Everything Has Changed [SEP] Music video
A music video for "Everything Has Changed" was released on Swift's VEVO channel on YouTube on June 6, 2013. It was directed by Philip Andelman and filmed in Oak Park, California at Media Creek Middle School and San Antonio, Texas. The video begins with two children who initially appear to be Swift and Sheeran when they were much younger, meeting each other on a bus to elementary school. Young Swift is played by Ava Ames. Throughout the video, the two children have their "youthful play", including painting their faces with crayons, pretending to be a princess and knight, and dancing with each other in the empty school gym.
