Dynamic Content transitions are new transitions effects introduced in PowerPoint 2011 on the Mac side — they already existed within PowerPoint 2010 for Windows. When a Dynamic Content transition is applied to your slide, it will work on the entire slide content at a time, but not on the slide background. This makes the transition occur on your content that moves independently on and off the screen. PowerPoint 2011 provides seven effects for Dynamic Content transitions — experiment with these effects for direction and timing to create some great looking presentations.
