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]]
