SIF1 video codec is a free universal video codec. It's a multimedia compressor/decompressor which registers into Windows collection of multimedia drivers and integrates into any application using DirectShow and Microsoft Video for Windows. It's based on the original proprietary algorithm of compression.

This class of algorithms occupies the intermediate position between traditional algorithms and algorithms that divide source image in set of objects. In SIF-similar codecs, compression is put into effect at the expense of image to the set of basic elements - resampling patterns. During several years, we worked on different compression engines based on SIF transform. The sixth compression core was found to be the best basis for realizing the new codec. But that engine is just simplified prototype, on which practical realization of this new technology of compression is perfecting.

SIF1 codec is based on the SIF ore6 and several algorithms that increase the efficiency of moving image compression.
