Using Markers with Audio
When you add project markers to the Timeline, they appear in the Timeline and Keyframe
Editor. You can use project markers to designate “hit points” as you play the project, to
jump to a specific point, or to highlight points to synchronize visual and audio events.
For information on adding and deleting markers, moving markers, editing marker
information, and using markers, see Adding Markers.
Audio Behaviors
Audio behaviors can be applied to audio tracks from movie clips with sound or to
standalone audio tracks. There are two ways to apply an audio behavior:
• Dragging an Audio behavior from the Library to an audio track in the Audio list or Audio
Timeline
• Selecting a track in the Audio list or Audio Timeline and then choosing an Audio
behavior from the Add Behavior pop-up menu in the toolbar
For more information about applying behaviors, see Applying and Removing Behaviors.
There are two useful behaviors to control audio tracks in Motion: Audio Auto Pan and
Audio Fade In/Fade Out.
Audio Auto Pan
Automates commonly used panning effects in an audio track.
Parameters in the Inspector
Pan Position: A slider that sets the position of the pan. If the Pan Position slider is set to
0, the sound is equally balanced between the left and right channels. With larger negative
values of Pan Position, the sound increases in volume in the left channel and decreases
in the right channel. With larger positive values of Pan Position, the sound increases in
volume in the right channel and decreases in the left channel.
Depth: A slider that sets how far the automatic pan occurs in the left and right channels.
Values range from 0 to 100.
Direction: A pop-up menu that sets the direction in which the pan moves over the
behavior’s duration. Choose Left or Right. If the direction is set to Right, over the behavior’s
duration the volume of the audio decreases in the left channel as it increases in the right
channel, giving the impression of a sound moving from left to right. If the direction is set
to Left, over the behavior’s duration the volume of the audio decreases in the right channel
as it increases in the left channel, giving the impression of a sound moving from right to
left.
