Identifying Proxy Items In The Project Panel; About Nesting - Adobe AFTER EFFECTS 7.0 Manual

Identifying proxy items in the Project panel

In the Project panel, After Effects marks the footage name to indicate whether the actual footage item or its proxy is
currently in use:
•
A box containing a black square indicates that a proxy item is currently in use throughout the project; the name
of the proxy appears in boldface in the project list.
•
An empty box indicates that the actual footage item is in use throughout the project.
•
No box indicates that no proxy is assigned to the footage item.

Nesting

About nesting

Nesting is useful when you want to apply a single transform property to a layer in more than one way. It adds another
opportunity to apply masks, effects, or transform changes.
For example, you could use nesting to make a planet both rotate and revolve (moving like the Earth, which spins on
its own axis and also travels around the sun). By nesting, you can apply rotation to the planet in one composition and
then move that composition into another composition containing the background. The planet composition becomes
a new layer in the composition containing the background. You can then apply rotation to this new layer to make it
revolve.
Another way to configure this example would be to use parenting. See "To work with parent and child layers" on
page 208.
When you change certain settings in the current composition, these propagate through to the nested compositions.
These settings include the Quality options under Layer > Quality, several options under Layer > Switches, and three
options on the Timeline panel menu: Enable Motion Blur, Enable Frame Blending, and Draft 3D. The Resolution
setting for the original composition also applies to nested compositions.
If you do not want these switch settings for the current composition to apply to the individual nested compositions,
you can change that at the preferences level.
