MSU Lossless Video Codec is a lossless video compressor for AVI files written by Dmitry Vatolin, Dmitry Popov and Sergey Putilin. The codec is free for non-commercial use. The authors claim the codec gives the highest compression ratio in the lossless video compression field. The results are very interesting, you can see codecs comparison on the web site. If the source colorspace is RGB, you can opt for YUV conversion to achieve better results. Integrated denoising algorithms can help improving further the compression ratio. The codec also supports interlaced input.
