Well, VP9 only has pframes still, afaik, so no problem.
but x264 have I,P,B,b ... so screenshoot will always fails to make comparison.

I deleted my samples, sadly, but VP9 was easily beaten by x264 visually (I tested a DVD source at 3 megabits to see if it will still have quality issues with that generous bitrate).
Like say psnr or ssim ... ;-)

The ratecontrol is probably faulty, select frames were even noticeably worse than VP8 with same settings.
No problem with constant quantizer. Anyway the RC for VP9 seem not so bad (OPSNR higher in two pass mode than constant quantizer mode mean generaly good RC).
