[SVT-AV1-PSY] A Handbrake project to natively integrate svt-av1-psy in place of svt-av1, with Linux, Windows and macOS support! (github.com)

Good morning my fellow video encoding afficionados.

As usual, I was trying to find interesting stuff on the web, and I finally did!

Someone in our wonderful AV1 enthusiast community has spent a lot of time working on natively adding svt-av1-psy to Handbrake; this is done through specific patches that add the additional functionality of svt-av1-psy in Handbrake.

This allows for Windows, macOS, Linux (Flatpak) and native Linux builds of Handbrake to be built with nearly complete svt-av1-psy support.

It's truly a great addition as it allows many more people to be at the leading edge of high fidelity AV1 encoding.

Note that these are based on Nightly Handbrake, but this shouldn't pose a problem.

Head over to the "Releases" page to find the full builds, CLI versions and even dynamic library replacement: https://github.com/Nj0be/HandBrake-SVT-AV1-PSY/releases

That'll be all from me. Thank you for your attention and have a great Saturday.

I don’t know what any of this means. Can someone translate?

Controls how "selective" the algorithm is when boosting superblocks, based on their low/high 8x8 variance ratio. A value of 1 is the least selective, and will readily boost a superblock if only 1/8th of the superblock is low variance. Conversely, a value of 8 will only boost if the entiresuperblock is low variance. Lower values increase bitrate. The default value is 6.
