Timeline Layers list
The left side of the Timeline is the Timeline layers list. Like the Layers list in the Project pane,
objects appear in the project hierarchy categorized into layers and groups. The Timeline layers
list contains many of the same controls as the Layers list in the Project pane:
Show/Hide Masks button
Show/Hide Behaviors button
Show/Hide Filters button
•
Activation checkbox: Turns the visibility of an object on and off. When the object visibility is off,
you can still modify the object’s parameters and manipulate its onscreen controls.
•
Name field: Identifies the object by name. (This column is identical to the Name field in the
Layers list.) To edit the name, double-click the text area of an object, enter a name, then press
Return. In projects that contain a camera, the Isolate button also appears in this column.
•
Isolate button: Appears for a layer, group, or camera in a project that contains a camera. The
button has an active and inactive state. Clicking the Isolate button for a layer or group sets
that object to its original face-forward orientation (so you can apply a mask, for example).
Clicking the button again returns to the previous view. Clicking the Isolate button for a camera
takes you to that camera’s view.
Note: When a group or layer is isolated, the name of the item replaces the current camera
listing in the Camera menu (in the upper-left corner of the Canvas).
•
Mask icon: Appears when a mask is applied to the layer or group. To turn off the mask, click the
icon. A red slash appears through a disabled mask’s icon.
•
Behavior icon: Appears when a behavior is applied to the layer or group. To turn off the
behavior, click the icon. A red slash appears through a disabled behavior’s icon.
•
Filter icon: Appears when a filter is applied to the layer or group. To turn off the filter, click the
icon. A red slash appears through a disabled filter’s icon.
•
Link icon: Appears when the layer has a corresponding audio element, such as a multichannel
QuickTime file. To unlink the video and audio (to edit them separately), click the link icon.
When they are unlinked, a red slash appears through the icon.
•
2D/3D icon: Switches a group between 2D or 3D mode. The same icon appears at the left of
the group name and indicates the 2D/3D status of the group. Layers cannot be 2D or 3D—
they are always 2D elements in a 2D or 3D group.
