From Morgan Multimedia:
Morgan M-JPEG is a video codec. This third version is particularly optimized for Intel and AMD last generation CPU and Windows XP and 2000 operating systems but it is even fully optimized for older CPU and older Windows versions. It also takes full advantage of multi-core/processors systems. It is more accurate and up to 5x faster than the previous version. Morgan M-JPEG codec exploits all the power of Intel and AMS CPUs.
