136 Animating with Keyframes

You’ve now explored the basics of creating keyframes by recording them or setting

them manually for a single parameter on a single layer. Next, you’ll explore techniques

for applying and adjusting the keyframes of multiple parameters on multiple layers.

NOTE

For more information on keyframe interpolation, refer to the Motion 5 Help

document available from the Help menu.

Using Keyframes on Multiple Parameters and Layers

Because keyframes are so precise and flexible, they are often used to animate multiple

layers to move, spin, or blur at a specific point in time. In this exercise, we’ll return to the

Rockumentary project and animate all the title elements to fall into place and form the

final composition. Motion lets you quickly set keyframes for parameters on multiple

layers, and it also lets you choose which keyframes appear for editing in the Keyframe

Editor.

Keyframing Multiple Layers

The first step is to add keyframes that will lock in place all the layers that are to be

animated.

In previous lessons, you created the second half of this project, the composite image

of the title elements with the sequence of photos. You also animated the initial photos

and dates “falling” through space. Now we’ll concentrate on the middle part of the

project: animating the title elements into position. Unlike the photos and dates that
