Example: Using Keyframes to Make Opacity Changes
This example illustrates how you can use Final Cut Pro to dynamically adjust opacity
over time to create sophisticated multilayered effects. You’ll layer two clips and adjust a
clip’s opacity over time. The topmost clip fades in, superimposes the other clip for a few
seconds, and then fades up (nearly obscuring the underlying image) before fading
away completely.
1 Edit two clips of equal duration into your sequence, each on its own video track.
Note: The clip you want to appear in front should be placed on track V2; the other clip
should be placed on track V1.
2 Open the clip on track V2 into the Viewer, then click the Motion tab.
3 Click the disclosure triangle for the Opacity parameter to reveal its overlay in the
keyframe graph area.
