Description

Noise reduction filter which reduces cross-color (rainbows) and cross-luminance (dot crawl) artifacts. It works by temporally blending only static parts of a frame.

Requirements


Syntax and Parameters

cc (clip, int "y1", int "y2", int "c1", int "c2", bool "interlaced", float "yc", bool "ylimit", bool "climit")


clip   =
Input clip.


int  y1 = 8
int  y2 = 8
Range: 0 - 256
Luma thresholds that control how much cross-luminance is reduced. Higher values increase strength.


int  c1 = 12
int  c2 = 112
Range: 0 - 256
Chroma thresholds that control how much cross-color is reduced. Higher values increase strength.
The value of c1 should always be less than c2. For c2 it's recommended to use higher values.


bool  interlaced = true
When set to false, input will be treated as progressive. This only applies to YV12.


float  yc = 2.0
Value that represents how much cross-luminance the chrominance signal has introduced.


bool  ylimit = true
Luma limiter; saturates the result of the luminance calculation.
If ylimit=true, it will saturate the result of the luminance calculation using the maximum and minimum values ±1 in the range of 4 pixels wide by 1 pixel high of the original image.


bool  climit = true
Chroma limiter; saturates the result of the chrominance calculation.
If climit=true, the result of the color calculation will be saturated using the maximum and minimum values of the original image within a range of 7 pixels wide by 1 pixel high ±1.


Examples

cc with default values: 

AviSource("Blah.avi")
cc(y1=8, y2=8, c1=12, c2=112, interlaced=true, yc=2.0, ylimit=true, climit=true)
