TIMELINE The Main Timeline window shows the temporal relation of cues and effects, as

well as the layering of overlapping media. Cues control the display and

presentation of media, and use tween tracks to control various aspects of the

media.

The amount of time displayed in the timeline window can be controlled using

the button in the lower left corner. Zoom in to increase the precision by which

you can position cues and set their duration, or zoom out to get a better over-

view. The center part of the button allows you to change the scale gradually.

Changing the time scale has no effect on the behavior of the timeline or its

cues. See “Main Timeline Window” on page 101 for more details

Tween tracks are used to animate properties of media cues, such as position

and opacity, over time. The tween tracks of the currently selected cue appear

at the bottom of the timeline window, called the tween pane. See “Tween

Tracks” on page 179 for more details.

◆ HINT: When tween tracks are visible, you can toggle between the cue and

tween panes using the Tab key.

Adding Media Cues To add a media cue to the timeline, drag the media onto the timeline and drop

it at the desired layer and time position, as shown on page 61. Cues can be

dragged along the timeline to change their timing relationship. Select multiple

cues by Shift-clicking the cues, or by clicking and dragging diagonally, starting

from a point where there are no cues.

◆ IMPORTANT: Do not overlap cues on the same layer. Doing so may cause

images to display incorrectly. When you want images to overlap in time,

always put their cues on separate layers. Overlapping cues are indicated

by a red warning line above the cues.
