i see. the blurring and strange oddities are quite ai like. is an interpolation script not machine generated?
Here's the tool we used: https://github.com/hzwer/ECCV2022-RIFE. The only interpolation artifact I'm aware of is the pattern on the MC's outfit — since it's a fairly basic technology, it just blends the two frames and the pattern gets lost. Other things that might seem odd to you could be due to the two drawings being drawn differently from each other.
