362 Chapter 4 Using the Timeline
The number of frames in the region is added to the project, beginning at the end of
the selected region and pushing any existing objects further out in time.
Project Duration
Motion projects default to ten seconds in length. You can change this duration to
match the needs of your project. To learn how to change the default project duration,
see “
General Tab of the Project Properties Dialog ” on page 184.
To change the project duration, do one of the following:
m Drag in the project duration field in the lower-right corner of the Canvas. Dragging to
the right extends the length and dragging to the left shortens it.
m Click the project duration field and type a number into the value field.
m Choose Edit > Project Properties (Command-J) and change the value of the project
duration field in the dialog.
Note: You can click the stopwatch button to switch between viewing the project
duration field in frames or timecode.
Adding Markers
A marker is a visual reference point in the Timeline that identifies a specific frame. You
can add as many markers as you want in the Timeline ruler while playing the project, or
when the playhead is stopped.
Use markers to:
 Add a visual reference to a track
 Add a visual reference to a project marker in the mini-Timeline
 Align other tracks, objects, or keyframes to an important point in time
 Add notes about a particular area in your project
