This is already highly, highly relevant for 2d animation. Many complex moves (especially dancing) are filmed in video first, then the movement is traced over by hand. This is called Rotoscoping. This is basically auto-rotoscoping, and I expect it to see commercial usage within popular high budget projects within 2 years. Previously, even the highest budget anime couldn't really afford 2d dance scenes due to the insane drawings required.

As I recall, Ralph Bakshi used this to mixed effect back in the 70s with The Lord of The Rings animated films.

Rotoscoping is directly tracing from film frame by frame. Most of the time animators instead use what are called reference key poses. For extremely stylized characters it can be difficult if not impossible to use rotoscoping for complex sequences because the proportions make the motions impossible. Instead specific frames where there's resting motion in the sequence are pulled, and the animators translate the positions of the joints to the unusual silhouette of the character for the key frames. The Castlevania and Masters Of The Universe: Revelation series from Netflix use this quite a bit for realistic characters -- it was heavily used during the Trevor and Death fight and Skelegod versus Savage He-Man fight -- and Rise Of The Teenage Mutant Ninja Turtles and High Guardian Spice used it for their stylized characters for perspective and fight scenes. If this technology can instead be used to not only find the key poses but also roughly determine the inbetweens for a heavily stylized character like Rocko Wallaby or Blossom, Bubbles, and Buttercup then it is extremely useful.
