Log:
tell that x264's crf gives better results than qp,
so crf should be prefered over qp

 H.264's quantization parameter (QP) is on a logarithmic scale.
 The mapping is approximately H264QP = 12 + 6*log2(MPEGQP).
 For example, MPEG at QP=2 is equivalent to H.264 at QP=18.

 The scale is similar to QP.
 Like the bitrate-based modes, this allows each frame to use a
 different QP based on the frame's complexity.
