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. It's recommended to use higher values with c2.

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
