Sharpen compositing node

Increases the size of the areas over which it performs the sharpen (in pixels). Larger values will enhance larger features.

The units that the Size parameter is expressed in, either pixels or UV coords.

Intensity of the sharpen effect.

If on, image noise is not sharpened. Noise is any edge that has a smaller magnitude than the Noise Suppress value. This produces clearer images.

Image variances less than the suppress value are not sharpened (as if the effect was zero). If a blend region is used, variances just above the suppress cutoff are sharpened somewhat, depending on their position within the blend region.

           |  No Sharpening |  Diminished Sharpening  |  Full Sharpening
effect:    |       0%       |    25%     50%     75%  |       100%  ---->
           |                |      suppress blend     |
variance:  0           (Suppress)             (Suppress + Blend)

Determines how noise in the Suppress Blend range is sharpened:

The size of the blend region between full sharpening and no sharpening of the variances just above the noise threshold. This prevents “patches” of sharp areas in the image by blending the patches in.

Sharpens all the edges, while removing non-edge components.

If no mask is present, this blends the output with the input by a constant amount (0 = all input, 1 = all output).

If a mask is present, this amount multiplies the mask.

Selects the mask plane to use as a mask from the mask input. The mask can be selected from:

A mask can be a component of a plane or an entire plane. If a vector plane is supplied as a mask, its components are multiplied by the images' components.

Scalar Mask ('A', 'C.r')

C.r = I.r * M
C.g = I.g * M
C.b = I.b * M

C.r = I.r * M.r
C.g = I.g * M.g
C.b = I.b * M.b

If the mask image is a different resolution than the output image, turning on this parameter will scale the mask to the output image’s resolution.

If this node is changing constantly, and the mask is not, it is somewhat faster to put a Scale COP down to do the resize for the mask image. Otherwise, the scale will occur every time this node cooks.

Inverts the mask so that all fully 'masked' portions become unmasked. This saves you from inserting an Invert COP after the node with the mask.

Specifies the scope for both the RGB components of Color, Alpha, and other planes. The (C)RGBA mask only affects Color components and Alpha. 'C' will toggle all the RGB components.

For planes other than Color and Alpha, the plane name (plus component, if applicable) should be specified in the string field. The pulldown menu can be used to select planes or components present in this node.

A plane is specified by its name. A component is specified by both its plane and component name. The '*' wildcard may be used to scope all extra planes. Any number of planes or components can be specified, separated by spaces.

Examples:

P
N.x N.y
P N Pz

Allows scoping of specific frames in the frame range. This is in addition to the plane scope (so a plane at a certain frame must be both plane scoped and frame scoped to be modified).

For Inside/Outside range, this parameter specifies the subrange of the sequence to scope (or unscope). This can be edited in Timeline viewer mode ( Ctrl + 2 in viewer).

For Inside/Outside Range, this parameter specifies certain number of frames before and after to slowly ramp up to scoped. The operation will be blended with its input to 'ease in' or 'ease out' the scoping effect over a number of frames. This can be edited in Timeline viewer mode ( Ctrl + 2 in viewer).

For unscoped frames, this sets the blend factor between the input and modified images. Normally this is zero (use the input image). By setting this to a non-zero value, you can make unscoped frames be 'slightly' unscoped. The value can vary between 0 (unscoped) and 1 (scoped).

The frame list for 'Specific Frames'. Frame numbers should be separated by spaces.

If the sequence range changes, enabling this parameter will adjust the subrange and frame dropoff lengths to fit the new range.
