const REFINE_RISE: i32 = 2;Expand description
Quality index steps the rate control’s frames may come out coarser than before the region
started refining before its refined blocks a frame halve (or past REFINE_OVER); where they
come out no coarser, a quarter more. Dense 1080p text refined at 128 blocks a frame beside a
video at 8 Mbit/s ran x264’s row-level control past quantizer 51, where it scales every
macroblock offset toward nothing, and left the text at 42 dB; at 16 a frame it reached 48.
