Adjusting All Opacity Keyframes of a Clip
You can raise or lower the values for all opacity keyframes in a clip (or multiple clips) at
one time by choosing Modify > Levels (or pressing Command-Option-L). You can adjust
all opacity keyframes, either up or down, maintaining the relative positions of the
keyframes, or you can set all keyframes to a single, absolute level (effectively removing
any variations in opacity over time). You can also use this command to modify audio level
keyframes. For more information, see
“Adjusting Audio Levels in the Timeline.”
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 multilayer effects. You’ll layer two clips and adjust a clip’s
opacity over time. The topmost clip fades in, appears superimposed above the other clip
for a few seconds, and then fades up (nearly obscuring the underlying image) before
fading away completely.
