[edit] 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.
libjxl's Butteraugli is used.
[edit] Requirements
- AviSynth+ >=3.6 required in order to use this filter.
- [x86] AviSynth+
- [x64] AviSynth+
- Supported color formats: Planar RGB (8-32bit)
[edit] Syntax and Parameters
- Butteraugli (clip reference, clip distorted, bool "distmap", float "intensity_target", bool "linput")
- reference =
- distorted =
- Clips that are use for estimating the psychovisual similarity. They must be in planar RGB format (8-32bit).
- reference =
- bool distmap = false
- Whether to return heatmap instead of distorted clip
- bool distmap = false
- float intensity_target = 80.0
- Viewing conditions screen nits
- float intensity_target = 80.0
- bool linput = false
- True: The input clips must have linear transfer functions.
- False: The input clips are assumed in sRGB color space and internal conversion to linear transfer function is done.
- bool linput = false
- The psychovisual similarity of the clips will be stored as frame property '_FrameButteraugli' in the output clip. Larger values indicate to bigger difference.
[edit] Examples
# Return the difference between the clips with displayed all frame properties alongside with '_FrameButteraugli' Butteraugli(clip1, clip2, distmap=true, linput=false) propShow()
# Return clip2 with displayed the value of the frame property '_FrameButteraugli'.
Butteraugli(clip1, clip2, linput=false)
ScriptClip("""Subtitle(String(propGetFloat("_FrameButteraugli")))""")
