Much like the Oort Cloud, Oort Editing is when you take scraps of video or film from a shoot and edit it together. Most commonly used on wedding videos to show the bride and groom what happened while they were getting ready and/or shit was hitting the fan. It is very much free form editing and has been made easier by the advent of nonlinear editors
"I loved that extra footage you put at the end of our wedding video!"
"Thanks, I just did a little oort editing."
