Why video? Video brings back all the feelings. Being able to go back and watch your wedding brings back the sights, the sounds, and the sentiment; it brings back all the emotion and you get to relive that day over and over again.
What about those people you love that may have wanted to be there, but couldn't, Or maybe one day when one of your kids asks what your wedding day was like? Life has so many unexpected moments, and as dark as it sounds, you never know when you might lose someone. Imagine having a video of that person dancing or giving a speech at your event.
