Description

rainbow_smooth is a small spatial derainbowing function. It uses SmoothUV to smooth out chroma and edge masking to reduce the colour bleeding.

Requirements

• AviSynth 2.5.8 or greater
• Progressive input only
• Supported color formats: YV12

Required Plugins

Latest versions of the following filters are recommended unless stated otherwise.

• MaskTools2
• SmoothUV

Syntax and Parameters

rainbow_smooth (clip orig, int "radius", int "lthresh", int "hthresh")

clip  orig =

Input clip.

int  radius = 3

The smoothing radius of SmoothUV.

Range: 1 to 7

int  lthresh = 0

int  hthresh = 220

The low and high smoothing thresholds of SmoothUV; use smaller values for safer processing.

Masking is only used for hthresh, so if you set lthresh greater than hthresh, lthresh will be the overall threshold and no masking will be used (fastest).

If you set lthresh to 0, you disable the basic chroma smoothing and use only the chroma-smoothing on edges.

Range: 0 to 255

Examples

rainbow_smooth with default settings:

AviSource("Blah.avi")
rainbow_smooth(radius=3, lthresh=0, hthresh=220)
