  # This an example configuration file for initializing the quantization matrix.
  # Altogether 6 matrices for 4x4 blocks and 2 matrix for 8x8 blocks.
  # The values range from 1 to 255.
  # If first value of matrix is equal to 0, default values ("JVT") will be used
  # for that matrix.
  # If a matrix is completely omitted, it will be filled with 16s.
  #
  # Note: JM expects CHROMAU and CHROMAV to be specified separately, whereas
  # x264 forces them to use the same matrix. If U and V are specified to have
  # different matrices, only the first is used.
