@alyx depending on who does the tests av1 is 30% smaller than h265 but i think this is at maximum oven mode which is very slow

@icedquinn
Faster than vp9 is good (by any margin), but only 30% smaller than h265 is not that impressive for 2x slower. Not impressive for me anyway, because h265 itself is not an amazing benchmark to compare against.

@alyx apparently the mpaa already has another newer thing than h265 that av1 is worse than but it's still a ways out from being fielded.

av1 was kinda always about getting off the plantation more than anything though.

h265 and the next is about cramming super hd deluxe titty micropore cam on to a spinny disk.

@icedquinn
h265 and whatever comes after it are probably both shit. I remember trying to read into what h265 had different over h264, and it was mostly how big the grid of pixels that it was analyzing was, and how it would merge them as a single color if they were close enough. Basically h265 compresses 4k video better by creating more blockiness than h264. Not impressive at all.

@alyx i tried looking in to what av1 actually does and there was one description about how it works like jpeg-2000 but with motion prediction and flexible chunking.

or something.

i looked in to the bitstream and the spec is massive bordering on general computation device.

@icedquinn
All video codecs have motion prediction to some degree. Maybe AV1 has a different algorithm that is better, but that's a basic video codec feature since divx/xvid days (it's what causes that weird color smear glitch when video gets corrupted).

As for flexible chunking, I don't think that's a new thing either, although I might be confusing what it's referring to. Haven't looked into video codecs for so long, that I've forgotten some of the jargon.

@alyx av1 isn't meant to push envelopes. it's meant to be as good but get off the patent fee vig.

@icedquinn
The next big video codec to gain mainstream attention won't be open source/patent free, no matter how good it is. Even if av1 is significantly better than h266 (or whatever comes after h265) it won't matter if av1 doesn't get the lobbying behind it.
