One of the great things about PowerPoint is that you can embed video files into your presentations. The downside of this is that the embedded video files can dramatically increase the size of the presentation. Fortunately, you can compress the videos to keep the size of your presentation down.

The compress media files embedded within PowerPoint 2010:

1. From the File tab, click Info.
2. Click Compress Media within the right hand pane.
3. From the list of options, click Presentation Quality. This option saves space while maintaining the overall audio and video quality.
4. Once the compression process is complete, click Close.
