VP8 is an open and royalty-free video compression format released by On2 Technologies in 2008.. Initially released as a proprietary successor to On2's previous VP7 format, VP8 was released as an open and royalty-free format in May 2010 after Google acquired On2 Technologies.
libvorbis – Lossy compression, implementation of the Vorbis format; developed by Xiph.Org Foundation. iLBC – Low bitrate compression, primarily voice; iSAC – Low bitrate compression, primarily voice; (free when using the WebRTC codebase) TTA – Lossless compression; WavPack – Hybrid lossy/lossless
FFV1 (short for FF Video 1 [1]) is a lossless intra-frame video coding format. FFV1 is particularly popular for its performance regarding speed and size, compared to other lossless preservation codecs, such as M-JPEG2000. [2] [3] [4] The encoder and decoder have been part of the free, open-source library libavcodec in the project FFmpeg since ...
XZ Utils can compress and decompress the xz and lzma file formats. Since the LZMA format has been considered legacy, [2] XZ Utils by default compresses to xz. In most cases, xz achieves higher compression rates than alternatives like zip, [3] gzip and bzip2. Decompression speed is higher than bzip2, but lower than gzip.
Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
Dirac (and Dirac Pro, a subset standardised as SMPTE VC-2) is an open and royalty-free video compression format, specification and software video codec developed by BBC Research & Development. [4] [5] [6] Dirac aimed to provide high-quality video compression for Ultra HDTV and competed with existing formats such as H.264. [3]
