That’s a lot of frames. Regular video is anywhere from 24 to 60 frames a second. 500 frames is seriously high speed stuff.

I would be flat out embarrassed to see my cast at 500 frames a second. Not Jason Borger, though. He was Brad Pitt’s casting double in a River Runs Through It, and one of the best casters in the business. Borger teamed up with Grunde Lovoll Ph.D to get this amazing video, which clearly shows the multiple parts of the cast. From the backcast to loop formation. For all you casting wonks out there many more of these videos can be seen at here (url below) with different parts of the cast broken down in super slow-mo.
