PowerPoint 2010 has better video capabilities, accepts more video file formats, and can do a lot more with videos, including trimming of video clips. However, it also embeds all inserted video clips by default — and this can result in huge presentations that contain huge video files! This ultimately occupies oodles of disk space and may also make PowerPoint work a wee bit slower. To tackle this problem, you can explore the new media compression abilities built right inside PowerPoint 2010 — you no longer need any third-party media compression tool since PowerPoint’s native Media Compression options make this task very easy indeed.
