Snow (codec) 1883652 220298774 2008-06-19T04:54:47Z WuBot 7192839 robot Modifying: [[de:Snow (Codec)]] '''Snow''' is an experimental [[video codec]] developed by [[Michael Niedermayer]] for the [[FFmpeg]] package. It can compress video either [[Lossy|lossily]] or [[Lossless|losslessly]]. Snow implements [[Wavelet compression|wavelet-based compression]], aiming for good image quality at very low [[bitrate]]s. It is [[open source]] licensed under the [[LGPL]]. ==Features== Snow is similar to [[Tarkin (codec)|Tarkin]], [[Dirac (codec)|Dirac]], and numerous other [[wavelet compression|wavelet-using codecs]]. Technical details can be found in the [http://svn.mplayerhq.hu/ffmpeg/trunk/doc/snow.txt?view=co snow.txt] file included in the [[ffmpeg]] source package. Another characteristic of snow is the usage of an intelligent and very efficient version of [[range encoding]]. [[FFmpeg]] aims to get the [[codec]] to become a [[Request for Comments]] (RFC). Therefore, a version 1.0 has to be finished. The documentation is started in [http://svn.mplayerhq.hu/ffmpeg/trunk/doc/snow.txt?view=co snow.txt]. Some Snow users (or potential ones) offered [http://www.ffmpeg.org bounty] to get the specification and implementation ready for version 1.0. ==Programs Using Snow== The following open-source video editing programs can encode to Snow format: *[[FFmpeg]] *[[Avidemux]] *[[LiVES]] *[[MeGUI]] *[[VirtualDubMod]] with [[ffdshow]] tryouts *[[MEncoder]] ==See also== {{Portal|Free software|Free Software Portal Logo.svg}} *[[Avidemux]] *[[FFmpeg]] *[[LiVES]] *[[MPlayer]] *[[VLC media player]] ==External links== *[http://forum.doom9.org/showthread.php?s=&threadid=84593 Snow discussion on the Doom9 forums] *[http://ffmpeg.mplayerhq.hu/ FFmpeg] *[http://svn.mplayerhq.hu/ffmpeg/trunk/doc/snow.txt?view=co FFmpeg's documentation on snow] {{free-software-stub}} {{Compression Software Implementations}} {{Compression Formats}} [[Category:Video codecs]] [[Category:Free multimedia codecs, containers, and splitters]] [[de:Snow (Codec)]] [[fr:Snow (codec)]] [[ja:Snow (コーデック)]] [[pl:Snow (kodek)]]
