In each composition’s flowchart, individual boxes (or tiles) represent each composition, footage item, and layer. Directional arrows represent the relationships between components.
Nested compositions and other elements that make up the composition appear when you expand a composition tile.
Mid-gray lines between tiles in the flowchart indicate that the Video or Audio switch for those items is deselected in the Timeline panel. Black or light gray lines indicate that the switch is selected, depending on the User Interface Brightness preference setting.
