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 Los Angeles and San Antonio. 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 Taylor 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. At the end, Swift and Sheeran appear and we realize that they are actually two different parents, arriving at the school to pick up their kids and take each of the children back to their respective homes. Jason Lipshutz from Billboard labelled the video as "impossibly adorable", while Ray Rahman from Entertainment Weekly compared the video's synopsis to Forrest Gump, but "much more gentle than that".
