A vertical video is a video created either by a camera or computer that is intended for viewing in portrait mode, producing an image that is taller than it is wide. It thus sits in opposition to the multiple horizontal formats normalised by cinema and television, which trace their lineage from the proscenium theatre, Western landscape painting traditions,[1] and human visual field.[2]
Vertical video has historically been shunned by professional video creators because it does not fit the aspect ratio of established moving image forms, such as film and television, as well as newer web-based video players such as YouTube, meaning that black spaces appeared on either side of the image. However, the popularity of mobile video apps such as Snapchat and especially TikTok, which use the more mobile-friendly portrait format, have led to an increase in the production of vertical videos by advertising companies.[3]
