Some big changes have been introduced in SVT-AV1-PSY, courtesy of Clybius, the author of aom-av1-lavish! Here is the changelog:

Feature Additions

  • Tune 3 A new tune based on Tune 2 (SSIM) called SSIM with Subjective Quality Tuning. Generally harms metric performance in exchange for better visual fidelity.
  • --sharpness A parameter for modifying loopfilter deblock sharpness and rate distortion to improve visual fidelity. The default is 0 (no sharpness).

Modified Defaults

  • Default 10-bit color depth. Might still produce 8-bit video when given an 8-bit input.
  • Disable film grain denoising by default, as it often harms visual fidelity.
  • Default to Tune 2 instead of Tune 1, as it reliably outperforms Tune 1 on most metrics.
  • Enable quantization matrices by default.
  • Set minimum QM level to 0 by default.

That's all, folks! Keep an eye on the master branch for more changes in the future!
