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")))""")
