Winner:
(not yet decided) It is up for discussion as to what video has the best smoothness to artifact ratio, it can be subjective so i will let majority decide.
Test Scenario
In this test I recorded at 60fps with chat & scoreboard enabled. I have also used the BuildUHC kit, as it has the most variety in items and animations, to provide a worst-case scenario and give the interpolation a good stress test.
I have interpolated with rife at 2x, 3x, 4x, and 6x, and interpolated the rest to 1440 FPS with different SVP algorithms tested. 1440 FPS works best here as all of these different inputs and combinations are factors of 1440.
