Music video
The official music video for "Human" premiered on January 3, 2014 and was uploaded to Perri's YouTube account the following day. The video was directed by Elliott Sellers and features Perri as a robot sitting in a white room, with close-ups of the mechanics working inside of her body. As Perri begins to move, various body parts are shown to be bionic. Towards the end of the video, Perri begins to transform from a machine into a human as sparks fall behind her; her tattoos reappear as a symbol of her individuality and her robotic heart begins to pump fluid around her body.
