Step 3: Insert the overlay
When you are ready, you can create an action in the MediaLive channel schedule to activate (insert) the overlay. You can create the action at any time – before the channel has started or while it is already running.
The schedule is a timetable that is attached to each channel. The schedule is designed to let you specify actions to perform on the channel at a specific time. You can set up the action so that a motion graphic is active for a specific time, or so that it is active indefinitely. In both cases, you can stop the overlay at any time by creating a deactivate action.
