You
            can work in a container and see the results in context of the record
            timeline.
         
         To edit a container in context of the
            record timeline:
         
         
            - From the record timeline, lock the Player
               focus to Record focus. First, select Record from the Focus box and
               then click the LED on the Record Focus button.
            
- Make sure Preview FX is selected in the
               Player.
            
- Double-click a container to enter it. 
            
- Add or edit soft effects or transitions.
               The container's result
                  is displayed in the Player in context of stacked layers in the record
                  timeline.
