I use video footage a great deal in my teaching as most of the students that I work with are visual learners.
The ZuiTube website is like a gigantic, well organised filing cabinet of student friendly material, covering a massive range of topics.
I go to ZuiTube to find material on every topic that I teach as well as for visuals based on students' special areas of interest. I can use the footage as motivators or rewards for working hard, as a calming activity when anxiety levels are escalating or after a meltdown to help a student regain equilibrium.
