This is my first post here and I hope nobody will have a hard time understanding my bad English.
Anyway, as a Belgian wedding videographer , reading 2darts experience, I noticed that there's really no difference in all the problems you encounter with your first time shoot. Especially the part of hitting the record button and noticing that you actually put the camera on pause
This has happened quite often to me in the beginning of my "career", now it has become a habit of each time checking the text in my display to assure it's in record mode. Especially when everything has to go really fast you tend to forget checking your camera settings.
I usually work alone, but can also only agree that a multicam setup of a wedding is the best way to go, working alone does put a lot of stress on you because you get only one shot, one try to get it right. It takes some time and experience not to be afraid to take a position were you can get the best shot, and at the meantime not to become the main attraction. Most of the people in church still want to see the couple and not the back of an annoying videographer.

Another thing which has been pointed out by Marc was about the risk of unmanned camera's. To tell you the truth, I never ever leave my camera unattended. Especially when unmanned on a tripod with small children running around you don't have to imagine what would happen if the tripod would fall.
I even hold my camera tighter to me all day then I would do with my wife
Eventough the wedding day can be very stressful I love every bit of it. Especially when I'm driving home, after a 14-15hour working day I just can't wait capturing everything to my pc that I shot that day and then the most fun just begins.
I really like the enthusiasm in 2darts writing, this sets him apart from all the videographers who only do this to make a quick buck. Just reading how much effort he took to get his first try right I can only admire this. just keep that up if you ever want to do this full time.
