This may appear to "work" but I doubt it is better than a 300K FPS camera by any means. It will not work perfectly across all scenes, it cannot interpolate uncommon movements and finally, it cannot interpolate many low-res cases like 5-20 FPS where there is actually significant missing information across frames.

That interpolates look to me significantly worse in case of highly volatile volume affecting reactions, like the ballon and the the immediate jelly post-impact sequence with the racket. There a clearly still hard limits to what you can believably hallucinate without knowledge of the higher frequency processes that have not representation in the source material and are to chaotic to be learned from watching random 240fps videos for training.

Also for a research output the ground-truth real slomo vs. super slomo is missing to make a proper quality assessment. The paper itself only list some fairly low-frequency inbetween frames as reference for comparison with other methods.
