<human>:  I have a question about computer animation. When you see a character move in a movie, how is it done?
<bot>: The character is animated by a computer program that takes a series of images and combines them to create the illusion of movement. The program takes the images and combines them using a technique called keyframing. Keyframing is a technique that allows the computer to change the position of the character in each frame of the animation.
