vc2_quantisation_matrices

The vc2_quantisation_matrices package, provides both a standalone software tool and Python module for computing ‘default’ quantisation matrices for the SMPTE ST 2042-1 VC-2 professional video codec. Specifically, this software implements the procedure from section (D.3.2) for computing quantisation matrices which achieve noise-power normalisation.

You can find the source code for vc2_quantisation_matrices on GitHub.
