8K resolution refers to any screen or display with around 8000 pixels width. 8K UHD, also known as Full UHD, FUHD, or Full Ultra HD is the current highest ultra high definition television (UHDTV) resolution in digital television, digital cinematography and digital signage. 8K in 8K UHD refers to the horizontal resolution of 7,680 pixels, forming the total image dimensions of (7680×4320), also known as 4320p, which refers to the vertical resolution.[1]
8K UHD has twice as many horizontal and twice as many vertical pixels as 4K UHD, as well as four times the linear resolution of 1080p (Full HD), and six times the linear resolution of 720p. 8K displays are able to produce images with such smooth gradients and high levels of sharpness that objects shown can appear even more realistic than in real world. This phenomenon is referred to as hyperrealism.[2]
High-resolution displays such as 8K allow for each pixel to be indistinguishable to the human eye when viewed at a typical distance from the screen. 8K resolution can also be used for the purpose of creating enhanced lower resolution videos through a combination of cropping techniques and/or with downsampling[3] techniques used in video and film editing. Resolutions such as 8K allows filmmakers to shoot in a high resolution with a wide lens or at a further distance, in the case of potentially dangerous subjects (such as in wildlife documentaries), by being able to zoom and crop digitally in post-production. The technique involves taking a portion of the original 8K image and cropping it to match a smaller resolution such as the current industry standard for high-definition televisions (4K, 1080p, and 720p).[4]
8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017.[5] The feasibility of a fast transition to this new standard is questionable in view of the absence of broadcasting resources.[6] It is predicted that 8K-ready devices will still only account for 3% of UHD TVs by 2023 with global sales of 11 million units a year.[7] However, TV manufacturers remain optimistic as the 4K market grew much faster than expected, with actual sales exceeding projections nearly 6-fold in 2016.[8]
As of 2018, few cameras had the capability to shoot video in 8K, with NHK being one of the only companies to have created a small broadcasting camera with an 8K image sensor.[3] By 2018 Red Digital Cinema camera company had delivered three 8K cameras in both a Full Frame sensor and Super 35 sensor.[9] Until major content sources are available, 8K is speculated to become a mainstream consumer display resolution around 2023 as mentioned in UHD forum Phase-B recommendations. Despite this, filmmakers are pushing demand for 8K cameras due to their ability to capture better 4K footage.
Japan's public broadcaster NHK was the first to start research and development of 4320p resolution in 1995. The format was standardized by SMPTE in October 2007, Interface standardized by SMPTE in August 2010 and Recommended as the international standard for television by lTU-R in 2012. Followed by public displays at electronics shows and screenings of 2014 Winter Olympics in Sochi and public viewings in February 2014 and the FIFA World Cup in Brazil in June 2014 using HEVC with partners AstroDesign and Ikegami Electronics.[10][11][12]
On January 6, 2015, the MHL Consortium announced the release of the superMHL specification which will support 8K resolution at 120 fps, 48-bit video, the Rec. 2020 color space, high dynamic range support, a 32-pin reversible superMHL connector, and power charging of up to 40 watts.[13][14][15]
On March 1, 2016, The Video Electronics Standards Association (VESA) unveiled DisplayPort 1.4, a new format that lets the use of 8K resolution (7680×4320) at 60 Hz with HDRR and 32 audio channels through USB-C.[16]
On January 4, 2017, the HDMI Forum announced HDMI 2.1 featuring support for 8k video with HDR, will be "released early in Q2 2017".[17]
On April 6, 2013, Astrodesign Inc. announced the AH-4800, capable of recording 8K resolution. In April 2015 it was announced by Red that their newly unveiled Red Weapon VV is also capable of recording 8K footage. In October 2016 they announced two additional 8K cameras, Red Weapon 8K S35 and Red Epic-W 8K S35.[18] The Red Weapon Dragon VV has been discontinued as of October 7, 2017, when Red unveiled the Red Weapon Monstro VV, their fourth camera capable of shooting 8K, with additional improvements in dynamic range and noise reduction, among other features.
In 2007, the original 65 mm negative of the 1992 film Baraka was re-scanned at 8K with a film scanner built specifically for the job at FotoKem Laboratories, and used to remaster the 2008 Blu-ray release. Chicago Sun-Times critic Roger Ebert described the Blu-ray release as "the finest video disc I have ever viewed or ever imagined."[19] A similar 8K scan/4K intermediate digital restoration of Lawrence of Arabia was made for Blu-ray and theatrical re-release during 2012 by Sony Pictures to celebrate the film's 50th anniversary.[20][21] According to Grover Crisp, executive VP of restoration at Sony Pictures, the new 8K scan has such high resolution that when examined, showed a series of fine concentric lines in a pattern "reminiscent of a fingerprint" near the top of the frame. This was caused by the film emulsion melting and cracking in the desert heat during production. Sony had to hire a third party to minimise or eliminate the rippling artifacts in the new restored version.[20]
On May 17, 2013, the Franklin Institute premiered To Space and Back, an 8K×8K, 60 fps, 3D video running approximately 25 minutes. During its first run at the Fels Planetarium it was played at 4K, 60 fps.[22]
In November 2013, NHK screened the experimental-drama short film "The Chorus" at Tokyo Film Festival which was filmed in 8k and 22.2 sound format.[23]
On May 1, 2015, an 8K abstract computer animation was screened at the Filmatic Festival at the University of California, San Diego. The work was created as an assignment in the VIS 40/ICAM 40 Introduction to Computing in the Arts class taught at UCSD by Associate Teaching Professor Brett Stalbaum during the winter quarter of 2015, with each student producing 300 8192×4800 pixel frames. The work's music soundtrack was composed by Mark Matamoros.[24][25]
On January 6, 2016, director James Gunn stated that the 2017 film Guardians of the Galaxy Vol. 2 would be the first (feature) film to be shot in 8K, using the Red Weapon 8K VV.[26] Villain (2017) is the first Indian film to be shot completely in 8K resolution.
Japanese public broadcaster NHK began research and development on 8K in 1995, having spent over $1 billion on R & D since then.[27] Codenamed Super Hi-Vision (named after its old Hi-Vision analog HDTV system), NHK also was simultaneously working on the development of 22.2 channel surround sound audio. The world's first 8K television was unveiled by Sharp at the Consumer Electronics Show (CES) in 2012.[28] Experimental transmissions of the resolution were tested with the 2012 Summer Olympics, and at the Cannes Film Festival showcasing Beauties À La Carte, a 27-minute short showcased publicly on a 220" screen, with a three-year roadmap that entails the launch of 8K test broadcasting in 2016, with plans to roll out full 8K services by 2018, and in time for the 2020 Summer Olympics.[29] On December 1, 2018, NHK launched BS8K, a broadcast channel with 8K capability.[30][31]

