PowerPoint 2013 now supports multimedia better that make video and audio easier to include in your presentation. What does that mean for you?
• Out-of-box playback support for the ubiquitous H.264 video and AAC audio codec standards
• Older versions of PowerPoint previously required third-party installs to play these back.
• Better, smoother playback performance of your high definition videos in slide show
• Higher quality output when we optimize or compress your videos
