Lots of old rules have already gone out the window in this new era of multiscreen video so, sure, why not release a music video that’s (ostensibly) captured entirely via FaceTime on an iPhone, with pop star Selena Gomez herself doing duty as her own camera operator? (The biggest trick missed here? If you’re going to release a vertical video, why not upload it without the black bars on either side so YouTube can dynamically format it to fit different screens?)
