Anticipation & Overshoot:


The most important thing to remember is that great animation doesn't happen from Point A to Point B, it happens at point A and Point B. Meaning that we must show the audience what is going to happen by anticipating the action (Point A) , do the action, then show the audience what just happened by overshooting the pose and settling back in (Point B). I'll use the principles of Squash and Stretch to demonstrate Anticipation and Overshoot.

You'll notice 4 balls. The ball on the far left has no anticipation or overshoot. It looks stale and lifeless and doesn't move in a convincing way. The ball in the Left middle has anticipation and overshoot. It anticipates the action by squashing (Pose A), does the action,... then shows the audience what just happened by overshooting it's next resting position (Pose B). We'll call this action the Short Bounce. It has character, moves in a convincing way, and keeps the audience's attention where we want it but it lacks exaggeration.

Exaggerated action is what makes good animation great. Study the Short Bounce for a while and practice the principles behind it in your own animation. It's VERY important to MASTER this action and principles behind it in your own character animation before moving on to The Long Bounce. You must know the basic rules before you can break them.

The next ball in the scene on the Right Middle is very similar to to the Short Bounce except that it breaks a few normal rules of physics by exaggerating the action. We'll call this the Long Bounce. It accelerates much more quickly than the Short Bounce, reaches it pinnacle quicker, shows the audience what it's doing, then finishes the action. Using this principle correctly and in the right spots can add that extra ummph and weight to your action. This is a technique for more advanced animators. Beginners should concentrate on learning how and when to use anticipation and overshoot before attempting to break the rules like this.

The fourth ball on the right hand side is a variation on the long bounce and adds an extra bit of action between Point A and Point B. Its action can be described as Point A to C to B. Instead of traveling in a straight line it follows a slight arc and is even more exaggerated. I call this 'putting the juice in'. For those animators that are more advanced, see how far you can push those extreme poses, then add a little flavor to it by doing something unexpected in between (Point C).
