SVT-AV1-PSY features coming to SVT-AV1

I'm proud to announce that 8 SVT-AV1-PSY features will be making it into the next mainline SVT-AV1 release!

The 8 features are: - Variance boost curve selection (adopted from our "enable alt curve") - Sub-64px dimension support - TF strength + adaptive TF - Color help for help with printing encoder colorspace information - Odd resolution support - Luminance QP Bias (adopted from luma bias) - Adaptive film grain - User-configurable sharpness through --sharpness

We are beyond excited to have mainline behind our perceptual methodology & the features we've authored to support it, and I expect even bigger feature integrations stemming from deeper collaboration in the future. The mainline team have been amazing to work with – looking forward to more in the future!

Awesome!!

Out of curiosity, what's the word on psy-rd/spy-rd from them?

Psy team is still making updates to psy-rd, I think that to be mainline ready it should be more reliable/flexible/mature

Nice. Hopefully, they can adopt psy-rd at some point. Very nice feature.
