Chapter 4 Using the Timeline 293
Editing Objects in the Timeline
During the process of designing and implementing a motion graphics project, you
place objects in the Timeline and Canvas, move them forward or backward in time, and
trim them to match the timing of other objects in your project.
Motion has several features that help you modify the objects in the Timeline. You can
arrange your objects to begin and end at designated frames, and to begin and end at
the best frames within the clip. You can also use powerful alignment and timing tools,
such as snapping and markers. When displayed, you can also modify keyframes in the
Timeline. This section describes the various ways you can perform these actions in the
Timeline.
Motion uses the terms move, trim, and slip to describe the different ways of editing
Timeline objects.
Move: Changes the location of an object without affecting its content or duration.
Trim: Changes the duration of an object without affecting its location or content.
Slip: Changes the content of an object without affecting its location or duration.
Moving Objects
Move an object when you want it to begin and end at a different point in the project.
To move an object:
m In the Timeline, click an object bar and drag left or right to move it in time.
A tooltip appears that identifies the new In and Out points of the clip as you drag, so
you can drag it to the frame you want. The Delta symbol (∆) indicates the number of
frames you are moving.
To move an object and snap to neighboring items:
m Press Shift as you drag the item in the Timeline.
Snap-to lines appear and the edges of the clip automatically line up precisely with
these lines.
