    Some are combinations of common container formats and audio and video coding profiles, such as AVCHD and DivX formats. Although sometimes compared to DivX products, Xvid is neither a container format nor a video format, it is a software library that encodes video using specific coding profiles of the common MPEG-4 ASP video format. Those types ...

    en.wikipedia.org/wiki/Comparison_of_video_codecs

    Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats. The compression may employ lossy data compression, so that quality-measurement issues become important.

  5. Video file format - Wikipedia

    en.wikipedia.org/wiki/Video_file_format

    A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g. VP9 ) alongside ...

  6. Video coding format - Wikipedia

    en.wikipedia.org/wiki/Video_coding_format

    A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .

    Overhead. This is the difference in file-size between two files with the same content in a different container. Support for advanced codec functionality. Older formats such as AVI do not support new codec features like B-frames, VBR audio or VFR video natively. The format may be "hacked" to add support, but this creates compatibility problems.
