SheerVideo

SheerVideo was a family of proprietary lossless video codecs developed by BitJazz Inc. to enable capture, editing, playback, and archival of professional-quality lossless video formats in real time on low-power inexpensive hardware such as laptop computers and video cameras. As tested on a standard set of Kodak images used in image compression research, SheerVideo's average compression ratio is over 2:1 for real-world footage. Because SheerVideo generally runs faster than a computer system's data throughput speed, this compression power means that SheerVideo runs more than twice as fast as uncompressed data while taking less than half the storage space. It no longer appears to be under development, and the last available version does not appear to be compatible with the current Mac OS.
