audio keyframes (discussed in Chapter 13). To change this value over time, you need to have at least two key-
frames at different positions in the Timeline: one keyframe that sets the starting value and another keyframe that
sets the ending value.
Keyframes can be added in the Inspector, the Timeline, or via the on-screen controls in the Viewer. To create an
animation, select a clip in the Timeline and place the playhead where you want the animation to begin. Add
your first keyframe, move the playhead to another position on the clip, and adjust a value in the Inspector or
make a change via the Viewer's on-screen controls. Final Cut Pro automatically adds another keyframe whenev-
er you change the playhead position and adjust an effect's parameter. When you've finished your animation
click Done.
The on-screen controls for the built-in effects include a Keyframe button, represented by a diamond icon with a
plus sign. Clicking the Keyframe button adds a keyframe and turns the icon orange with an X (see Figure 14.5).
To delete a keyframe, position the playhead on the keyframe and click the orange X icon. The left and right ar-
rows on either side of this icon jump the playhead to the previous or next keyframe position. The Viewer in Fig-
ure 14.5 shows a picture-in-picture effect that uses the Transform's Scale and Position parameters to shrink and
reposition a Connected clip in the corner of the frame. When played back, the Connected clip begins as a full
frame (the first keyframe) and then scales down and moves into the corner (the second keyframe).

Transform effects display a red, dotted line to show the path that the animation takes over time. You can choose
between a Linear and Smooth path by Control-clicking on a keyframe (see Figure 14.6).
