EdgeBlur

Blurs detected edges within the matte specified in the matte channel.

Inputs and Controls

Connection Type	Connection Name	Function
Input	unnamed	The image sequence to blur.
mask	An optional image to use as a mask. By default, the blur effect 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.

mask

An optional image to use as a mask. By default, the blur effect 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
EdgeBlur Tab
channels	channels	all	The blur effect is only applied to these channels. If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels.
matte input	N/A	enabled	Enables the associated mask channel to the right. Disabling this checkbox is the same as setting the channel to none.
matte input	control channel	rgba.alpha	Sets the channel containing the alpha used to detect the edges.
size	size	3	Sets the size of the blur applied to the detected edges.
filter	filter	gaussian	Select the filter algorithm to use: • box • triangle • quadratic • gaussian NOTE: Box is the fastest to render, whereas Gaussian blur is the smoothest.
quality	quality	15	Sets the quality of the applied filter. Lower values produce faster renders at the expense of smoothness, and vice-versa. NOTE: The image is scaled down so the blur filter is no larger than this number, and then scaled up using linear interpolation after filtering.
crop to format	crop	enabled	When enabled, if the bounding box equal to or less than the format, don't enlarge it past the format. This avoids creating oversized images that you don't use.
edge mult	edge_mult	2	Controls the sharpness of the edge blur. Lower values produce sharper edges and vice versa.
tint	tint	1	Sets the multiplier for the rgb channels in the edge blur.
brightness	brightness	1	Sets the multiplier for all channels in the edge blur.
output	N/A	disabled	Enables the associated mask channel to the right. Disabling this checkbox is the same as setting the channel to none.
output	output	none	Sets the output channel for any blur applied.
mask	N/A	disabled	Enables the associated mask channel to the right. Disabling this checkbox is the same as setting the channel to none.
mask	maskChannelInput	none	The channel to use as a mask. By default, the blur 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 blur is limited to the non-white areas of the mask.
fringe	fringe	disabled	Blurs the edges of the mask.
mix	mix	1	Dissolves between the original image at 0 and the full blur effect at 1.
