The Events track, found at the top of the timeline in Advanced mode, is where you connect timeline animation to events with event markers and event labels. Event markers let you trigger events at specific points in the timeline, and event labels let you set up events that control the animation.
Because video ads do not support events, video ad timelines do not include the Events track.
Event markers 
Timeline-based events are set using event markers on the Events track. When the animation playhead reaches the event marker in the timeline, the event is triggered.

- Right-click the Events track where you want to add the event marker and select Add event from the pop-up menu.
