Since the 1860's, when photography first became possible, weddings have been recorded by still photographers. You've probably looked at the photo albums which preserve the memory of their parent's wedding. Unanswered by the photos are questions such as "how did Mom manage that huge train as she walked down the aisle?" "Was Dad able to bend over in his stiffly starched shirt?" "Was their first dance as graceful as their dancing today?"
Not all videographers have the same shooting/editing styles and skills. Many videographers have streaming video samples on their website so you can decide the style you like.
