MX4 Advanced Video Compression Technology
The Multicast Labs compression engine, MX4, represents a breakthrough in compression technology.
There are two secrets that are the foundation for a host of benefits. First, the compression engine utilizes several break-throughs in vector and matrix math that dramatically reduces file sizes. The second is a set of break-throughs that optimize the interaction between the compression engine and the operating environment.
Together, with a number of other innovations, the MX4 compression engine offers:
Technology Comparison
In looking at video compression technologies people normally look at the PSNR data for a given video clip at various bit rates. Here is a sample of a test run on the Matrix clip for both MX4 and the best H.264 codec.
