In storytelling, the timing of ideas and actions is important to the audience’s understanding of the story at any point in time. It is important that the animation be timed to stay either slightly ahead of the audience’s understanding of what’s going on with the story, or slightly behind. It makes the story much more interesting than staying even with the audience. If the animation is too far ahead, the audience will be confused; if the animation is too far behind, the audience, will get bored; in either case, their attention will wander.
