Same Day Edit- It's a huge hit nowadays showing highlights during dinner reception of pre-ceremony and ceremony footage edited with your favorite song. I can't imagine all the stress that the videographers need to go through, but it will definitely make an impact. People are used to seeing a photo montage when they enter the wedding reception, but a same day edit- not only it will WOW your guests but will leave the room with memories to remember. Mark Von Lanken from Picture This Productions says,"The client actually pays you to show your work to hundreds of their closest family and friends. Remember, most people didn't get to see close shots of the bride and groom as they saw each other, the emotion in their faces as they exchanged their vows, the ring slipping on the finger,but a wedding-day edit—that's truly breathtaking."
