Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
Many of these resolutions are also used for video files that are not broadcast. These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed "Cinemascope", "21∶9" etc.), while the standard horizontal ...
Ultra HD Blu-ray (4K Ultra HD, UHD-BD, or 4K Blu-ray) [2] [3] is a digital optical disc data storage format that is an enhanced variant of Blu-ray. [4] Ultra HD Blu-ray supports 4K UHD (3840 × 2160 pixel resolution) video at frame rates up to 60 progressive frames per second, [ 4 ] encoded using High-Efficiency Video Coding . [ 4 ]
The main advantage of recording video at the 4K standard is that fine spatial detail is resolved well. [146] Individual still frames extracted from 3840×2160-pixel video footage can act as 8.3 megapixel still photographs, while only 2.1 megapixels at 1080p and 0.9 megapixels at 720p.
High-definition video which varies between 720p and 2k resolution uses about 0.9 GB (720p), 1.5 GB (1080p) and 3 GB (2k) per hour. Finally, 4K video, known as ultra-high-definition video, uses about 7.2 GB per hour. [17] [dubious – discuss] Netflix and YouTube are at the top of the list in terms of the most globally streamed video services ...
List of 4K video recording devices; 2K resolution – digital video formats with a horizontal resolution of around 2,000 pixels; 5K resolution – digital video formats with a horizontal resolution of around 5,000 pixels, aimed at non-television computer monitor usage
The resolution 3840 × 2160, sometimes referred to as 4K UHD or 4K × 2K, has a 16:9 aspect ratio and 8,294,400 pixels. It is double the size of Full HD (1920 × 1080) in both dimensions for a total of four times as many pixels, and triple the size of HD (1280 × 720) in both dimensions for a total of nine times as many pixels. It is the lowest ...
