16:9 resolutions in comparison
Several 4K resolutions exist in digital television and digital cinematography. The term 4K refers to the horizontal resolution (instead of the vertical) of these formats, which are all on the order of 4,000 pixels.
Resolutions
4K Ultra HD
4K UHD is a resolution of 3840 pixels × 2160 pixels (8.3 megapixels, aspect ratio 16:9) and is one of the two resolutions of ultra high definition television, the other being 8K UHD which is 7680 pixels × 4320 pixels (33.2 megapixels). Both are aimed at consumer televisions. 4K UHD has twice the horizontal and vertical resolution of the 1080p HDTV format, with four times as many pixels overall.[1]
Digital cinema
The Digital Cinema Initiatives consortium established a standard resolution of 4096 × 2160 (8.8 megapixels, aspect ratio ~17:9) for 4K film projection. This is the native resolution for DCI-compliant 4K digital projectors and monitors; pixels are cropped from the top or sides depending on the aspect ratio of the content being projected. The DCI 4K standard has twice the horizontal and vertical resolution of DCI 2K, with four times as many pixels overall.
4K digital films may be produced, scanned, or stored in a number of other resolutions depending on what storage aspect ratio is used.[2][3]
On professional production, 4K/UltraHD content is produced from high-end film captured by 8K scanners (7680×4320 pixels) or 8K sensors cameras (7680x4320 pels) or 4K CGI (4096 × 2160 px). Content produced from digital cameras using "4K sensors" (3840 × 2160 px) is not considered 4K-Digital-Film/UltraHD but 2K[citation needed]
Streaming video
YouTube allows a maximum upload resolution of 4096 × 3072 (12.6 megapixels, aspect ratio 4:3).[4][5]
