It uses wavelets, motion compensation, and arithmetic coding, and aims to be competitive with other state-of-the-art codecs. The Open Source implementation provides a C++ library with an encoder and decoder. MediaCoder has included Dirac video encoder 0.7.0. Changes of Dirac 0.7.0
  • Added support for Constant Bit Rate Coding.
  • Improved quality of encoded pictures at low bit-rates and
  • Improved motion vector data partitioning to allow for
