Snow is a lossy and lossless video codec, (originated in the FFmpeg project). Snow features wavelet transform, overlapping block-based motion-compensation, and entropy coding that is not based on Huffman coding. It shares with Dirac the choice of wavelets but it is quite simpler and with less optional features. At the present the ffmpeg implementation of Snow is partially optimized for x86, AMD64 and PPC and is only suited for high-end systems.

Snow has not reached version 1.0 and thus is in an experimental state as of August 2008. There are some tasks left for a final 1.0 version.
