Timing for Animation has been one of the pillars of animation since it was first published in 1981. Now this 40th anniversary edition captures the focus of the original and enhances this new edition with fresh images, techniques, and advice from world-renowned animators. Not only does the text explore timing in traditional animation, but also timing in digital works.

Vibrant illustrations and clear directions line the pages to help depict the various methods and procedures to bring your animation to life. Examples include timing for digital production, digital storyboarding in 2D, digital storyboarding in 3D, and the use of After Effects, as well as interactive games, television, animals, and more. Learn how animated scenes should be arranged in relation to each other, how much space should be used, and how long each drawing should be shown for maximum dramatic effect.

All you need to breathe life into your animation is at your fingertips with Timing for Animation.

Authors

Harold Whitaker was a BAFTA-nominated professional animator and educator for 40 years; many of his students number among today's most outstanding animation artists.

John Halas, known as "The father of British animation" and formerly of Halas & Batchelor Animation Studio, produced more than 2, 000 animation films, including the legendary Animal Farm (1954) and the award-winning Dilemma (1981). He was also the founder and president of the International Animated Film Association (ASIFA) and former Chairman of the British Federation of Film Societies.

Tom Sito is Professor of Animation at the University of Southern California and has written numerous books and articles on animation. Tom's screen credits include Shrek (2001) and the Disney classics Who Framed Roger Rabbit (1988), The Little Mermaid (1989), Beauty and the Beast (1991), Aladdin (1992), and The Lion King (1994). In 1998, Tom was named by Animation Magazine as one of the 100 Most Important People in Animation.

Timing to Suggest Weight and Force—1

Each part of the body moves as a result of the action of muscles, or as a result of the movement of another part of the body to which it is attached. For instance in Fig. 33A, when the arm is raised, the upper arm tends to be raised first by the shoulder muscles. As the elbow is a flexible joint, there is a time lag before the forearm starts to move and similarly another time lag before the hand moves.

FIG 33A Raising an arm, showing effect of flexible joints. B In a walk the flexible ankle joint results in the foot (railing downward as the ankle goes up on drawings 2 and 3, and trailing upward as the ankle goes down on drawings 5 and 6. C The sequence of events when a man pulls on a rope. On drawing 2 he takes up the slack, on 3 he starts to move his body weight backward, and on 4 he leans back on the rope. D When the rope itself is jerked, the man’s arms are drawn forward until they are in a straight line with the rope. At this point his shoulders are pulled forward in drawing 3 and in 4 and 5 his whole body is dragged away.

In a walk, the knee is a hinge joint and the ankle acts almost like a ball and socket joint. If the angle between the shin and the foot is kept the same, the ankle joint appears to be rigid, so this angle must vary. In Fig. 33B the foot starts on the ground (position 1) and is lifted forward for the step. The knee is raised, but the foot tends to hang back and so comes up heel first. The toe trails downward until the top of the movement (position 4), but as the leg straightens the foot tends to keep going up and so, as the heel goes down, the foot rotates until the heel hits the ground (positions 5 and 6). The foot now tends to continue its downward movement but as it is stopped by the ground it quickly slaps down flat.

If, as in Fig. 33C, a character is to give a strong pull on a rope, the first part of the body to move is probably the hips, followed by the shoulders, the arms, and finally by the rope. The amount of movement depends on the strength of the character, the weight on the other end of the rope, and the mood of the scene, but the order in which different parts of the movement take place is the same.

If, in the same situation, the character is being pulled by a force at the other end of the rope, as in Fig. 33D, then the order of events is reversed. First the rope moves, then the arm, the shoulders, and the hips. The first part of the pull takes up the slack in the rope, and if the movement is fast, the shoulders do not move until the rope and the arms have been pulled into a straight line. At this point the shoulders jerk forward and the character tends to pull out into a straight line as he goes out of screen. In a slow, steady pull the character may have time to react and try to resist.

To give the impression that a character is wielding a heavy hammer it is important to time the movement carefully.

The start position is as Fig. 34-1. The man is relaxed with the hammer head resting on the peg which he is going to hit. To start the movement he lifts the hammer. If it is heavy, he cannot do this in the position shown in Fig. 34-1A as he would then be off-balance and would topple over. In order to transfer the weight of the hammer over his feet so that he is balanced, he must step forward and grasp the hammer near its head (Fig. 34-2). He can now slide the hammer toward himself and lift it above his widely spaced feet (Fig. 34-3). As the head of the hammer rises above shoulder level, he starts to move its weight backward in preparation for the forward action. However he cannot let it go too far behind him or he would overbalance backward (Fig. 34-4). So he starts to move his body weight forward, and this eventually starts the hammerhead moving forward (Fig. 34-5). He jerks his body forward and downward to give a forward impetus (Fig. 34-6) and the job is done. Now he need only step back and the hammer will fall and hit the peg. This position links up to Fig. 34-1 or at least Fig. 34-2.

FIG 34To make the hammer look heavy, the man must keep the weight of the hammerhead more or less balanced above his feet, until he hits the ground with it. Only a light hammer could be lifted, as in 1A, without the man falling over.

Timing to Suggest Weight and Force—3

In an energetic, repeated movement, for example, a man hitting something with a pitchfork, the different parts of the figure move in a particular way to give the maximum feeling of effort (Fig. 35).

Drawing 1 shows the impact of the pitchfork with the ground. The end of the pitchfork remains in contact with the ground for drawings 2–4, while the body begins to move out of the extreme position in readiness for the next stroke. The shoulders arrive at their furthest backward position in drawing 7 and begin to move forward again in drawing 8, although the head of the pitchfork is still moving backward. In drawing 9, the hips move quickly backward as the shoulders and arms come forward and downward, leaving a big gap between the position of the pitchfork in this drawing and that in drawing 1 to give a final impact to the movement. Note how the curvature of the body changes from convex to concave by means of “S” curves on drawings 2 and 7.

FIG 35The man is repeatedly hitting something on the ground with a pitchfork. Note how the weight of the body is maneuvered to get the maximum effort into the impact on drawing 1.

Timing to Suggest Weight and Force—4

An athlete is going to lift the heavy bar bell. He starts confidently, and in drawing 17 is anticipating grabbing the bar. He grabs the bar on 25, and 31 is the anticipation to the first attempted lift. He is still confident but grits his teeth somewhat as he makes the effort, as shown in drawing 37. The bar bell does not move. After 37 he comes to a puzzled hold as he realizes he has a more difficult problem than he thought. In drawing 57 he makes a much bigger jerk after making a more determined and annoyed anticipation in drawing 51. After this jerk he manages to lift the bar bell with great difficulty. A few frames after drawing 65 he collapses out of screen under the weight.

FIG 36On drawing 17 the Roman athlete confidently prepares to lift the heavy bar bell. He anticipates on drawing 31 and tries to lift on drawing 37. The weight does not move so he makes a much bigger anticipation on drawing 51 and a big jerk on drawing 57, which enables him to get the weight up in the air on drawing 65, before collapsing with exhaustion.

Timing to Suggest Force: Repeat Action

In a repetitive to and fro action such as sawing, it is not sufficient to draw the forward and backward extremes and then in-between them. To convey the feeling of effort being put into the action ...
