[edit] Description
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.
[edit] Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: RGB24, RGB32, YUY2, YV12
[edit] Syntax and Parameters
- NoiseGenerator (clip, bool "Gaussian", int "Amount", bool "LumaOnly")
- clip =
- Input clip
- clip =
- bool Gaussian = false
- If Gaussian parameter is false, a uniform noise is generated.
- bool Gaussian = false
- int Amount = 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.
- int Amount = 10
[edit] Examples
NoiseGenerator with default settings:
AviSource("Blah.avi") NoiseGenerator(Gaussian=false, Amount=10, LumaOnly=false)
