What makes a good instructional video?

Video supports education in many areas and online courses regularly include instructional videos. Video transports the content both audibly and visually, creating a multisensory learning environment that is said to be particularly conducive to learning. The fact that multisensory learning environments can be beneficial to learning (and when it does so) has been investigated a lot of times in laboratory experiments. In practice, however, there is still uncertainty about what really makes a good video.

What's with the hype about videos in Social Media?

And apparently, the supply is matched by a corresponding demand. A company like Facebook would not place so much emphasis on videos if it hadn't come to the conclusion that this kind of content is particularly popular with users.
