend having tried both.
