20-40 is a useful range (default: 26).
Lower values result in better fidelity, but higher bitrates.
Note that quantization in H.264 works differently from MPEG[124].
H.264's QP is on a logarithmic scale.
H.264's quantizer parameter (QP) is on a logarithmic scale.
As an example, the bitrate difference between QP=20 and QP=40
is about a factor of 10.
Useful quantizers in H.264 tend to be very large compared to MPEG[124].
