const REFINE_FINER: u32 = 3;Expand description
Quality index steps finer than the paint-over one a refined block is coded at
(VaapiEncoder::refines): on Intel’s iHD (N97) 1080p H.264 text beside a video went from
41.3 dB to 44.1, 45.4, and 47.1 at a constant quantizer at 0, 3, and 6 steps finer, where the
driver’s cleanup of the still screen reaches 46.2; at a constant rate, held to REFINE_REACH,
from 31.0 to 33.3 at 8 Mbit/s and from 19.0 to 21.1 at 2, the video unchanged.
