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 later

- Supported color formats: YV12

Required Filters:

• MaskTools2 2.0a48+
• SmoothUV

Syntax and Parameters

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

radius int = 3

Range: 0 - 7

The smoothing radius of SmoothUV.

lthresh int = 0

hthresh int = 220

Range: 0 - 255

The low and high smoothing threshold.

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 thresh 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.
