8 - 10 degree, a wide beam is fine for video but you need a tight beam in order to signal your buddy properly.

Yes we know that a narrow beam is best for signaling your buddy...we are talking about video. Posted under the Videography should have been a clue. Thanks anyway.
Depends on the angle of the lens you are using- you want interest ting sweeps of the lights and the lense coverage.
