Timelines can contain multiple video and audio tracks. An edit sequence on a track is made of segments and transitions. Video and audio segments appear as a series of rectangles on their associated tracks. Transitions appear as cuts or icons between segments.
Video tracks can be made up of multiple layers. Layers are used to stack video vertically to create composite effects and transitions. If you have more than one layer or track, the positioner's focus point indicates which one is current.

PositionerIs the “playhead” for playing the clip. The frame directly beneath the positioner is displayed in the viewport or is the current location for an edit such as a dissolve or cut.
Focus pointIndicates the current track. In vertical editing, the positioner's focus point indicates the top layer (focus layer) in the vertical edit.
Patch and track identifiersIndicate patching for video and audio tracks. See Patching Video and Audio Channels.
Selector iconClick to select a layer or track.
TrackContains the segments and transitions that you edit together.
LayerUsed for vertical editing and timeline compositing. See Vertical Editing.
ElementRefers to the video segments, audio segments, and transitions that make up an edit sequence. Elements are colour coded to make them easier to identify, as illustrated in the following table. Coloured bars on top of the elements indicate their process and lock status. See Identifying the Status of Timeline Effects.
