Edit Videos In PowerPoint 2010
Continuing the theme of building in features that used to require other applications, PowerPoint 2010 has dramatically extended the amount of video and image editing you can do right in the program.
PowerPoint 2010 supports AVI, WMV, WMA, MP3, MOV, and H.264 formats, and you can set where the video starts and ends, insert bookmarks, and add fades and formatting effects. You can even trigger PowerPoint animations from specific places in the video.
These aren't terribly sophisticated features for a real video-editing program, and there are many free video apps available. And you'll still want to complete major video editing work before importing your clips into PowerPoint.
But having at least some video-editing capability actually in PowerPoint 2010 itself can save time-consuming steps if it turns out that you need to make changes in the way the clip works with your presentation.
