The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
Lagarith – Video codec designed for strong lossless compression in RGB(A) colorspace (similar to ZIP/RAR/etc.) libtheora – A reference implementation of the Theora format, based on VP3, part of the Ogg Project; Dirac as dirac-research, a wavelet based codec created by the BBC Research, and Schrödinger, an implementation developed by David ...
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 ...
[11] x264 won an independent video codec comparison organized by Doom9.org in December 2005. [12] The LGPL-licensed libavcodec by FFmpeg includes an H.264 decoder. It can decode Main Profile and High Profile video. It is used in many programs like in the free VLC media player and MPlayer multimedia players. FFmpeg can also optionally (set at ...

In a subjective video codec comparison released in August 2014 by the EPFL, the HM-15.0 HEVC encoder was compared with the VP9 1.2.0–5183 encoder and the JM-18.8 H.264/MPEG-4 AVC encoder. Four 4K resolutions sequences were encoded at five different bit rates with the encoders set to use an intra period of one second.
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 .
