New H.265 twice as efficient as H.264!

I don't fully agree, there is subjective and objective but there is also ignorance and knowledge. I never trust early subjective results not because there is anything wrong with it but usually when you change something (resolution, compression schemes, encoders....) things will be different and so people are ignorant. What I mean is that my guess with H.265 they found ways to improve issues that existed with H.264 (that is usually the definition of "efficient"). Anyone used to H264 (and good for such a test) will be knowledgeable with PQ issues of h.264 over compression, now if h265 fixes those issues but causes issues else where (can't pay Peter without robbing Paul) the person at this time might not have the experience to judge them as critically.
