Test Clare codec AV1 vs X165 is underestimated because preset is good, bpg has veryslow.
Preset for X265 is:
0.ultrafast
1.superfast
2.veryfast
3.faster
4.fast
5.medium (default)
6.slow
7.slower
8.veryslow
9.placebo
Preset for VPX/AOM is:
0. rt + 37% quality
5. good (default) + 50% quality
9. best + max.63% quality
I associate it mistakenly with the parameter VPX "cq-level". So you could set for veryslow quality VPX best + max.63%.
No one probably doesn't know what effect it has value of quality "min-q". The first frame is always a big mistake for added value for codec VPX and AV1.
Interesting is also why each encoder VPX&AOM has a different parameter of quality.
FFmpeg has CRF.
What possesses Adobe plugin 1.003? Must enter function "cq-level". Changing the value of
quality means a change bitrate and the number of frames P. 37% is 2frames, 50% is 4 frames, 63% is 6 frames. It is a pity that libvpx isn't such fuction. Approached by a characteristic size of the frame to the X265. Changing
good to
best doesn't change the size of the bitrate, only the number of reference vectors in frame.
Edit: The function pass 2 is a falsification. There is no dynamic frame B. Analyzer video Elecard doesn't show that it has been implemented.
