The VideoLAN Forums

The SIF1 project was launched in the autumn of 2000, with the major goal of finding new approaches for video compression. We developed a new class of algorithms for image compression. Its working title is "SIF-conversion". This class of algorithms can be realized in a number of ways, and the total efficiency of the resulting compression engine depends on the method of realization chosen. During several years, we worked on different compression engines based on SIF conversion. The sixth compression core was found to be the best basis for realizing the new codec. It should be noted that it could be further improved since the developed engine represents a compromise between the compression efficiency obtained and the time spent on the engine development.
