== Description ==
: This filter is a Chroma Stabilizer for analog sources.
:It's a temporal filter and it's very effective against two chroma artifacts: Stationary rainbows and huge analog chroma activity.

:Cnr2 was inspired by the VirtualDub filter [http://web.archive.org/web/20041205081740/http://freevcr.ifrance.com/freevcr/virtualdub/cnr-en.html Chroma Noise Reduction 1.1] by Gilles Mouchard.
 
== Requirements: ==
:- AviSynth 2.5.8 or later
:- [[FAQ_different_types_content#How_do_I_recognize_progressive.2C_interlaced.2C_telecined.2C_hybrid_and_blended_content.3F|Progressive]] input only
:- Supported color formats: [[YUY2]], [[YV12]]
 
== [[Script variables|Syntax and Parameters]] ==

::{{Par2|mode|string| "oxx"}}
::::mode of each components, "YUV":
:::::* o : wide
:::::* x : narrow; this mode is more sensible to variations, and less effective. 
 
::{{Par2|scdthr|float|10.0}}
::::Scene change detection threshold (as percentage of maximum possible change):
:::::If {{Template:FuncDef|sceneChroma}} is set to true, then it is the maximum possible change including both luma and chroma.
:::::If {{Template:FuncDef|sceneChroma}} is set to false then it is the maximum possible change considering luma only (luma only is more reliable).
::::Lower it to make scene change detection more sensible. If a scene change is detected, Cnr2 will reset the filtering for the new scene.

::{{Par2|vm|int|255}}
:::Range: 0 to 255
::::The ''n'' values are the movement sensibility; higher values will denoise more, but could produce ghosting artifacts.

::::The ''m'' values are the maximum effectiveness of the denoiser; lower them to reduce the denoising effect.
 
::{{Par2|log|bool|false}}
::::Log the scene change stats (output them using OutputDebugString). You can use [http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx DebugView] to see it.
::::It will simply list the detected change, the maximum allowable change for the current {{Template:FuncDef|scdthr}} setting, and the ratio (at 1.0 or greater a scene change has occurred).
 
::{{Par2|sceneChroma|bool|false}}
::::Sets whether or not both chroma and luma are considered on scene change detection (true), or only luma (false).
::::Luma only detection tends to be more reliable.
 
== Examples ==
