Hot diggity dang, QNS is so good it hurts. And so slow it hurts. (Hey, there's always the tradeoff).

It's simply amazing in baseline. It brings CAVLC encoding to the efficiency of CABAC+trellis encoding. Well, you know. Pretty much. It's absolutely, utterly, ridiculously good on low-bitrate anime. No, no, forget AQ for now, this thing is already on the table. This is the first real progress baseline profile has seen since AQ. And that was the first ever, pretty much, since general RDO refinements. Usually CABAC and B-frames and trellis are required when quality is increased, but nobody seemed to care about where the quality hits home the most--in the lowest bitrates, for older computers or crappy decoders or handhelds or small screens and so on.

QNS is astounding. I can't believe something like tucking quant error in strange places does something this...marked. Is there any hope of a speedup??!
