const REFINE_RATE_HELD: f64 = 1.2;Expand description
The frame budgets the frames of a region refining nothing may average before it refines
nothing for REFINE_PAUSE frames: a rate control that already runs over its rate has none to
spare. Beside a video, VP8’s frames averaged 1.38 budgets at 2 Mbit/s, where refining took
the text to 25.5 dB against 29.6 by its cyclic refresh and 12% more bytes, and 0.76 at 8
Mbit/s, where it took the text from 33.5 to 42.6.
