12 Principles of Animation + 12 More!

Yea.... 12 more!

Thanks to Jeremy Cantor for adding 12 more principles of animation to the original 12 by Frank Thomas and Ollie Johnston. It's more like the icing on the cake and putting a few cherries on top of it. The extra 12 are especially helpful for CG animation, so check 'em out!

I haven't added anything to it, and I'm simply copy-pasting it from this page, so that we don't lose this gold if the site goes down or whatever. And also, thanks to a friend Mustafa Lazkani for pointing this out to me.

Here are the 24 (12 + 12) principles of Animation! ..................

The 12 (er...24) fundamental principles of animation (updated 06/28/03)
(As partially listed in "Disney Animation - The Illusion of Life" by Frank Thomas & Ollie Johnston)

Jeremy Cantor – Animation Supervisor – Sony Pictures Imageworks - May 4th, 2002

1. Squash & Stretch: Organic objects tend to have some degree of malleability. When forces act upon them they will deform appropriately depending on the nature, direction & degree of the forces. When applying squash & stretch in your animations, it is important to remember that, if volume is not maintained, your object will appear to be expanding or contracting. If you squash a tennis ball vertically, it should simultaneously widen horizontally. Squash & Stretch can also be applied to rigid, articulated structures. When the structure compresses, certain joints will rotate off to the side. When you drop from a standing position into a squat, your hips move down while your knees move sideways. Your legs can be said to be squashing and stretching, even though the individual joints are not compressing or expanding.

2. Anticipation: The setup before the main action. It lets the audience know that something is about to happen. For instance: reaching behind you with your fist before delivering a punch. A boxer tries to avoid anticipation (telegraphing) when throwing a jab.

3. Staging & Composition: The clear presentation of an idea. What is the story being told? What is the best way to tell this story? What are the appropriate camera angles & screen direction? Is the flow of the scene guiding the viewer’s eyes as intended? Are your poses strong? If you arbitrarily “freeze-frame”, will the resulting still-image be a well-composed work of art? Do the elements of your scene work together visually? Are your object’s trajectories too linear? Or perhaps too complex? Are important elements of your scene hidden behind less important elements?

4. Straight Ahead Action vs Pose to Pose: Two methods of animating. Straight ahead involves stepping through the individual frames of your scene & manipulating them sequentially. Pose to pose involves defining the extremes and then filling in the spaces inbetween. Stop motion can only be done via Straight Ahead. Cel animation can be done either way. Straight ahead usually requires more pre-planning.

5. Follow Through & Overlapping Action: Follow through is the extension of a main action. For instance, the continuation of a tennis-stroke after the ball contact. Follow-through is also evident when a secondary appendage (tail, antenna) is indirectly driven by the primary motion of the body. Follow-through will occur later than the main action because the force dictating the main action takes longer to reach the appendages. When an object in motion changes direction, stops accelerating or stops completely, secondary parts of that object will continue in the original direction after the change in the main force. A woman's dress fluffing forward after she stops walking. A ponytail bouncing in an "S" motion when someone jumps up and down. Follow-through is often reduced if an appendage has (and uses) its own muscles. When a cat runs, the muscles of its tail often tighten to reduce follow-through & maintain balance. Overlap is the concept that not all moving parts of your body will start and end at exactly the same time. If you turn your head and point, your arm movement might begin before your head finishes turning. Overlap is nonexistent if the head and arm start & stop on the same frame or if the arm waits to move until the head has completed its motion. Such non-overlapped motions tend to look robotic.

6. Slow In/Slow Out: Organic motion tends to accelerate and decelerate into and out of action. (Except when met with a force that causes an abrupt stop or direction change.) This type of motion often does not apply to mechanical objects.

7. Arcs: The parts of an articulated skeleton move as a result of joint rotations. When a wrist travels from point A to point B, it does so as a result of elbow and shoulder (etc) rotation. Therefore, the motion will tend to arc. It is possible to move one's wrist in a straight line, however, continuous compensatory adjustments in the rest of the arm are required to achieve this motion and such movements tend to look less organic (or at least more deliberate - like a straight punch). If you want a character to move like a robot, ignore the concepts of arcs, overlap and slow in/slow out.

