WhiteNoise

Adds various types of seemingly random noise to the input image, all based on White noise.

Inputs and Controls

Connection Type	Connection Name	Function
Input	src	The image sequence to which white noise is added.
	mask	An optional image to use as a mask. By default, the effects are applied according to the value in the alpha channel of the mask.

Control (UI)	Knob (Scripting)	Default Value	Function
Enabled	Enabled	ticked	If unchecked, this node will be omitted from the compiled image processing graph. Any incoming connections will be forwarded to the first output port, if any.
Label	Label	N/A	An optional label to display on the node.
Parameters
Reset parameters to default value using the reset icon:
Resolution	Resolution	1920 x 1080	The resolution of the output image, if there is no input node. If there is an input node the resolution will be taken from that.
Mode	Mode	Smooth	Sets the activation function used by the pixels. Choose between: • Smooth • Constant • Step
Colour	Colour	1.000	Sets maximum values for each colour channel.
Speed	Speed	1.000	Sets the speed at which a pixel completes an activation cycle. A value of 1.0 will typically equate to a cycle taking roughly 6 seconds.
Density	Density	1.000	Sets the percentage of time a pixel spends within the activation function. Lower values will create larger areas of black at any given time.
Randomise red	RandomiseRed	unticked	If enabled, randomises the red channel of a pixel between 0.0 and the red channel in Colour.
Randomise green	RandomiseGreen	unticked	If enabled, randomise the green channel of a pixel between 0.0 and the green channel in Colour.
Randomise blue	RandomiseBlue	unticked	If enabled, randomise the blue channel of a pixel between 0.0 and the blue channel in Colour.
Randomise alpha	RandomiseAlpha	unticked	If enabled, randomise the alpha channel of a pixel between 0.0 and the alpha channel in Colour.
Constant alpha	ConstantAlpha	ticked	If enabled, forces the alpha channel to be a constant 1.0.
