8K is a higher resolution standard than 4K. 8K resolution, or 8K UHD, is the current highest ultra high definition television resolution in digital television and digital cinematography. 8K refers to the horizontal resolution of 7,680 pixels, forming the total image dimensions of (7680×4320), otherwise known as 4320p.
8K UHD has twice as many horizontal and twice as many vertical pixels as 4K UHD. So it has four times as many pixels in each direction and sixteen times as many pixels overall as Full HD.

8k resolution

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 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).


8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017. The feasibility of a fast transition to this new standard is questionable in view of the absence of broadcasting resources.
As of 2015, 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. By 2016 Red Digital Cinema Camera Company had delivered three 8K cameras in both a Full Frame sensor and Super 35 sensor.[6] 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.

First 8K Camera:

On April 6, 2013, Astro Design 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. 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.
