video x-sheet

I found a fantastic tap-dancing vid on YouTube that I’d like to use as an X-Sheet for some character animation in Blender. Is it possible to scrub a video…as a template…as when keyframing?

first, download the youtube video in a .avi, .mov, or .mpg format.
next, in the 3d view, goto the menu VIEW—> BACKGROUND IMAGE
click the little arrow next to the frames (so it will count the frames for you) and click auto refresh.
