FixChromaBleedingMod

Revision as of 11:26, 17 December 2015

Description

A script to reduce color bleeding, over-saturation, and color shifting mainly in red and blue areas. This script is based on FixChromaBleeding.

Requirements

• AviSynth 2.5.8 or greater
• Progressive input only or Fields
• Supported color formats: YUY2, YV12, YV411

Required Plugins and Scripts

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

• ChromaShift
• ChromaShiftSP
• MaskTools2

Syntax and Parameters

FixChromaBleedingMod (clip input, int "cxShift", int "cyShift", float "thr", float "strength", bool "f", float "opacity", bool "n", bool "xysh", bool "Bic")

clip   =

Input clip.

int  cxShift = -4

int  cyShift = -4

Horizontal and vertical chroma shift; vertical shift is ignored when xysh=false (default).

• When xysh=false, positive values shift chroma to the right, negative values shift to left.
• When xysh=true, positive values shift chroma to the left/up, negative values shift right/down.

float  thr = 4.0

Masking threshold, higher values treat more areas as color bleed.

float  strength = 0.8

Saturation strength in clip to be merged with the original chroma. Values below 1.0 reduce the saturation, a value of 1.0 leaves the saturation intact.

bool  f = true

Set to true to enable fast processing on the mask clip (default).

float  opacity = 1.0

Opacity strength when blending the original chroma with the corrected one. Range is from 0.0 to 1.0.

bool  n = false

Set to true to blur the mask clip. This parameter is ignored when f=true, when f=false the mask clip is always blurred.

bool  xysh = false

Set to true to shift chroma with ChromaShiftSP which also allows vertical shifting.

bool  Bic = false

Set to true to scale the mask with BicubicResize instead of BilinearResize. This parameter is ignored when f=false.

Examples

FixChromaBleedingMod with default settings:

AviSource("Blah.avi")
FixChromaBleedingMod(cxShift=-4, cyShift=-4, thr=4.0, strength=0.8, f=true, opacity=1.0, n=false, xysh=flase, Bic=false)
