Description

Fast luma-adaptive grain generator for AviSynth+.

Requirements

• [x86/x64]: AviSynth+
• Progressive input only

Required Plugins

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

• neo_f3kdb
• MaskTools2
• RgTools

Syntax and Parameters

f3kgrainPlus (clip input, int "luma", int "chroma", int "mode", int "temp", int "adapt", float "sigma")

clip  input =

Input clip; all 8-16 bit Y/YUV colorspaces are supported, except YV411.

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.

Examples

f3kgrainPlus with default settings:

AviSource("Blah.avi")
f3kgrainPlus(luma=64, chroma=64, mode=1, temp=50, adapt=64, sigma=1.0)
