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.
