[edit] Description

Noise generator that tries to simulate the behavior of silver grain on film.

[edit] Requirements

  • AviSynth 2.5.8 or later
  • Supported color formats: YV12
  • Progressive input only


[edit] Required Plugins


[edit] Syntax and Parameters

GrainFactory3 (clip clp, int "g1str", int "g2str", int "g3str", int "g1shrp", int "g2shrp", int "g3shrp", float "g1size", float "g2size", float "g3size", int "g1tex", int "g2tex", int "g3tex", int "temp_avg", int "ontop_grain", int "th1", int "th2", int "th3", int "th4")


Input:
clip  clp =
Input clip.


Strength of grain:
int  g1str = 13
Strength of grain / for dark areas.
Range: 0 - ???
int  g2str = 15
Strength of grain / for midtone areas.
Range: 0 - ???
int  g3str = 25
Strength of grain / for bright areas.
Range: 0 - ???


Sharpness of grain:
int  g1shrp = 60
Sharpness of grain / for dark areas (NO EFFECT when g1size=1.0 !!)
Range: 0 - 100
int  g2shrp = 66
Sharpness of grain / for midtone areas (NO EFFECT when g2size=1.0 !!)
Range: 0 - 100
int  g3shrp = 80
Sharpness of grain / for bright areas (NO EFFECT when g3size=1.0 !!)
Range: 0 - 100


Size of grain:
float  g1size = 1.50
Size of grain / for dark areas.
Range: 0.5 - 4.0
float  g2size = 1.20
Size of grain / for mid-tone areas.
Range: 0.5 - 4.0
float  g3size = 0.90
Size of grain / for bright areas
Range: 0.5 - 4.0


Texture:
int  g1tex = 0
Strength of "material texture" appearance.
Range: 0 - 100
int  g2tex = 0
(In fact: 'bump' effect)
Range: 0 - 100
int  g3tex = 0
For dark / midtone / bright grain.
Range: 0 - 100


Temporal averaging:
int  temp_avg = 0
Percentage of noise's temporal averaging.
Range: 0 - 100


Mixing zone:
int  th1 = 24
Start of dark->midtone mixing zone.
int  th2 = 56
End of dark->midtone mixing zone.
int  th3 = 128
Start of midtone->bright mixing zone.
int  th4 = 160
End of midtone->bright mixing zone


On top grain:
int  ontop_grain = 0
additional grain to put on top of previously generated grain.
Range:0 - ???


[edit] Examples 

AviSource("Blah.avi")
Grainfactory3(5,7,10)
