traditional animation is much harder than today's style of animation. it often uses a stop-motion camera to "liven", or animate, the photos made by the producer. when movie-makers use stop-motion, they need to draw one picture for every scene. however, there are tools to help save time with movie-making. other types of animation, such as limited or digital animation, can also be used now. fps is the number of times a movie is shot in one second.
