Tim, I certainly agree that more than one videocamera is much better. If you could borrow another hd cam and tripod, place this in a position that you have scouted hopefully at the rehearsal. Start it rolling just before starting to shoot with the other to catch a better view of one of the Bride & Groom while on the alter while your other cam that you are actively shooting has a view to the other, both cams on tripods and rolling during the ceremony. Keep yourself out of the shot as much as possible. It is possible to shoot with one cam, takes lots of planning, but very difficult to get every shot. Two cameras much better especially if you can find someone to frame the shot on the other cam. Good luck. Keep shooting, shooting, shooting.
