Description

Another noise generator for AviSynth.

Requirements:

- AviSynth 2.5.8 or later

- Supported color formats: YV12

- Progressive input only

Syntax and Parameters

gnoise (clip, float "sigma", int "seed", bool "color", bool "temporal", bool "info")

sigma float = 10.0

Controls the amount of noise. Set at 0.0 and noise will be disabled. As usual higher values increase noise.

seed int = 96

Specifies a repeatable grain sequence. Each value will produce a unique pattern.

color bool = false

If true, noise will be added to the chroma (U/V) also.

temporal bool = false

False produces static noise, true gives dynamic noise.

info bool = false

If set to true, it will display a graph. This parameter is undocumented so the true purpose of the graph is unknown.

Do not use! It is very slow.

Examples

AviSource("Blah.avi")
gnoise(sigma=2, seed=96, color=false, temporal=false, info=false)
