Description

AddGrainC generates film like grain or other effects (like rain) by adding random noise to a video clip.
This noise may optionally be horizontally or vertically correlated to cause streaking.


Requirements:

- AviSynth 2.5.8 or later
- Microsoft Visual C++ 2012 Redistributable Package
- MMX or SSE2 capable cpu
- Progressive input only
- Supported color formats: YUY2, YV12, YV16, YV24, YV411, Y8


Syntax and Parameters

AddGrainC (float "var", float "uvar", float "hcorr", float "vcorr", int "seed", bool "constant", bool "sse2")


var float = 1.0
The standard deviation (strength) of the luma noise, 0 is disabled.


uvar float = 0.0
The standard deviation (strength) of the chroma noise, 0 is disabled.
uvar does nothing in RGB mode.


hcorr float = 0.0
vcorr float = 0.0
Horizontal and vertical correlation, which causes a nifty streaking effect.
Range: 0.0 - 1.0


seed int = -1
Specifies a repeatable grain sequence. Set to at least 0 to use.


constant bool = false
Specifies a constant grain pattern on every frame.


sse2 bool = true
Enable sse2 optimization if available. 1.5x faster than mmx.


Examples

AviSource("Blah.avi")
StaticNoiseC(var=1.0, uvar=0.0, hcorr=0.0, vcorr=0.0, seed=-1, constant=false, sse2=true)
