SIF1 – 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.



    *Motion detection engine was restructured and optimized for multithreaded operation (up to 32 threads). In current code multithreaded optimization is done using a temporal scheme since the core of SIF transform is the last big unit of code that is not working in multithreaded mode.
    *Added multithreaded modes of an entropy codec operation (up to 8 threads). Thus, the decoder now have full multithreading support and supports decoding of streams with 80+ mbits bitrate.
    *Codec now supports vertical resolution that is not a multiple of 16.
    *Implemented different (in terms of speed & quality) motion detection engine presets.
    *Added checking for correct input. Now the decoder doesn't crash on corrupt or invalid files.
    *Added turbo first pass mode - about two times faster than second in two-pass mode.
    *New PsyRD extrapolation engine, used in the motion detection engine, is written. Due to this, another significant improvement in sharpness and detail of compressed image was achieved.
