NoiseGenerator

Revision as of 13:45, 29 December 2013

Another noise generator. This filter is based on NoiseGenerators by Ross Thomas and uses some of its codebase.

Unlike the original, this filter is now for AviSynth 2.5 and has different parameters.

- AviSynth 2.5.8 or later

- Supported color formats: YV12, YUY2, RGB24, RGB32

- Progressive input only

NoiseGenerator (clip, bool "Gaussian", int "Amount", bool "LumaOnly")

Gaussian bool = false

If Gaussian parameter is false, a uniform noise is generated.

Amount int = 10

Amount specifies how much noise should be added.

In RGB if noise is added to black picture, it should be >0, if the picture is almost white, it should be <0.

LumaOnly bool = false

If LumaOnly parameter is true, only luma channel is affected in YUY2 and YV12, and in RGB mode only lightness is changed (no color change).

AviSource("Blah.avi")
NoiseGenerator(Gaussian=false, Amount=10, LumaOnly=false)
