Adding layers to compositions

When you add an item to a composition, you create a new layer for that composition. You can duplicate layers within a composition or even copy and paste layers from one composition to another. Use as many layers as necessary to create your composition.

A composition layer can be any of the following:

• Any footage item in the Project window list (including audio)
• Another composition in the project
• A text layer
• A solid, camera, or light you create
• An After Effects adjustment layer, which modifies all layers below it
• A duplicate of another existing layer
• A split layer
• A null object (See Using null objects.)
