Convert PowerPoint 2013 to Video
Among all the new features of PowerPoint 2013, being able to save PowerPoint as MPEG-4 video seems outstanding. Because most portable devices like iPad, iPhone or Android devices support MP4 video instead of WMV video, which means you can view PowerPoint 2013 presentations on these devices now.
Open your PowerPoint presentation using PowerPoint 2013 program. You can then choose File, Save As, MP4 OR click File tab, and then Export, and finally click Create a Video.
Now choose the size of the video, whether to use record timings and narrations for the presentation, and then click Create Video.
Then you can choose MP4 or WMV as output format.