8K UHD is a resolution of 7680 × 4320 (33.2 megapixels) and is one of the two resolutions of ultra high definition television, the other being 4K UHD.[32] In 2013, a transmission network's capability to carry HDTV resolution was limited by internet speeds and relied on satellite broadcast to transmit the high data rates. The demand is expected to drive the adoption of video compression standards and to place significant pressure on physical communication networks in the near future.[33]
8K UHD has four times the horizontal and vertical resolution of the 1080p HDTV format, with sixteen times as many pixels overall.
8K fulldome is a resolution of 8192×8192 (67.1 megapixels) and is the resolution of top-end modern projection for hemispherical fulldome theatres often seen in planetaria.
10K resolution is horizontal resolution of around 10,000 pixels. This resolution is expected to be used in computer monitors, and is not a standard format in digital television and digital cinematography, which feature 4K and 8K resolutions.

Aoi (song)"Aoi" (English: "Blue", Japanese pronunciation: [aoi]) is a song by Japanese band Sakanaction. Used as the 2013 theme song for NHK's broadcasts of professional soccer matches, the song was one of two promotional singles from their sixth studio album Sakanaction (2013). Sakanaction wrote the song specifically for NHK, taking inspiration from soccer, and from the associations of the word blue in Japanese, due to the colors use as the color of the Japan national football team.
Released as a bonus on iTunes for pre-ordering Sakanaction on February 27, 2013, the song was used to promote the album on Japanese radio stations. It peaked at number 27 on the Billboard Japan Hot 100 chart a week after the release of Sakanaction. Critically, CDJournal reviewers responded positively to the song, believing the guitar-based rock, dance beat and vocal choir showed off a signature style of the band.
In 2015, a musical presentation using the song was created by NHK Media Technology and NHK Enterprises, shown in 3D with an 8K resolution and 22.2 surround sound. It was unveiled at the 2015 Media Technology! exhibition in Shibuya in November 2015.

Canon EOS 5DSThe Canon EOS 5DS and EOS 5DS R (known as the EOS 5Ds and EOS 5Ds R in Japan) are two closely related digital SLR cameras announced by Canon on February 6, 2015. Both are professional full-frame cameras with 50.6-megapixel sensors, the highest of any full-frame camera at the time of announcement. The only difference between the two models is that the sensor of the "R" version includes an optical filter that cancels out the effects of a standard optical low-pass filter. This distinction is roughly similar to that between Nikon's now-replaced D800 and D800E (with the E having a self-cancelling filter). Canon stated that both the 5DS and 5DS R will not replace the older EOS 5D Mark III, so therefore both the 5DS and 5DS R will have their new positions in Canon's DSLR camera lineup.
At the time of announcement, estimated prices were US$3,699.00 and US$3,899.00 (EOS 5DS and EOS 5DS R), with announced date of availability, through authorized Canon retailers, in June 2015.Despite the record-high pixel count and related storage and processing power, these cameras do not shoot 4K video or high frame rate 1080p video.Full-size demosaicked jpeg files from this camera occupy approximately 20 megabytes and exceed 8K resolution.
