v2.2.1-B

Our first ever B release is here with SVT-AV1-PSY v2.2.1-B! 🕺

PSY Updates

Features

• New parameter --noise-norm-strength for controlling noise normalization. It is configurable with values 0 through 4, with a default value of 0. Noise normalization intelligently boosts higher frequency details in parts of the video where these details may otherwise be erased, helping preserve visual consistency in some scenarios.

Quality & Performance

• Tune 4 variance boost scaling is now a bit flatter
• Adjusted Tune 4 lambda weights
• Limited the maximum available transform size available to Tune 4 to 32x32
• Adjusted the default sharpness parameter used by Tune 4
• New custom Variance Boost curve for Tune 4
• Ported speedups for AVX2 hardware from aomenc

Documentation

• DLF 2 option is now properly reflected in the help menu

Bug Fixes

• Fixed a bug where on certain devices under specific circumstances, encoding extremely small images resulted in a floating point exception

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.
