The compression ratio (that is, the size of the compressed file compared to that of the uncompressed file) of lossy video codecs is nearly always far superior to that of the audio and still-image equivalents. Video can be compressed immensely (e.g., 100:1) with little visible quality loss

480p is the shorthand name for a family of video display resolutions.The p stands for progressive scan, i.e. non-interlaced.The 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4 ⁄ 3 = 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility) [1] pixels for an approximate 16:9 aspect ...
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.
2K resolution is a generic term for display devices or content having a horizontal resolution of approximately 2,000 pixels. [1] In the movie projection industry, Digital Cinema Initiatives is the dominant standard for 2K output and defines a 2K format with a resolution of 2048 × 1080.
6K resolution refers to display formats with a horizontal resolution of around 6,000 pixels and a vertical resolution of around 3,000 pixels. [1] But the exact number may vary depending on the aspect ratio and pixel shape. 6K resolution is higher than 4K resolution, which has about 4,000 pixels horizontally, and lower than 8K resolution, which has about 8,000 pixels horizontally.
High-definition video (HD video) is video of higher resolution and quality than standard-definition. While there is no standardized meaning for high-definition , generally any video image with considerably more than 480 vertical scan lines (North America) or 576 vertical lines (Europe) is considered high-definition.
While 16:9 (1.7 7:1) was initially selected as a compromise format, the subsequent popularity of HD broadcast has solidified 16:9 as perhaps the most common video aspect ratio in use. [7] Most 4:3 (1.3 3:1) and 21:9 video is now recorded using a "shoot and protect" technique that keeps the main action within a 16:9 (1.7 7:1) inner rectangle to ...
