Description
Another 8/16-bit luma adaptive grain generator.
Requirements
- AviSynth 2.6.0 Alpha5 or later
- Progressive input only
- Supported color formats: YV12, YV16, YV24
Required Plugins
- Dither v1.26.3 or later
- f3kdb v1.5.1 (v2.0pre2 is still considered experimental)
- MaskTools2 2.0a48+
- RemoveGrain - part of the RemoveGrain v1.0b package.
Syntax and Parameters
- f3kgrain (clip input, int "luma", int "chroma", int "mode", int "temp", int "adapt", float "sigma", bool "lsb")
- clip input =
- Input clip.
- clip input =
- int luma = 64
- Luma grain strength; 0 disables processing, 4096 is the maximum value (heavy grain!).
- int luma = 64
- int chroma = 64
- Chroma grain strength; 0 disables processing, 4096 is the maximum value (heavy and colorful grain!).
- int chroma = 64
- int mode = 1
- random_algo_grain mode:
- 0 - old algorithm,
- 1 - uniform distribution,
- 2 - Gaussian(normal) distribution.
- random_algo_grain mode:
- int mode = 1
- int temp = 50
- Temporal stabilization for grain (the higher, the more calm).
- Range: 0 to 100
- int temp = 50
- 0 = nervous
- 50 = default (half and half)
- 100 = static
- int adapt = 64
- Brightness threshold for adaptive grain mask.
- Range: -1 to 255
- int adapt = 64
- -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.
- float sigma = 1.0
- 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.
- bool lsb =
Examples
f3kgrain with default settings:
AviSource("Blah.avi") f3kgrain(luma=64, chroma=64,mode=1, temp=50, adapt=64, sigma=1.0)
