Another 8/16-bit luma adaptive grain generator.


Required Plugins

Latest version of the following plugins are recommended unless stated otherwise.

Syntax and Parameters

f3kgrain (clip input, int "luma", int "chroma", int "mode", int "temp", int "adapt", float "sigma", bool "lsb")

clip  input =
Input clip.

int  luma = 64
Luma grain strength; 0 disables processing, 4096 is the maximum value (heavy grain!).

int  chroma = 64
Chroma grain strength; 0 disables processing, 4096 is the maximum value (heavy and colorful grain!).

int  mode = 1
random_algo_grain mode:
  • 0 - old algorithm,
  • 1 - uniform distribution,
  • 2 - Gaussian(normal) distribution.

int  temp = 50
Temporal stabilization for grain (the higher, the more calm).
Range: 0 to 100
  • 0 = nervous
  • 50 = default (half and half)
  • 100 = static

int  adapt = 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.

float  sigma = 1.0
Standard deviation of Gaussian distribution mode.

bool  lsb =
Is the input clip normal 8-bit or stacked 16-bit? If lsb=true 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.


f3kgrain with default settings:

f3kgrain(luma=64, chroma=64,mode=1, temp=50, adapt=64, sigma=1.0)
