I've done 2 casual wedding videos and even just being casual is just a pain and then reliving the whole pain through editing is no fun and when you fine out you didn't get the right shot or something went wrong...I think wedding jobs are pure hell, survivable and a good way to make money if your good but you gotta have stamina. For video I like multicameras like nuts, if allot of stuff is happening in one area 3 cameras is nice to switch the angles up and ensure you get everything, of course make sure that your cameras do timecode or you'll probably just cry on import and go to bed (I lost timecode on a 3 camera shoot once and was up for 30hours straight...not cool). And pleasing the client is fun too....either way I'll probably end up doing other weddings just for the cash since I barely get paid but just go in prepared, theres no room for error.
