Quantization

The Q (Quantization) parameters are quality settings, where 1 is lowest quantization and highest
quality (and more bits used), and 112 is the highest quantization and lowest quality (and less bits
used).

The rate control mode determines the required parameter.

QMin: Minimum quantization that is used for encoding.

QMax: Maximum quantization that is used for encoding.

QInitial: Quantization value used in the first encoded frame. In Constant Q mode this value
shall remain fixed for all frames.

The figures below show the CBR and Constant Q modes of the MPEG-2 encoder.
