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.


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)
