_ Tip: The Timeline panel measures time in seconds and frames, depending on the frames-persecond (fps) rate. So 1:15 equals 1 second and 15 frames. At 29.97 fps, 1:15 is frame 45.

As the character moves, his body squashes and stretches. Squash and stretch is a traditional animation technique that adds realism and weight to objects. It’s an exaggeration of the effect that occurs in real life when a moving object comes into contact with a stationary object, such as the ground. When squashing and stretchingare applied correctly, the volume of the character doesn’t change.

The easiest way to understand the principle of squash and stretch is to view an animation of a bouncing ball. As the ball lands, it partially flattens, or squashes. As it bounces up, it stretches.

To see squash and stretch in action, open the Squash_and_stretch.aep project file in the Lesson08/End_Project_Files folder.

The character steps on a banana peel, loses his balance, and falls. The falling movements occur more quickly than the walking cycle. To surprise the viewer, you’ll animate the character to fall off the screen.
