Convert PowerPoint Presentations to Video at authorStream

Want to share a presentation with friends, co-workers, or the web at large without worrying about who does or doesn’t have PowerPoint installed? authorStream, a free presentation sharing site, offers the same kind of embed-anywhere utility as previously-posted SlideShare, but also provides options to download presentations as MP4 video files, putting slideshows with or without audio one step away from YouTube, iPods, DVDs, or whatever format comes in handy. To work as video, presentations must have either recorded narration or rehearsed timings added in PowerPoint, which the Digital Inspiration blog explains in detail at the via link below.
