Default 0 - Disabled --aq-mode Mode for Adaptive Quantization - 0:none - 1:uniform AQ - 2:auto variance - 3:auto variance with bias to dark scenes - 4:auto variance with edge information. Default %d --[no-]hevc-aq Mode for HEVC Adaptive Quantization. Default %s --aq-strength Reduces blocking and blurring in flat and textured areas (0 to 3.0). Default %.2f --qp-adaptation-range Delta QP range by QP adaptation based on a psycho-visual model (1.0 to 6.0). Default %.2f --[no-]aq-motion Block level QP adaptation based on the relative motion between the block and the frame. Default %s --[no-]sbrc Enables the segment based rate control. Default %s --qg-size Specifies the size of the quantization group (64, 32, 16, 8). Default %d --[no-]cutree Enable cutree for Adaptive Quantization. Default %s --[no-]rc-grain Enable rate-control mode to handle grains specifically. Turned on with tune grain. Default %s --ipratio QP factor between I and P. Default %.2f --pbratio QP factor between P and B. Default %.2f --qcomp Weight given to predicted complexity. Default %.2f --qpstep The maximum single adjustment in QP allowed to rate control. Default %d --qpmin sets a hard lower limit on QP allowed to ratecontrol. Default %d --qpmax sets a hard upper limit on QP allowed to ratecontrol. Default %d --[no-]const-vbv Enable consistent vbv. Turned on with tune grain. Default %s --cbqpoffs Chroma Cb QP Offset [-12..12]. Default %d --crqpoffs Chroma Cr QP Offset [-12..12]. Default %d --scaling-list Specify a file containing HM style quant scaling lists or 'default' or 'off'. Default: off --zones //... Tweak the bitrate of regions of the video Each zone is of the form ,,
