How can I convert a PowerPoint presentation to a video file?
Hello Dr. Sunil,
You can convert your PowerPoint into videos using authorSTREAM's PPT to Video feature. All you need to do is jut to upload your presentation on authorSTREAM and convert it into a video. You can convert the video into multiple formats, like FLV, MP4, AVI, etc., download it or even send it to YouTube directly. Here are all the details about this feature http://www.authorstream.com/powerpoint-to-video/
Further, to your Facebook query, again - authorSTREAM allows you to upload and share your PowerPoint presentations from Facebook itself, and that too for free. You can check about that here http://blog.authorstream.com/2013/04/bringing-presentations-to-facebook-wall.html

Microsoft has a tutorial on there Office site here:
If you are using powerpoint 2010, Goto File> Save and Send> Create Video ! And you can create video! :D
Is there a fb app which can do this with share option?
