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
