Comments.Text: The technique is called rotoscoping.  You can search for many ways to speed up or automate rotoscoping.  But in general it is a labor-intensive process.

Comments.Text: After effects and other compositing packages have tools which make this easier (roto-brush in AE for one example). They work a bit like the magic wand in Potatoshop. They're not perfect, but they would probably work fairly well on Anime with its flat colours and hard edges.
