SmoothUV2

Revision as of 02:44, 24 May 2020

Description

SmoothUV2 is a spatial derainbow filter. This filter performs structure-preserving smoothing (blurring) on the U/V (chrominance or colour) information of the image, leaving Y (luminance) intact. It was created in an attempt to reduce the appearance of "rainbows" (cross-colour artifacts) near lines in some cel animation.

This version is a port of the VapourSynth version, changes to the original SmoothUV:

• Only SmoothUV() implemented
• "fields" parameter renamed to "interlaced"
• Additional colorspace support
• x64 bit version

Requirements

• [x86]: AviSynth+ or AviSynth 2.6
• [x64]: AviSynth+
• Supported color formats: YV12, YV16, YV24

Syntax and Parameters

SmoothUV (clip, int "radius", int "threshold", bool "interlaced")

clip   =

A clip to process. It must have constant format and it must be 8 bit YUV.

int  radius = 3

Radius. Must be between 1 and 7.

Larger values smooth more.

Default: 3

int  threshold = 270

Threshold. Must be between 0 and 450.

Larger values smooth more.

Default: 270

bool  interlaced =

Determine if the frame is interlaced.

Default: auto detect based on Is.FiledBased().

False is for progressive input, true is for interlaced input.

Examples

SmoothUV with default settings:

AviSource("Blah.avi")
SmoothUV(radius=3, threshold=270)
