Inputs and Controls

Connection Type	Connection Name	Function
Input	unnamed	The image sequence to degrain.
	mask	An optional image to use as a mask. By default, the grain reduction is limited to the non-black areas of the mask. At first, the mask input appears as triangle on the right side of the node, but when you drag it, it turns into an arrow labeled mask. If you cannot see the mask input, ensure that the mask control is disabled or set to none.

Control (UI)	Knob (Scripting)	Default Value	Function
DegrainSimple Tab
channels	channels	all	The channels to degrain. If you set this to something other than all, rgba, or rgb, the R blur, G blur, and B blur sliders below affect the first three channels in the selected layer.
R blur	rVal	2	The amount of grain to remove from the red channel.
G blur	gVal	2	The amount of grain to remove from the green channel.
B blur	bVal	5	The amount of grain to remove from the blue channel, which often is where most grain occurs.
mask	N/A	disabled	Enable the associated mask channel to the right. Disabling this checkbox is the same as setting the channel to none.
	maskChannelInput	none	The channel to use as a mask. By default, the grain reduction is limited to the non-black areas of this channel.
inject	inject	disabled	Copies the mask input to the predefined mask.a channel. Injecting the mask allows you to use the same mask further downstream.
invert	invert_mask	disabled	Inverts the use of the mask channel so that the grain reduction is limited to the non-white areas of the mask.
fringe	fringe	disabled	When enabled, only apply the effect to the edge of the mask. When disabled, the effect is applied to the entire mask.
mix	mix	1	Dissolves between the original image at 0 and the full grain reduction at 1.
