The two extremes of picture quality are defined as follows:
• White noise, where the bit rate estimate will always exceed the maximum bit rate
and the encoder will therefore output the maximum bit rate
• Black video where the floor for the bit rate value will be the minimum bit rate.

6.3.4.2 Target Quality
The Target Quality configuration does not set the average bit rate, it only biases the
bit rate towards a direction. For example, a lower target quality will require a lower
bit rate for a demanded content.
