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 matching the plane of eyesight and normalized by cinema and television, which trace their lineage from the proscenium theatre and Western easel painting traditions.^[1][2]

Vertical video has historically been shunned by professional video creators, because it doesn't 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 Periscope, which use the more mobile-friendly portrait format, have led to an increase in the production of vertical videos by advertising companies.^[3]

Historical usesEdit

Vertical filmmaking has aesthetic roots reaching back at least to the tall painted frescoes and stained-glass windows of Christian churches.^[4] The world’s first moving images of a cat (Falling Cat, Étienne-Jules Marey, 1894) were shot vertically. When the first motion picture screenings were held in 1895 however, the format was standardised horizontally (though at 4:3 aspect ratio, the images were closer to a square format than to widescreen). Noting that the new cinematic art had taken on the old strictures of the theatre, on 17 September 1930 Russian filmmaker and theorist Sergei Eisenstein addressed the Technicians Branch of the Academy of Motion Picture Arts and Sciences in Hollywood, calling for a cinema screen of variable aspect ratio (a "dynamic square"), one which would be able to cope with whatever compositional format the filmmaker chose, including a vertical framing.^[1] He lost the argument to a screen format standardised at a new Academy ratio (1.375:1) and vertical filmmaking has largely remained confined to experimental artists of the Expanded Cinema^[5] movement, which flourished during the 1960s and 70s. It also made appearances in various Worlds Fairs expositions such as In the Labyrinth^[6] in Montréal in 1967.

If artists working with cinematic film were constrained by physical limitations from tipping the apparatus, the video medium made rotating the camera and/or projector somewhat easier. Artist Bill Viola frequently employs tall-screen video. In 1984, musician and artist Brian Eno created Thursday Afternoon, a series of "video paintings" presented in vertical format.

By 2013 a number of independent film and video makers had made the creative jump to vertical formats for narrative films^[7] despite the limitations of using professional capture and projection apparatuses in vertical orientation.^[8] The first festival of specially commissioned tall-screen films, Sonic Acts' Vertical Cinema,^[9][10] was screened at Kontraste Dark As Light Festival in Austria in October 2013;^[11] whilst the world's first open competition for vertical film & video, the Vertical Film Festival^[12] was held one year later in Katoomba, New South Wales, Australia. Both organisations project onto large-format vertical cinema screens in suitably tall-roofed venues, but there have also been a number of online initiatives^[13] to encourage filmmakers to explore the creative potential of the vertical frame, as well as dedicated groups and channels on Vimeo.^[14] Similar exhibits took place in March 2015 at South by Southwest in Austin, Texas^[15] and in November 2016 at the Vertifilms festival in Prague.^[16]

Embrace of vertical videoEdit

Vertical video has presented significant challenges to video publishers, as many of them have been traditionally geared for horizontal video. In October 2015, social video platform Grabyo, which is used by major sports federations such as La Liga and the National Hockey League (NHL), launched technology to help video publishers adapt horizontal 16:9 video into mobile formats such as vertical and square.^[17]

Mary Meeker, a partner at Silicon Valley venture capital firm Kleiner Perkins Caufield & Byers, highlighted the growth of vertical video viewing in her 2015 Internet Trends Report - growing from 5% of video viewing in 2010 to 29% in 2015. Vertical video ads like Snapchat's are watched in their entirety nine times more than landscape video ads.^[18] Snapchat, DMG Media and WPP plc formed a content marketing agency called Truffle Pig in June 2015 that would be focused on creating content for vertical screens.^[19] By 2015, vertical video was rapidly supported by many major social platforms including Facebook and Twitter.^[20] YouTube introduced a vertical video viewing format compatible with mobile screens for Android in 2015; the new format was rolled out to all mobile devices two years later.^[21]

By the late 2010s, many online video platforms began embracing the use of vertical video due to the growing use of mobile devices. In 2018, Instagram launched a vertical video application, IGTV.^[22] The same year, YouTube introduced the capability for vertical video without black bars on its desktop website and in social media embeds.^[21] YouTube also unveiled a new vertical video ad format in 2018, saying “more than 70 percent of YouTube watch time happens on mobile devices”.^[21] In March 2018, streaming media company Netflix announced the introduction of vertically-oriented 30-second previews of shows and movies to its platform; the company also cited the use of mobile devices as inspiration.^[23]

Capitalizing on the rise of smartphones, some music artists began releasing platform-exclusive vertical music videos.^[24] These vertical videos are often shown on Snapchat's "Discover" section or within Spotify playlists.^[25]
