ALMOST everything is done by computer. Disney is making shorts now in the classic format, “Enchanted” had 14 minutes of 2D animation by the great James Baxter and team, and “Princess and the Frog” that is coming out Christmas of 2009 will be classically animated. Eric Goldberg is leading that animation effort.
Is the “tweening” being done by hand or just the key frame animation?
And even by the early 1990s Disney animation was no longer fluid, the motion/frame rate was too fast on some movements.
