Don't worry about the requirement of the video, its just so you can turn the dial with your own real hand. You should be able to see the video very slightly (its 95% invisible!). Then just put your hand in front of the dial and shake it! The dial should turn more.
I just used the video camera blocks. QUESTION: At what time was the camera the most popular? ---<--->--- The Cam-Era! ---<--->---
