There's already enough to worry about on that special day. Let the videography be the part you don't worry about.
My style of wedding videography is to capture everything that is real and important about the day. Amazing things don't need to be set up or coordinated They just happen. And usually the moments I look for are the small ones because they are the most important.
And don't worry about coverage. I am a very athletic person and love running from one place to another to get the best shots.
When a couple is comfortable with their choices, they can have a much easier and memorable day.
