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.
- clip =
- int y1 = 8
- int y2 = 8
- Range: 0 - 256
- int y1 = 8
- Luma thresholds that control how much cross-luminance is reduced. Higher values increase strength.
- int c1 = 12
- int c2 = 112
- Range: 0 - 256
- int c1 = 12
- 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
- bool interlaced = true
- When set to false, input will be treated as progressive. This only applies to YV12.
- float yc = 2.0
- float yc = 2.0
- Value that represents how much cross-luminance the chrominance signal has introduced.
- bool ylimit = true
- bool ylimit = true
- Luma limiter
- bool climit = true
- bool climit = true
- Chroma limiter
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)
Changelog
2004/05/22: - Optimize limiter - Add chroma limiter "climit"
2004/03/15: - Add limiter "ylimit" - Add parameter "yc"
2004/03/06: - Add parameter "interlace" - YV12 support - AviSynth 2.5 support
2003/12/17: - Add parameters y1,y2,c1,c2
2003/10/13: - Initial release
