Sapphire Plug-ins for AVX2: ZGlow

S_ZGlow

Glows areas of the source clip with varying widths depending on the depth values from a ZBuffer input. Separates the input into a number of layers and applies different amounts of glow depending on Width Near, Width Far, Brightness Near, and Brightness Far parameters.

In the Sapphire Lighting category.


Inputs:

Source: The current track. The clip to be processed.

Z Buffer: Selectable. The input clip containing depth values for each Source pixel. These values should be in the range of black to white, and it is best if not anti-aliased. Normally black corresponds to the farthest objects and white to the nearest, though this can be adjusted using Z Buffer parameter.

Background: Optional. The clip to combine the zs with. If no background is given, the Source is also used as the Background.

Parameters:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Brightness: Default: 2, Range: 0 or greater.
Scales the brightness of all the glows.

Color: Default rgb: [1 1 1].
Scales the color of the glow. The colors and brightnesses of the glow are also affected by the Source input.

Width Near: Default: 0.05, Range: 0 or greater.
The glow width of near (close) objects.

Width Far: Default: 0.5, Range: 0 or greater.
The glow width of far away objects.

Threshold: Default: 0, Range: 0 or greater.
Glows are generated from locations in the source clip that are brighter than this value. A value of 0.9 causes glows at only the brightest spots. A value of 0 causes glows for every non-black area.

Threshold Add Color: Default rgb: [0 0 0].
This can be used to raise the threshold on a specific color and thereby reduce the glow generated on areas of the source clip containing that color.

Layers: Integer,  Default: 5, Range: 2 to 50.
The number of depth layers to separate the source into. More layers require more processing but give smoother results in Z. More layers are sometimes needed to avoid visible seams between the layers.

Z Buffer Type: Popup menu,  Default: White is Near .
How to interpret the values in the Z buffer.
Black is Near: Black pixels in the Z buffer indicate that the object at that point is near (close to you), and white means far away.
White is Near: White pixels in the Z buffer indicate that the object at that point is near (close to you), and black means far away.

Z Buffer Use: Popup menu,  Default: Luma .
Determines how the ZBuffer input channels make a monochrome z image.
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.

Z Min: Default: 0, Range: 0 to 1.
Clamps all Z values to this minimum bound. Use this parameter to create a constant glow on all parts of the image nearer than Z Min.

Z Max: Default: 1, Range: 0 to 1.
Clamps all Z values to this maximum bound. Use this parameter to create a constant glow on all parts of the image farther than Z Max.

Width X: Default: 1, Range: 0 or greater.
Scales the horizontal glow width. Set to 0 for vertical only.

Width Y: Default: 1, Range: 0 or greater.
Scales the vertical glow width. Set to 0 for horizontal only.

Width Red: Default: 1, Range: 0 or greater.
Scales the red glow width. If the red, green, and blue widths are equal, the glows will match the color of the source clip. If they are not equal, the glows will vary in color with distance.

Width Green: Default: 1.2, Range: 0 or greater.
Scales the green glow width.

Width Blue: Default: 1.4, Range: 0 or greater.
Scales the blue glow width.

Color Near: Default rgb: [1 1 1].
Scales the glow color for near objects.

Brightness Near: Default: 1, Range: 0 or greater.
Scales the glow brightness for near objects.

Width Red Near: Default: 1, Range: 0 or greater.
Scales the red glow width for near objects.

Width Green Near: Default: 1, Range: 0 or greater.
Scales the green glow width for near objects.

Width Blue Near: Default: 1, Range: 0 or greater.
Scales the blue glow width for near objects.

Color Far: Default rgb: [1 1 1].
Scales the glow color for far objects.

Brightness Far: Default: 1, Range: 0 or greater.
Scales the glow brightness for far objects.

Width Red Far: Default: 1, Range: 0 or greater.
Scales the red glow width for far objects.

Width Green Far: Default: 1, Range: 0 or greater.
Scales the green glow width for far objects.

Width Blue Far: Default: 1, Range: 0 or greater.
Scales the blue glow width for far objects.

Affect Alpha: Default: 1, Range: 0 or greater.
If this value is positive the output Alpha channel will include some opacity from the zs. The maximum of the red, green, and blue z brightness is scaled by this value and combined with the background Alpha at each pixel.

Source Opacity: Default: 1, Range: 0 to 1.
Scales the opacity of the Source input when combined with the zs. This does not affect the generation of the zs themselves.
