On 21 May 2015, the band posted the audio video of the song on their Vevo account. The music video for the song was directed by Director X and was filmed at the University of Southern California on 22–23 May 2015 in Los Angeles. Talking about the video, Jesy Nelson also said to an interview in Capital FM that "we [the band] are acting which is exciting! They're like little mini movies which is exciting". Jade Thirlwall also said that "it's nothing like we've done before and it's like a movie". Just one day before its release, Leigh-Anne Pinnock posted on Twitter: "OMG! Can't believe the #BlackMagicVideo is live tomorrow on @Vevo_UK at 8am! So excited for you guys to see!" The video premiered online on the band's Vevo channel on 29 May 2015. Following the release of the video, the band posted several tweets on their account reacting to the fans' opinions for the music video. The video begins showing the campus, then introduces the band, who are dressed as nerds carrying their textbooks while exiting at a school building in the campus. During that, Jade suddenly falls off a pavement, causing also Leigh-Anne to fall also and Jesy avoided. They see a good looking male student (Mikey Grand) wave at them and become excited. However, he's actually waving to the beautiful and popular female student (Stefanie Michova) behind them, who nastily shoves them aside to approach the boy. The scene then changes to the library, where we see Jade take off her Beats headphones and search for a book. Out of nowhere, an old book falls on top of her head, unveiling some of its own powers. Later in the night, the girls open the book and use it to gain magical power. Perrie then turns her hair purple, Leigh-Anne has yellow fire powers, Jesy has blue powers, and Jade levitates her glasses. The girls change into their normal selves; becoming the real Little Mix, as some of the male students' jaws drop as the girls walk by. They then embarrass the spiteful girl from the previous day by magically causing her to constantly pass gas. She then runs away in humiliation to the bathroom, while the scene changes to a geeky boy being humiliated by four beautiful but vindictive girls. The band feels sorry for the boy, so they make the girls fall in love with him. The girls then walks down the hall as everybody stares, intertwined with a scene of the girls standing back to back as the camera circles them.
