Adjust audio effects using keyframes
With Final Cut Pro, you can use keyframes to create simple changes to audio over time, such as
fading the volume or an effect in or out in the middle of a clip.
You place keyframes at specific points in a clip to change the parameter value of an audio
enhancement or effect at those points. For example, you can keyframe specific points for volume
or for an effect such as reverb or distortion.
You can set keyframes to adjust a clip’s volume directly in the Timeline or in the Audio
inspector. To see keyframes in the Timeline for all other effects, you need to display the Audio
Animation Editor.
For information about keyframes for video clips, see Adjust video effects using keyframes on
page 247.
