If you're talking about an Autorun event (like a cutscene or something), then you could also turn on a switch at the end of the event. And then do the same thing FireRaven suggested: 1.) Create a new page within the event, 2.) On the left of that page where it has conditions, check the switch that you just turned on (ie - if "switch 3" is ON, then do this), 3.) Leave the page blank and make sure it's not an autorun event (I usually leave it on "action" or something).
If there are characters involved in your cutscene that you want to disappear, you can also create new pages within their events, checking the switch that turned on at the end of the autorun event, and then leaving that new page completely blank.
