pub const REFRESH_FINER: u32 = 3;Expand description
Quality index steps finer than the session’s own a capped constant quality’s refresh codes its
coarse blocks at (BlockLedger::refresh, Codec::refresh_index), so a predicted frame
refreshing them comes to what the uncapped session’s picture stands at: refreshing a 720p
page of text a scroll left coarse, libvpx’s VP8 and VP9 came to 44.8 and 41.7 dB against the
uncapped sessions’ 44.5 and 40.5, and NVENC’s H.264 to 41.1 against 38.8. x264 takes a step
more (X264_REFRESH_FINER in the software encoder).
