Our most significant PSY micro-release is here with SVT-AV1-PSY v2.2.1-A!!! 🏆

PSY Updates

Features

  • Encoding with odd (non-mod2) dimensions is now possible
  • Encoding at resolutions lower than 64x64 is now possible, down to as small as 4x4

Quality & Performance

  • A new variance boost curve for Tune 4 has been introduced, optimized for still image encoding performance
  • Improved color reproduction & overall picture quality in Tune 4 & Tune 2 through chroma qindex scaling (similar functionality is already present in Tune 3)
  • Higher quality presets are available when encoding 16K
  • Default --chroma-qm-min has been updated to 8 (from 0)

Documentation

  • Updated Handbrake link to new, cross-platform Handbrake PSY builds

Bug Fixes

  • The version number should now be correct when building from an archive instead of cloning with git
  • AVIFs with dimensions exceeding 4K resolution should decode correctly in applications that previously refused to decode these images when they were produced by SVT-AV1(-PSY)

Other

  • The enable-libdovi & enable-libhdr10plus flags in build.sh have been updated to enable-dovi & enable-hdr10plus. The old flags will still work, but are no longer documented & will be considered deprecated from this point forward.
  • We have a website now! Come check us out at svt-av1-psy.com!

Support Us

As SVT-AV1-PSY's codebase has become more complex and the encoder's capabilities have increased dramatically, our efforts have scaled in kind. We have poured hours into coding, testing, distributing, and supporting this piece of open-source software entirely for free, and our work isn't stopping any time soon.

If you appreciate the work that we do and you'd like to support us, we are always excited to see code contributions from outside of the core development team. Otherwise, you can support us monetarily via the links below.

Gianni Rosato: Donate
Julio Barba: Coming Soon
BlueSwordM: Coming Soon
Clybius: Coming Soon

Any support you can offer goes a long way, and we sincerely appreciate it. ♥️
