The LR3 video was shot using four cameras. Two Sony EX1s were used for the shots of Jeff and me. A small Panasonic T700 was on an overhead boom to record an over the shoulder perspective, and a Canon 7D was used for various cut-aways.
We also did video screen captures on both computers, so there are in fact up to six separate video tracks available, though not all are used in any one sequence.
Audio is recorded using lapel mics, wirelessly, and the Editorol is a backup. We also recorded voice on the laptops while working, so we have multiple audio choices as well.
This is all mixed on multiple tracks on Final Cut.
