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:

- AviSynth 2.5.8 or later
- Supported color formats: YUY2, YV12



Syntax and Parameters

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


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


c1 int = 12
c2 int = 112
Range: 0 - 256
c1 and c2 are both 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.


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


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


ylimit bool = true


climit bool = true
