const LEVEL_S: f64 = 4.0;Expand description
Seconds the finest quantizer such a session has coded the still screen at stands before its
rate control counts as done with the picture, where the session says its quantizer and does
not measure: at 0.25 Mbit/s at 1080p x265 takes a step finer every 2 to 8 s for a tenth of
a dB a second, and libvpx’s VP9 one every 6 s after its first ten, each for all of REFINE_S
at the full rate, where at 2 Mbit/s x265 takes one every 2 s for its first twenty.
