You can animate shapes using both behaviors and keyframes. In addition to using Basic
Motion, Simulation, and Parameter behaviors, shapes have their own special category of
Shape behaviors. Shape behaviors allow you to oscillate, randomize, or wriggle the
individual control points of shapes, to “write on” a shape outline over time, or to apply
tracking data to the control points of a shape.
You can also modify a paint stroke created with the Paint Stroke tool (in the toolbar)
based on how it was drawn with the stylus. For example, you can apply the Apply Pen
Pressure behavior to a paint stroke in your project and map the pressure used in drawing
the stroke to opacity. The resulting stroke appears more opaque in the segments where
you pressed hardest when drawing that stroke.
Basic Motion and Simulation behaviors animate multiple parameters of a shape, such as
Position, Rotation, and Scale. Applying behaviors to shapes works the same as with any
layer in Motion, and keyframed animation of any of these parameters is stored in the
For more information on using Basic Motion, Parameter, and Simulation behaviors, see
