There was also some great data about VVC at the SMPTE Tech meetings in LA this week. Efficiency gains for objective metrics on HEVC HM are getting close to 30%, and the encoder is only about 1/5th slower. Subjective testing shows bigger gains than objective metrics predict. Theory is that the motion interpolation is a better match for the human visual system, so high QP motion artifacts aren’t nearly as objectionable. It’s always districting when things happen on a grid structure; our eyes are REALLY good at horizontal and vertical detail, and regular distributions.

Same track also showed that HEVC beats AV1 on subjective tests even

The goal of the same subjective quality as HEVC at half the bitrate looks within reach, given the bitstream has still more than a year to percolate. It might be more than 50% for UHD and higher resolutions.

(Although I still don’t think 8K video is going to really be a thing).
