Advanced usability options for output. The most frequently used parameters in this section pertain to colorimetry settings, useful when producing output that has to meet a given broadcast colorspace for display on television systems.
Nal-hrd is sometimes required for systems (in particular, some CableLabs variants), where a hard constant bitrate must be observed and reported in the data stream.
