Using the Timeline

277

Enabling Timeline Tracks

To the left of each track in the Timeline Layer list is an activation checkbox that turns
that track on and off. When a track is turned off (disabled), it is ignored in the Canvas.
Not only can you turn video or audio objects on and off, but you can also disable or
enable effects such as masks, filters, and behaviors.

To turn visibility for an object on or off:

m

Click the checkbox at the left edge of the track you want to control.

When the box is checked, visibility is on, and when the box is unchecked, visibility is
off. Additionally, when a track is disabled, the entire track is dimmed in the Timeline.

Managing the Layer List

Motion allows you to collapse and expand different parts of your Layer list to show
more or less data to accommodate different working styles. Individual objects with
masks, generators, or filters can be collapsed to hide those effects bars. Furthermore,
whole layers can be collapsed to hide all of the objects contained within them.

When an object or effect is collapsed in this manner, it still appears in the Canvas
window. Unlike enabling or disabling tracks, collapsing and expanding the Timeline
Layer list is only an organizational tool to help manage the view of the Timeline.

To collapse or expand an object in the Timeline:

m

Click the disclosure triangle to the left of the object name. If no disclosure triangle is
present, that object cannot be collapsed or expanded any further.

Activation checkbox

is turned off.
