How can I show camera footage live on my Mac?

by on February 3, 2011

Q: I am hosting a conference in 2 weeks and want to broadcast the presenter LIVE on two screens in the ballroom. I have a MacBook Pro, 2 projectors, a Sony HD camera, 50 ft VGA cable (x2), a VGA adapter for my Mac, and a VGA splitter.

How can I show the camera footage live on the screens using my Mac?
