Description

Butteraugli estimating filter for the psychovisual similarity of two images.

A quality metric for lossy image and video compression.

This is a port of the VapourSynth plugin butteraugli.

Google's Butteraugli is used.

Requirements

  • AviSynth+ >=3.6 required in order to use this filter.
  • [x86] AviSynth+
  • [x64] AviSynth+
  • Supported color formats: RGBP8


Syntax and Parameters

Butteraugli (clip clip1, clip clip2, bool "heatmap")


clip   =
clip   =
Clips that are use for estimating the psychovisual similarity. They must be in RGB 8-bit planar format.


bool  heatmap = true
True: A heatmap is returned containing differences between two input clips.
False: Returns clip2.


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


Examples

# Return the difference between the clips with displayed all frame properties alongside with '_FrameButteraugli'
Butteraugli(clip1, clip2, heatmap=true)
propShow()


# Return clip2 with displayed the value of the frame property '_FrameButteraugli'.
Butteraugli(clip1, clip2, heatmap=false)
ScriptClip("""Subtitle(String(propGetFloat("_FrameButteraugli")))""")
