Animating Crop with Keyframes 147

The animation for this layer will now start a little later than the layer below it.

13 In the brayer_03b copy layer, move the first keyframe to the right a little bit more than

the first keyframe in the brayer_03b layer.

14 Move the first keyframe for each of the layers in the Graphics Under group to a

different point in time. When you reach the upper vellum layer, Shift-drag to snap it

to the lower vellum layer. As you Shift-drag, thin vertical lines appear on the layer bar,

representing all possible snapping points.

15 Repeat the process for the layers in the Graphics Over group, staggering the keyframes.

Then play the project and adjust the keyframe locations to your liking. The layers

now drop into the scene at different times, but they all end in their final positions

at 5:00.

For a final touch, you can animate the strips of vellum to spread out just before

they land.

Animating Crop with Keyframes

To make the strip of vellum appear to open up, let’s animate its Crop parameter. Because

the graphic comprises two layers, we will animate them in tandem.

1 Stop playback, drag down on the top bar of the Timing pane to return it to its origi-

nal size, and move the playhead to the start of the project.

2 In the Layers list, Shift-select the torn_vellum_strip and torn_vellum_strip copy lay-

ers, and press Shift-K twice to move the playhead to the second keyframe at 5:00. In

the Properties Inspector, a solid diamond appears in the Position Z Animation menu,

confirming that the playhead is parked on a keyframe.
