You can create a layer from any footage item in the Project panel, including another composition. After you add a footage item to a composition, you can modify and animate the resulting layer.
When you add a composition to another composition, you create a layer that uses the composition that you added as its source. (See Nesting, precomposing, and pre-rendering.)
The Still Footage preference setting (Preferences > Import) controls the default duration of layers that use still footage items as their sources. By default, when you create a layer with a still image as its source, the layer’s duration is the duration of the composition. You can change the duration of the layer after it’s created by trimming the layer.
Often, the next step after adding a layer to a composition is scaling and positioning the layer to fit in the frame. (See Scale a layer.)
Create layers from one or more footage itemsWhen you create layers from multiple footage items, the layers appear in the layer stacking order in the Timeline panel in the order in which they were selected in the Project panel.
Drag the selected footage items to the Composition panel, or press Ctrl+/ (Windows) or Command+/ (Mac OS).
Drag the selected footage items to the Timeline panel. When you drag the item into the layer outline, a highlight bar indicates where the layer will appear when you release the mouse button. If you drag the item over the time graph area, a time marker indicates where the layer’s In point will be when you release the mouse button.
Drag the selected footage items to the composition name or icon in the Project panel.
Create a layer from a trimmed footage itemYou can trim a moving-image footage item in the Footage panel before inserting a layer based on that footage item into a composition.
Replace layer sources with references to another footage item
