Click the disclosure triangle to display four crop parameters. Each defines the number of
pixels to be cropped from each of the object’s four sides, relative to the outer edge of the
bounding box that surrounds it. These parameters are similar to the crop parameters that
appear when an object is selected in the Media tab, except that cropping an object in
the Layers tab only crops the currently selected instance of that object in your project.
Duplicates of that object remain untouched. If you want to crop all instances of the
object simultaneously, use the Crop parameter on the object in the Media tab. For more
information, see “
Object Parameters in the Media Tab
Timing: These parameters control all aspects of clip retiming. For more information,

Making Clone Layers
In a motion graphics project, sometimes it is necessary to reuse a complex object in
other parts of the project multiple times. Although you can duplicate or cut and paste
any object, if you update the original, none of the changes you make are applied to the
copies. It can become a tedious and difficult management task. If you find yourself
applying the same filters and masks to more than one copy of an object, you should
take advantage of the Make Clone Layer command. Making clone layers has the
additional benefit of improving project playback and rendering performance.
To create a clone layer, do one of the following:
m
Select the object from which you wish to make a clone layer, then choose Object >
Make Clone Layer.
m
Control-click an object in the Canvas, then choose Make Clone Layer from the shortcut
menu.
m
Control-click an object in the Layers tab or Timeline layers list, then choose Make Clone
Layer from the shortcut menu.
A clone layer is created and appears in the center of the Canvas. In the Layers list, the
clone layer appears with the default name “Clone Layer.” A Clone Layer icon appears
next to the name.
Note: If your source object is located in the center of the Canvas, the two objects
overlap.
