## Version 2.5: SSIMULACRA2&XPSNR-based
The requirements are Vapoursynth, LSMASHSource, Av1an, vszip and a few python library libraries. Optionally: ffmpeg built with XPSNR support, turbo-metrics.
Refined 2.0 with the following additions & changes:
- Proper argument parsing, more control over the script
- Separated the fast encode, metric calculation and zone creation into three independant, callable stages
- Replaced the deprecated `vapoursynth-ssimulacra2` by `vszip`
- Added `turbo-metrics` for GPU-accelerated metrics measurement (Nvidia only)
- Added XPSNR metric and a few zones calculation methods
- Taking advantage of SVT-AV1-PSY quarter-step CRF feature for more granular control
- Possibility to use a more aggressive boosting curve
- And a few other smaller changes...
_Many thanks to R1chterScale, Yiss and Kosaka for iterating on auto-boost and making these amazing contributions!_
