[edit] Description

This is a derainbowing script which works with SSIQ. The basic problem with SSIQ is that it can alter the color on the entire picture, which is a very bad thing. All we want to do is remove rainbows, while leaving everything else alone. To accomplish this, SSIQ is applied (at full strength) to the entire frame. An edge mask is created from the original video. And finally, using Overlay it will blend ONLY the de-rainbowed edges onto the original video.

Note: SmartSSIQ with default settings can cause slight discoloration on derainbowed areas.

[edit] Requirements

  • AviSynth 2.5.8 or greater
  • Supported color formats: YV12

[edit] Required Plugins

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


[edit] Syntax and Parameters

SmartSSIQ (clip input, int "strength", bool "interlaced")


clip  input =
Input clip.


int  strength = 200
Processing strength; this value ultimately controls the opacity* in overlay.
Range: 0 to 255


*opacity = strength/255.0


bool  interlaced = false
False means the input clip is progressive; with true it's interlaced.
Note: this parameter was added as an after-thought, so use it with caution and only as a last resort.


[edit] Examples

SmartSSIQ with default settings:

AviSource("Blah.avi")
SmartSSIQ(strength=200, interlaced=false)
