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 Window .
To change the project duration
Do one of the following:
µ
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.
µ
Click the project duration field and type a number into the value field.
µ
Choose Edit > Project Properties (or press 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
You can assign different colors to different types or markers and create marker groups.
For example, use green to label all audio markers or pink to identify all temporary object
markers.
