S_AdvancedDefocusGenerates a defocused version of the source clip using a 'circle of confusion' convolution. This effect is often preferable to a gaussian blur for simulating a real defocused camera lens, because bright spots can be defocused into clean shapes instead of being smoothed away. The iris shape can be controlled using Points, Pointiness and Rotate, and the Use Gamma and Boost Highlights parameters can adjust the relative brightness of the blurred highlights. Use the params in the Lens Vignette group to simulate optical vignetting and matte box artifacts.In the Sapphire Blur+Sharpen category. Inputs:

- Optical Vignette:
Default:
0,
Range:
-1 to 1.
Simulates optical vignetting, which crops the defocused highlights into a pointed ellipse shape and darkens the output. The effect is stronger near the edges of the frame. Larger values increase the amount of cropping, and cause the effect to extend more toward the center of the frame. Positive values crop the inner edges of the highlights, and negative values crop the outside edges.
- Vignette Size:
Default:
1,
Range:
1 or greater.
Controls the relative size of the vignette crop circle. Larger values will reduce the intensity of the effect, as well as the curvature of the cropped edge.
- Matte Box Left:
Default:
0,
Range:
0 to 4.
Crops the inner edge of defocused highlights on the left side of the frame. Larger values increase the amount of cropping and extend it farther across the frame.
- Matte Box Right:
Default:
0,
Range:
0 to 4.
Crops the inner edge of defocused highlights on the right side of the frame. Larger values increase the amount of cropping and extend it farther across the frame.

- Grain Seed:
Default:
0.123,
Range:
0 or greater.

The amount to increase the luma of the highlights in the source clip. Increase this parameter to blow out the highlights without affecting the darks or mid-tones.
- Hilight Threshold:
Default:
0.9,
Range:
0 or greater.
The minimum luma value for highlights. Pixels brighter than this will be brightened according to the Boost Highlights parameter.
- Chromatic Aberration:
Default:
0,
Range:
any.
Adds some chromatic aberration around the edges of the image; red and blue wavelengths of light refract differently in real lenses, producing fringes of color where the rays strike the lens at oblique angles.

- Gauss Blur:
Default:
0,
Range:
0 or greater.
If positive, a gaussian blur is also applied which smooths out the edges of the shapes. This might also darken the highlights because Gamma is not considered in the gaussian blur.
- Mix With Source:
Default:
0,
Range:
0 to 1.
Interpolates between the defocused result and the original source. Set this to 1 for the original source.
- Edge Mode:

Check-box, Default:
off.
If enabled, defocus the alpha channel as well as the color channels. Otherwise, only defocus the color channels, leaving alpha unchanged.
- Mask Use:
Popup menu, Default: Luma
.
Determines how the Mask input channels are used to make a monochrome mask.- Luma:
the luminance of the RGB channels is used.
- Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.

- Luma:
the luminance of the RGB channels is used.
- Blur Mask:
Default:

- Invert Mask:
Check-box, Default:
off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.
