Does the couple have any say as to how their wedding videotape is edited?
When you are interviewing videographers, ask about this. A few may let you watch the pre-edited video and decide what you want left in (the entire ceremony, the wedding party's entrance, the first dance, and so on) or taken out (off-color remarks by guests, friends, or relatives, or you captured doing embarrassing things). Most will simply let you give them a general idea of what you want left in and taken out and will do the actual editing themselves.
