Chapter 12 Keyframing 457
For example, in the real world, when objects move, they obey rules of physics such as inertia and
momentum. Using Motion’s Keyframe Editor, you can simulate these effects in motion graphics.
The curves of animated parameters also provide a way of seeing how an effect changes over
time. Curves are laid out in a graph where you can compare them, one over another.
The Keyframe Editor makes it easy to add and delete keyframes, as well as move them in two-
dimensional space to modify their values (up-down) and their positions in time (left-right).
You can manipulate curves with the tools Motion provides, and you can define a variety of
interpolation methods, creating dramatically different types of effects. You can also apply
Parameter behaviors to curves via the Keyframe Editor by Control-clicking the curve name and
choosing a Parameter behavior from the shortcut menu. For more information about Parameter
behaviors, see
Add a Parameter behavior on page 299 and Parameter behaviors overview on
page 332.
Note: The parameters visible in the Keyframe Editor represent the object or objects selected in
the Layers list, Canvas, or Timeline. If you select one item in the Layers list, Canvas, or Timeline,
only parameters for that object are shown in the Keyframe Editor. If you select a group in the
Layers list, Canvas, or Timeline, all parameters for all objects in that group are shown in the
keyframe editor.
