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
- Progressive input only
- Supported color formats: RGB24, RGB32, YUY2, YV12, YV16, YV24, YV411, Y8


- MMX or SSE2 capable cpu
- Microsoft Visual C++ 2012 Redistributable Package


Syntax and Parameters

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


float  var = 1.0
The standard deviation (strength) of the luma noise, 0.0 is disabled.


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


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


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


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


bool  sse2 = true
Enable SSE2 optimization if available. 1.5x faster than MMX.


Examples

AddGrainC with default values: 

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


Changelog 

Version      Date            Developer       Changes

1.7.1      2013/11/25      Firesledge       Added a 64-bit version. Compiled with MSVC 2012 (requires the 2012 runtime libraries) 
1.7.0      2012/08/16      Firesledge       Supports Y8, YV16, YV24 and YV411 colorspaces.
1.6.1      2011/10/29      LaTo INV.        Automatic switch to MMX if SSE2 is not supported by the CPU.
1.6.0      2011/10/28      LaTo INV.        Added SSE2 code (50% faster than MMX)
1.5.4      2011/10/27      Firesledge       Fixed bad pixels on the last line in YV12 mode when constant=true,
                                              fixed potential problems with frame width > 4096 pixels
                                              and fixed several other minor things.
1.5.3      2011/10/26      Firesledge       Fixed coloring and bluring in RGB24 mode.
1.5.2      2011/10/26      Firesledge       Removed the SSE2 requirement.
1.5.1      2010/05/13      Firesledge       The source code compiles on Visual C++ versions older than 2008.
1.5        2010/05/07      Foxyshadis       Limit the initial seed generation to fix memory issues.
1.4          2006/08/11      Foxyshadis      Constant replaces seed, seed repeatable.
1.3        2006/06/10      Foxyshadis       Crashfix, noisegen optimization.
1.2        2006/06/06      Foxyshadis       Supports YUY2, RGB. Fix cache mess.
1.1        2006/06/01      Foxyshadis       Chroma grain + constant seed.
1.0        2003/06/18      Tom Barry        Initial Release
