A YouTube video statistics with AVC (H.264) video codec and Opus audio format. In 2009, the HTML5 working group was split between supporters of Ogg Theora, a free video format which is thought to be unencumbered by patents, and H.264, which contains patented technology.
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. If the final video resolution is reduced to 2K from a 4K recording, more detail is apparent than would have been achieved from a native 2K recording. [146]
Unity 3.0 launched in September 2010 with features expanding the engine's graphics features for desktop computers and video game consoles. [16] In addition to Android support, Unity 3 featured integration of Illuminate Labs' Beast Lightmap tool, deferred rendering, a built-in tree editor, native font rendering, automatic UV mapping , and audio ...
A similar technique was used in the 1993 video game Doom, which had a "low detail" mode that only rendered every other column of pixels to improve performance. [ 3 ] [ 4 ] Checkerboarding also bears a resemblance to interlaced video , where every frame is split into two fields, also halving the amount of pixels that has to be rendered or ...

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.
The video sequences were encoded using the HM-12.1 HEVC encoder and the JM-18.5 H.264/MPEG-4 AVC encoder. The comparison used a range of resolutions and the average bit rate reduction for HEVC was 59%. The average bit rate reduction for HEVC was 52% for 480p, 56% for 720p, 62% for 1080p, and 64% for 4K UHD. [127]
