Patent When the Fleishers invented the rotoscope they opened a can of worms, starting a debate that continues to this day. Is motion capture really animation? When Ang Lee strapped sensors on himself to animate the model of the Hulk, was he creating animation? What about Waking Life? Was that a real cartoon or just a video effect? What about Don Bluth’s Anastasia ?

What’s the difference between closely studying referene video and actually tracing frame by frame? Does it depend on the ability of the animator? Does it need to be cartoony? Should it be smooth (on ones) or fast and clipped (on twos or threes)?

A can of worms indeed.
