Lower values result in better fidelity, but higher bitrates. Lower values result in better fidelity, but higher bitrates.
Note that quantization in H.264 works differently from MPEG[124]. Note that quantization in H.264 works differently from MPEG[124].
H.264's quantizer parameter (QP) is on a logarithmic scale. H.264's quantization parameter (QP) is on a logarithmic scale.
