And you, as a user, don't have to know
In the
bitrate-based encoding modes, like
1-Pass ABR or
2-Pass, the rate-control algorithm will pick the "right" qunatizers to hit the target average(!) bitrate that you have chosen.
By changing the "minimum/maximum quantizer" options you only restrict the interval of quantizers from which the rate-control algorithm can choose - which can easily lead to missing the desired average bitrate!
If, for example, you set both, the minimum and the maximum quantizer, to a value of 1, then you
force the rate-control algorithm to
always pick 1, regardless of the chosen bitrate
You would only limit the minimum (or maximum) quantizer, if you believe that the rate-control algorithm sometimes goes too high (or too low) for no good reason...