8. Secondary Action: Any motion that is 2ndary to the main action. For instance: drumming your fingers on your knee while talking. 2ndary actions often reveal emotional subtleties or hidden thoughts. If the 2ndary action pulls the viewer's attention away from the main action, however, it becomes the main action.

9. Timing: Varying speed of motion can indicate different types & strengths of forces. Timing can demonstrate different attitudes. Turning one's head very quickly implies a different motivation from doing so slowly. Fast walks can imply determination. Slow walks can imply depression. Metronomic timing is usually undesirable.

10. Exaggeration: Exaggeration is used to increase the readability of emotions and actions. Animation mediums don't deliver all of the same information as does real life. A video screen is not truly 3-D. Sound comes from a single source. Depth perception is not interactive. Because of the limited information being delivered, it's often necessary to exaggerate in order to effectively tell the story of a particular performance. Effective exaggeration isn’t always a matter of making a motion larger, though. Significantly decreasing an action is also a type of exaggeration. Accentuating the subtleties, that is. Completely stopping a character's motion for an unnaturally long period of time can demonstrate a particular emotion: Perhaps impatience or disgust. Exaggeration is, of course, especially apparent in cartoon-style animation.

11. Solid Drawing: In cel animation, each individual drawing should be a successful work of art on its own. This adds to the appeal & readability of a performance. It is also important to stay "on model". Each drawing should look like the character being presented. It is distracting when the size of a character's head is inconsistent during the course of an animation.

12. Appeal: Is the presentation of your idea pleasant to look at? (Or unpleasant if that is the intention). Are general aesthetics being effectively applied (composition, character design, color, camera angles, etc)?

And 12 more...

13. Simplicity & Readability: Don't unnecessarily over complicate your scene, character or performance. Do just enough to tell the story. Too much secondary and too many details can sometimes confuse the issue and make the idea being presented unclear.

14. Posing: A subset of "staging". Interesting poses are extremely important for effective & natural-looking animation. Pay attention to center of gravity issues (does your character look like he's going to fall down?). It’s usually a good idea to avoid too much symmetry in your poses. One hip is often a little higher than the other. Weight is rarely distributed evenly over both feet. How does the silhouette read?

15. Forces: An object moves when forces are applied to it. Consider where these forces are coming from. Are they being generated from within (desire, intention, muscle movement) or from without (gravity, the wind, a push from another character)? The origin, magnitude, direction & duration of these forces will dictate how your characters move. How is your character affected by these forces? Does your character resist them or does he “go with the flow”? Do multiple forces cancel out one another? Understand a force’s “attack & decay”. How powerful is the initial “hit” of the force? How long does an object continue reacting to the force? Consider the material of the object. Rubber “decays” slower than cloth.

16. Weight: Demonstrating the implied mass of a character. This is a function of the proper application of squash & stretch, anticipation, follow through, overlap, timing, exaggeration, and slow in/slow out. Whether or not a character looks especially heavy or especially light when getting up from a chair is dependent upon how these principles are applied. A heavier object requires more force to set it in motion. This is often demonstrated by increasing anticipation. Likewise, it requires more force to slow, stop or reverse the direction of a heavier object. Placement of your character’s center of gravity is an important aspect of weight. Physics rules indicate that a static object’s center of gravity must be directly above or below the average of its point(s) of suspension. For instance, when you stand on one foot, your COG needs to be directly above your support foot. Otherwise, you will begin to fall. Of course, this all changes if you are in motion. Pay attention to pivot/leverage points as well. Watch out for isolated body part movements. Even the simplest arm move often involves contributing motion from the shoulder & torso. Keeping your individual body parts appropriately working together is another way of indicating weight.

