228 LESSON 12
Acquiring and Editing Audio
6 Let’s create fade-in and fade-out effects on this audio track. Drag the current-
time indicator to about two seconds from the start of the clip. Ctrl-click
(Windows) or Command-click (Mac OS) the volume level graph to create a
keyframe at that location.
7 Now let’s create a key frame at the beginning of the clip. Ctrl-click (Windows)
or Command-click (Mac OS) the volume level graph to create a keyframe there,
and then drag that keyframe to the bottom of the audio track, essentially muting
the audio at that location.
8 Play the beginning of the clip to hear the fade-in. Just for fun, drag the keyframe
at the two-second spot closer to and further from the start of the clip. That’s
how you can easily change the duration of your fade-in.
9 Create two more keyframes on the Audio 5 track at 30:10 and at the end of the
clip; then drag the keyframe at the end of the clip down to the bottom of the
audio track.
10 Play the end of the clip to hear the fade-out. Drag the keyframe at 30:10 closer
to and further from the end of the clip. That’s how you can easily change the
duration of your fade-out.
11 Right-click (Windows) or Control-click (Mac OS) the second and third
keyframes, and choose Ease In and Ease Out, respectively.
#
Note: As you slide keyframes around in the clip, you will invariably change their volume settings.
Adjusting keyframes on the Timeline is quick and easy. You’ll want to use the Volume effect in the
Effect Controls panel to fine-tune those keyframe parameters.
#
Note: As you can
see, you can apply
keyframe interpolation
in the Timeline.
However, selecting
one of the Bezier curve
options would create
a more pronounced
curve in the middle. So,
stick with Ease In and
Ease Out for most audio
keyframes.
