Mostly samples from anime, but one from a more Western looking example as well.
It’s not perfect. The reviewer’s own samples failed miserably, such as a Totoro head turn, and zoom out of someone watching fireworks.
But for coloring a fully sketched sequence from one fully colored frame, or generating wave splashes, flying hair and flapping clothes, wow.
We’re already restricted by what animators have time to animate. This could definitely lead to fewer scenes of paper dolls bobbing up and down to represent walking. There’s plenty of low-hanging fruit prime for some uplift in anime already.
I also posted about this a few days ago.
