Snow (codec)
From Wikipedia, the free encyclopedia
Snow is an experimental video codec developed by Michael Niedermayer for the FFmpeg package. It can compress video either lossily or losslessly. Snow implements wavelet-based compression, aiming for good image quality at very low bitrates. It is open source licensed under the LGPL.

[edit] Features
Snow is similar to Tarkin, Dirac, and numerous other wavelet-using codecs.
Technical details can be found in the 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 snow.txt. Some Snow users (or potential ones) offered bounty to get the specification and implementation ready for version 1.0.
[edit] Programs Using Snow
The following open-source video editing programs can encode to Snow format:
