Huffyuv is a very fast, lossless Win32 video codec. Huffyuv is intended to replace uncompressed YUV as a video capture format. It is fast enough to compress full-resolution CCIR 601 video (720 x 480 x 30fps) in real time as it's captured on my machine. Huffyuv also supports lossless compression of RGB data, so it can be used for the output of programs like VirtualDub.
