ICQ is Intelligent Constant Quality. It will use the initial QP vaule of icq-quality-factor to adjust QP at MB level intelligently to improve subjective quality. QVBR is Quality defined VBR. It will use qvbr-quality-factor to adjust QP for each MB to get enough quality picture without waste of bits.