17. Twinning & Texture: To maintain natural-looking performances, it is usually desirable to break up the motion of individual body parts so they are not doing the exact same thing at the exact same time. ie: when slapping your character’s hands on a table, you might want the left hand to hit a frame or two before the right. A variation of the twinning concept is when members of a swarm or flock are exactly mimicking one other. Pay attention to the overall “texture” when animating groups of objects or characters. Consider a flock of birds or a field of grass reacting to the wind. What is the overall feel of the group? Is there enough variety in the trajectories of the individual elements? Is every bird flapping its wings at the exact same frequency? Is the wind affecting every blade of grass in exactly the same manner at exactly the same time? Are the individual elements supposed to be working together? If so, are you using an appropriate amount of variation between these individuals? Are your synchronized swimmers exactly synchronized? If so, is this intentional? Even when individual members of a group try to copy one another exactly, minor variations often occur.

18. Details: Sometimes the difference between a good animation and a great animation comes from effective attention to detail. You never know where a viewer's eyes may be wandering. Just because the main focus of a shot is on your character's face, don't forget to animate the toes. Details like thigh muscles jiggling when a foot hits the ground add to the naturalism of a performance & can help tell the story. Introducing naturalistic imperfections will also add to the believability of your shot. Keep in mind, however, that it is usually not desirable to confuse the action with too many details. (see principle #13) Watch out for technical glitches such as geometry intersections and IK “pops”. Material integrity is also an important detail to consider. Is it appropriate to squash & stretch a rigid object such as a stone? Some animators will do this as an aesthetic choice. Others prefer to follow realistic rules of physics. And don’t try to hide animation errors behind overly detailed modeling, lighting, texture maps & particle effects. This is an undesirable variation of the “attention to detail” concept. Consistent style, physics and quality are also important details to maintain.

19. Planning Ahead: It's always a good idea to plan out a performance before starting. Act out the motion with a stopwatch and take down some numbers. This is very important in stop motion where it's impossible to go back and fix an individual part of a performance after it has been filmed. It's especially important to plan ahead when you have a deadline. Most of us rarely have the opportunity to animate by trial and error. As the carpenters say: Measure twice, cut once.

20. Hookups & Continuity: To maintain flow and readability, each scene needs to “cut” properly with the next. Are the spacial relationships between your characters consistent from one scene to the next? Does an object’s trajectory look like it continues sensibly after a camera cut? Does the new camera position confuse the clarity of the action? If you cut away from a particular action then return later, do the changes in the scene make sense with the length of the time lapse? Do your actions overlap? Should they? Sometimes it is desirable to intentionally break the rules of continuity, but care should be taken when doing so.

21. Acting: Animation is acting. Always keep this in mind. What is your character's motivation & emotional state? Such information should be revealed in your performances. A shot’s story can't be told if the characters are simply moving through the scene without any indication of intention or personality. Always ask “why?” Every movement should have a purpose. Arbitrary motions rarely contribute anything to a character’s performance. Contrasts are an important element in acting as well. Animating the same character with significant contrasts in timing can imply completely different personalities & motivations.

22. Blocking/Refining: A third method of animating as opposed to Straight Ahead or Pose to Pose. This method (very often utilized in CG) involves initially establishing the overall posing, timing and trajectories of your character as a "blocking" phase. Details are added after these global issues are refined and approved. Similar to the (sometimes) preferred method of painting where the overall composition and colors are established rather abstractly and the image slowly comes together as a whole as the details are refined with smaller and smaller brushes. As opposed to finishing one corner of the painting before moving on to another. This blocking/refining method is especially desirable in CG so that global timing can be refined before there are a huge number of keyframes to tweak.

