Animation productions begin with the deciding on a story. The oral or literary source material must then be converted into an animation film script, from which the storyboard derives. The storyboard has an appearance somewhat similar to a comic book, and it shows the sequence of shots as consecutive sketches that also indicate transitions, camera angles and framing. The images allow the animation team to plan the flow of the plot and the composition of the imagery. The storyboard artists will have regular meetings with the director, and may have to redraw or "re-board" a sequence many times before it meets final approval.
The process of limited animation aims to reduce the overall number of drawings. Film is projected at 24 frames per second. For movements in normal speed, most animation in general is done "on twos," meaning each drawing is displayed twice, for a total of 12 drawings per 24 frames per second. Faster movements may demand animation "on ones" with a new drawing in each frame, while characters that do not move may be done with a single drawing (a "hold") for a certain amount of time. It is said[who?] that the Disney average was about 18 drawings per second, pretending that all characters of a scene share the same sheet of paper. Limited animation mainly reduces the number of inbetweens, the drawings between the keyframes which define a movement, and can cause stuttering if inbetweens are poorly set up.
Overall, the use of limited animation does not necessarily imply lower quality as it allows the use of many time-saving techniques that can improve the quality and flow of the keyframes and overall presentation of an animation.
