Description

A quality metric for lossy image and video compression.

This is a port of the VapourSynth plugin butteraugli.

libjxl's Butteraugli is used.

Requirements:

• AviSynth+ 3.6 or later

• Microsoft VisualC++ Redistributable Package 2022 (can be downloaded from here)

Usage:

Butteraugli (clip reference, clip distorted, bool "distmap", float "intensity_target", bool "linput")

Parameters:

• reference, distorted
  Clips that are used for estimating the psychovisual similarity.
  They must be in RGB 8/16/32-bit planar format and must have same dimensions.

• distmap
  Whether to return heatmap instead of distorted clip
  Default: False.

• intensity_target
  Viewing conditions screen nits.
  Default: 80.0.

• linput
  True: The input clips must have linear transfer functions.
  False: The input clips are assumed in sRGB color space and internally converted to linear transfer.
  Default: False.

The psychovisual similarity of the clips will be stored as frame property '_FrameButteraugli' in the output clip. Larger values indicate to bigger difference.

Building:

Requirements:
    - Git
    - GCC C++17 compiler
    - CMake >= 3.16
