Description

Creates mask to process only edges; rainbows are removed by hitting chroma planes with two passes of FluxSmooth (hence "Double-Flux-Mask").

Requirements

• AviSynth 2.5.8 or greater
• Supported color formats: YV12

Required Plugins

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

• Deen (beta 2)
• FluxSmooth
• MaskTools2
• MSharpen

Syntax and Parameters

DFMDeRainbow (clip org, int "maskthresh", bool "mask", bool "interlaced")

clip  org =

Input clip.

int  maskthresh = 10

This is MSharpen's threshold value.

Lower values will increase the area in which the blurred chroma is allowed to come through, which catches more edges but may cause desaturation and/or chroma bleeding.

Set this as high as you can while still catching all the edges that need to be derainbowed.

bool  mask = false

When true, this displays the mask instead of the image. Use this to find the optimal value of maskthresh.

bool  interlaced = false

False means the input clip is progressive; with true it's interlaced. Interlaced content is processed by using SeparateFields in the beginning and Weave at the end.

Note: this parameter was added as an after-thought, it's not technically correct so use with caution and only as a last resort.

Examples

DFMDeRainbow with default settings:

AviSource("Blah.avi")
DFMDeRainbow(maskthresh=10, mask=false, interlaced=false)
