Powerpoint for Video
This is a crazy easy way to create video from existing content and yet most folks do not know it is possible. You can record your Narration, annotation and interaction as you move through your slides and at the end you just choose File>Export>Video and Voila! It is done!
Watch this fun little example. The powerpoint has transitions and animations that are also recorded.
Hey, this is interesting too – inserting a screen recording INTO powerpoint from inside powerpoint.
