Tutorial 1 The Motion Interface 31
The left side of the Timeline is called the Timeline Layer list, and is similar to the Layers
list in the Project pane. Like the Layers tab in the Project pane, you can select, reorder,
lock, group and ungroup, rename, and add or remove objects and layers in the
Timeline Layer list. Actions made in either list are reflected in the other.
In the right side of the Timeline, each object is represented by a colored bar that sits on
a gray, horizontal track. The object type is identified by the color of its bar. Layers
appear as blue bars in the Timeline.
The ruler that appears above the bars represents frames. In the above illustration, the
playhead is sitting at frame 96. This is also represented in the Current Frame field in the
Timeline Layer list (and to the left of the transport controls).