23. Understanding The Principles: It's not enough to simply be able to recite these principles from memory. To animate effectively, you must truly understand them. These principles need to be applied appropriately, and sometimes certain ones need to be left out entirely. For example, a cat does not always need to crouch down in anticipation before jumping up (except on big jumps or specifically predatory/playful actions) because its natural posture is already an anticipatory crouch. And while it is certainly okay to squash & stretch a bowling ball, bending the laws of physics thusly should be the result of an aesthetic choice rather than blind implementation of the squash & stretch principle. If you are asked to make your character look heavier, you can only accomplish this if you truly understand which principles need to be applied and how. Rules are made to be broken, but one must truly understand a rule before it can be broken creatively and appealingly.
24. Forget the Rules: After you've studied and understood the fundamental principles of animation, strive to use them instinctively rather than methodically. Try not to get too caught up in the idea of applying them academically at every turn. Often, it's better to turn off the analytical side of your brain and follow your gut instead. Your best weapon as an animator is your ability to self-critique objectively and effectively, especially in CG, where trial and error is such a viable technique. When you review your own work, don't ask yourself which of the fundamental principles are being applied properly, rather simply ask yourself whether or not your animation feels right. The ability to use the vocabulary of these principles is indeed important when you are teaching or supervising, however, never forget that your instincts as well as your innate and objective sense of style and appeal are much more powerful production tools than any available list of rules or principles.

My thoughts....

I’ve received a few emails asking me a couple of questions. I’ll answer some of them right here…

1) Hi Amrit! What are your plans for your new job at Dreamworks Animation? And how do you feel about it?

Yeah, I’m feeling really, really excited about my new job!! I’ll be starting as an entry-level animator for Dreamworks Animation and it’s a dream come true! I’m all set to blast! I know. I’ll have to work really hard and keep my learning curve very steep! Since I love my work, it would be really fun for me. :)

Future plans?.... Well, I like to keep myself in present, and I just let the future come to me…. and say “Hi!”. So, I haven’t planned a lot. All I know is work HARD and have FUN! Yeah, you could call it my “mantra”! All I know right now is, I’ll be working really, really hard for my company and try to create some really nice and fun animation for everyone one! :) ………. Wow! I’m making it an essay! Sorry guys… I’ve a bad habit of doing that. Alrighty, next question!

2) Hey there, You got selected! That’s a great news young man! Who would you like to thank?

Firstly, I’m really thankful to God. I don’t know if I deserve it, but these are all his gifts. My first job at Dreamworks!! It was just a dream. I really never expected that! :)

I’m thankful to my friends and family who care for me and encourage me not just to become a better animator, but a better human being all around. I’m thankful to my mentors/animation gurus, Keith Lango, and Jason Ryan. They’ve always been an inspiration for me, and I’ve always wanted to be like them!

Before I subscribed to Keith’s VTS (video tutorial service), I hardly knew what animation was all about. Keith’s VTS is just like gold mine for me and I’ve learned a lot, and still learning tonnes from it!

Jason Ryan has always been kind enough to help me out with my animations and stuff. When I watch him animate something, I’m like….. I wanna DO THAT TOO!! He makes everything so much fun and breaks down the animation process in such a way that everything becomes so easy. Jason has always encouraged me a lot. He is really an inspiration for every animator! He will be starting his new, super cool, online animation tutorials and I’m really very excited about that!! :)

And finally I’m thankful to the great guys at Dreamworks who noticed my talent and gave me this great opportunity to work with them!

Well, that’s it for now guys. See ya’ll soon!

Cheers! :)

My first "dream" job!

Hey everyone!

I got selected and got my first dream job as an animator for DreamWorks Animation. DreamWorks Animation has recently signed an agreement with Technicolor Content Services division of Thomson to set up an animation studio at Paprikaas Interactive, in Bangalore, India.
So Right now, I'm really, really excited about all this. I flew to Mumbai, met some really great people from DreamWorks Animation. It was a very nice experience. I must admit that I was a bit nervous (umm... I mean really nervous!), but the guys were very cool and helpful.... and I'm glad they liked my demo reel! Yay! I must thank Jason Ryan for all his help and support. Without his help, I couldn't have done it. I'll be working under some super cool supervising animators and learning loads from them! :D

Cheers everyone!
