In the Timeline panel, you can split a layer
at any time, creating two independent layers. This is a time-saving
alternative to duplicating and trimming the layer—something you
might do when you want to change the stacking-order position of
the layer in the middle of the composition.
Note: To make new split
layers appear above the original layer in the Timeline panel, select
Create Split Layers Above Original Layer (Edit > Preferences >
General (Windows) or After Effects > Preferences >
General (Mac OS)). Deselect this option to make the layers
appear below the original layer.
Select one or more layers.
Move the current-time indicator to the time at which
to split the layers.
Choose Edit > Split Layer.
When you split a layer, both resulting layers contain
all of the keyframes that were in the original layer in their original
positions. Any applied track mattes retain their order, on top of
the layer.
After you split a layer, the duration of the original
layer ends at the point of the split, and the new layer starts at
that point in time.
If no layer is selected when you choose
Edit > Split Layer, all layers are split at the current
time.
Lloyd Alvarez provides a script that automatically detects edits in a footage layer and splits it into a separate layer for each edit (or places a layer marker at each edit): http://aescripts.com/2008/01/18/magnum-the-edit-detector/
