You have a 5 minute video or audio clip playing on your slide. And exactly after the clip has played for 30 seconds, you want some text to appear super-imposed above the video clip. It might seem difficult, but you can end up with these results quite easily using the Trigger Animation option. These Trigger animations typically happen as a result of a click on some other slide object — but in PowerPoint 2013, you can now cause Trigger animations to also happen on media playback through a Bookmark.
