I just wrote a post in my web site: dvplace.com where I pine that I do not particularly like the production aspect of video. I like the edit where it is dark and lonely and it is just you and the story a cuddled up next to the glow of the computer screen.
However, I do like the production when I come home and feel that it went really well. However however, many of these times when I get to edit that particular footage it is not as good as I thought. Sometimes the opposite is true--when I get home and think the day was a disaster and then I see some really nice stuff.
I must say that both scenarios happen usually when I am shooting with a team without a monitor which I now refuse to do.
Anyway, the most detailed producer, armed with an armful of storyboards and shot lists can screw things up if they do not make themselves aware of the organics of the moment. Great things happen before or after "roll tape!" and off screen.
In documentaries it is even more so. Each of us will concentrate on the one or two needed things we need and then many cases lose really nice presents of happenstance. We return home happy that we "nailed our shot" only to find that later, in the edit, the "shot" really wasn't all that important to nail, and we missed the good parts. You change story slightly, add VOs, add emotional music and problem fixed. But the problem is not fixed for us. We watch and remember and we know what was covered up. It should make us more aware.
