4K Ultra HD


4K Ultra HD[edit]

4K UHD is a resolution of 3840 pixels × 2160 lines (8.3 megapixelsaspect 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 lines (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.[5]Currently all 4K UHD televisions use a standard 5.1 sound system, with no moves towards 7.1 being publicized.

Digital cinema[edit]

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.[6][7]

Streaming video[edit]

YouTube allows a maximum upload resolution of 4096 × 3072 (12.6 megapixels, aspect ratio 4:3).[8][9]
Vimeo allows videos of this resolution to be uploaded as well.[10]
