Bricks are a new one to me, or is this just a slight variant on the tile technique?

There is a new article from BBC R&D

https://www.bbc.co.uk/rd/blog/2019-0...ssing-hevc-vvc

I can't find any reference but I assume they tested it with VTM 5.0.

Results looks, good especially for single pass and Streaming. I Still wish VVC will push further in bitrate reduction. For resolution I cared about, which is NOT 4K / UHD, I think the reduction was only 25%.

Nrr, another mean PSNR study, no subjective quality analysis. PNSR is the least well subjectively correlated metric we ever use.

Also, past studies have shown that libaom shows better PSNR but similar or slightly worse subjective quality than HEVC HM. A study that had PSNR and subjective data would let us see if AV1 is getting psychovisual improvements. The hope is libaom would be evolving to improve psychovisual quality even if it reduces PSNR.

I've converted it to PDF:

You can also get it from here.

So around 35% to 40% reduction.

Are there any similar test done for EVG?
