Release v2.1.0-A · gianni-rosato/svt-av1-psy

Introducing SVT-AV1-PSY v2.1.0-A

Features

  • New parameter --max-32-tx-size, which restricts block transform sizes to a maximum of 32x32 pixels. This can be useful in very specific scenarios for improving overall efficiency
  • Added support for HDR10+ JSON files via a new --hdr10plus-json parameter (thanks @quietvoid!). In order to build a binary with support for HDR10+, see our PSY Development page.
  • New parameter --adaptive-film-grain, which helps remedy perceptually harmful grain patterns caused by extracting grain from blocks that are too large for a given video resolution. This parameter is enabled by default

Quality & Performance

  • Disabled SSIM-cost transform decisions while keeping SSIM-cost mode decisions, generally improving Tune 3's efficiency & consistency
  • Additional NEON optimizations for ARM platforms, providing a speed increase

Documentation

  • All of the features present in this release have been documented, so associated documentation has been updated accordingly
  • Build documentation updated to reflect the HDR10+ build option

Bug Fixes

  • Disabled quantization matrices for presets 5 and higher due to a visual consistency bug (#56)
