== Description ==
Another 8/16-bit luma adaptive grain generator.<br/>
<br>
== Requirements ==
* [http://forum.doom9.org/showthread.php?t=168764 AviSynth 2.6.0 Alpha5] 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: [[YV12]], [[YV16]], [[YV24]]

==== Required Plugins ====
Latest version of the following plugins are recommended unless stated otherwise.<br>
*[//forum.doom9.org/showpost.php?p=1386559&postcount=3 Dither]
*[//forum.doom9.org/showthread.php?t=161411 f3kdb v1.5.1] (v2.0pre2 is still considered experimental)
*[[MaskTools2]]
*<strike>[[RemoveGrain v1.0b/RemoveGrain|RemoveGrain]] - part of the [[RemoveGrain v1.0b]] package.</strike>
*[[RgTools]] - recommended drop-in replacement for RemoveGrain!

:{{Template:FuncDef|f3kgrain (clip input, int "luma", int "chroma", int "mode", int "temp", int "adapt", float "sigma", bool "lsb")}}
<br>
::{{Par2|input|clip| }}
:::Input clip.
<br>
::{{Par2|luma|int|64}}
:::Luma grain strength; 0 disables processing, 4096 is the maximum value (heavy grain!).
<br>
::{{Par2|chroma|int|64}}
:::Chroma grain strength; 0 disables processing, 4096 is the maximum value (heavy and colorful grain!).
<br>
::{{Par2|mode|int|1}}
:::<tt>random_algo_grain</tt> mode: 
::::*0 - old algorithm, 
::::*1 - uniform distribution, 
::::*2 - Gaussian(normal) distribution. 
<br>
::{{Par2|temp|int|50}}
:::Temporal stabilization for grain (the higher, the more calm).
:::Range: 0 to 100

::::*0 = nervous
::::*50 = default (half and half)
::::*100 = static

<br>
::{{Par2|adapt|int|64}}
:::Brightness threshold for adaptive grain mask. 
:::Range: -1 to 255

::::*-1 = off
::::*0 = input
::::*64 = default
::::*255 = invert

:::The higher, the less grain in dark areas & the more grain in bright areas.
<br>
::{{Par2|sigma|float|1.0}}
:::Standard deviation of Gaussian distribution mode.
<br>
::{{Par2|lsb|bool| }}
:::Is the input clip normal 8-bit or [[Stack16|stacked 16-bit]]? If <tt>{{Template:FuncDef|lsb}}=true</tt> output clip will be stacked 16-bit.
:::By default the input clip's width is divided by the height, if is greater than 1.2 then it's set to false otherwise is set to true.

== Examples ==
f3kgrain with default settings:
 [[AviSource]]("Blah.avi")
 f3kgrain(luma=64, chroma=64,mode=1, temp=50, adapt=64, sigma=1.0)
