    Since September 2007, the FFmpeg Open Generator project has provided 8-bit VC-3/DNxHD encoding and decoding capabilities thanks to positive support from BBC Research, who pre-sponsored the screening, and Coudurier Baptiste, who presented. July 2011 FFmpeg is built with support for 10-bit encoding. DNxHD support [8] updated in stable version 0.5 of FFmpeg released March 10, 2009[9][So 10] video editors Nonlinear Linux Cinelerra and Kdenlive can be used on DNxHD.

    Technical Details

    DNxHD is very similar to JPEG. Each frame is independent and consists of DCT-vlc encoded coefficients.

    The header consists of several parts and can quantify 2048-bit data processor tables and provide. Each frame also generates two GUIDs and one timestamp. The frame header is often wrapped in big-endian double words. The actual frame data consists of grouped macroblocks using a method that is almost exactly the same as in JPEG: DC prediction plus variable-length codecs with a range of lengths to get another 63 coefficients.in.
