menu in the Effect Controls window.
To edit an audio transition:
Double-click the transition in the Timeline window and adjust the transition in the Effect
Controls window. See “Changing transition settings” on page 166.
To customize the rate of audio fade or cross-fade:
For each clip involved in the fade, adjust the clip’s audio volume keyframe graph instead of
applying a transition. See “Adjusting gain or volume levels” on page 175.
To set the default duration for an audio transition:
1
Choose Edit > Preferences > General.
2
Specify a value for Audio Transition Default Duration, and click OK.
Creating split edits
When audio clips are linked to video clips that don’t overlap, cross-fading the audio clips is
more complex than an audio-only cross-fade. The audio clips linked to video clips cannot
be dragged to overlap if the audio clips are on the same track, but you can move the audio
clips onto different tracks. The clip’s video and audio components need to be unlinked so
that you can move or trim them independently.
Cross-fading audio linked to video is useful when performing a split edit, in which a clip’s
video and audio components start or end at different times. In one version of a split edit,
called an
L-cut
, the audio Out point is later than the video Out point, so that you can
continue playing a video clip’s audio after the next video clip’s In point. Another kind of
split edit is an
audio lead
, called a
J-cut
, which you use when you want an audio/video
clip’s
audio to start playing before the video In point.

Cross-fading existing clips in the Timeline window usually requires extending the duration
of one or more audio clips. Whenever you extend the duration of a clip, additional frames
must be available in the clip’s source (master) clip beyond the current In or Out point. For
example, if you did not trim the beginning or ending of a source clip before adding it to
the Timeline window, the clip is already using all frames available from its source, so its
duration cannot be extended.
To create a split edit:
1
If necessary, click the triangle to the left of each track name to expand the audio tracks
you want to adjust.
2
Select one of the clips involved in the split edit, and choose Clip > Unlink Audio and
Video. Repeat for the other clip.
3
Select the rolling edit tool from the toolbox.
4
Starting at the audio edit point between the two clips, drag left or right.
Note: If nothing happens, make sure that before you start dragging, you position the
pointer over the visible audio edit point, not over an applied audio transition.
Panning and balancing
By default, all audio tracks output to the sequence’s master audio track. Because tracks
may contain different numbers of channels than the master (depending on whether they
are mono, stereo, or 5.1 surround tracks), it’s necessary to control what happens when a
track outputs to another track that has a different number of channels.
Panning
positions a mono audio track within a multichannel track. For example, if a car
drives by on the right side of a video frame, you can pan the mono track of the car’s audio
so that you hear it on the right side of the multichannel audio field.
Balancing
redistributes
multichannel audio track channels among the channels of another multichannel track.
