S_BandPass Generates an X-ray-like effect using a band-pass filter. Two blurs are performed with different widths, and the result is the difference scaled and offset by a gray value. Frequencies above and below the cutoffs are attenuated, leaving only the middle band of frequencies. In the Sapphire Stylize effects submenu. Inputs: Source:  The current layer.   The clip to be processed.

Parameters:

Blur Amount1:   Default: 10,  Range: 0 or greater.
The width for the first blur. Sets the low frequency cutoff.

Blur Amount2:   Default: 20,  Range: 0 or greater.
The width for the second blur. Sets the high frequency cutoff.

Blur Rel:   X & Y,   Default: [1 1],  Range: 0 or greater.
The relative horizontal and vertical blur widths. Set Blur Rel X to 0 for a vertical-only blur, or set Blur Rel Y to 0 for a horizontal-only blur.

Brightness:   Default: 3,  Range: any.
Scales the brightness of the result.

Saturation:   Default: 1,  Range: -2 to 8.
Scales the color saturation. Increase for more intense colors. Set to 0 for monochrome.

Offset Darks:   Default: 0.5,  Range: -5 to 5.
Adds this gray value to the darker regions of the result. This can be negative to increase contrast.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

All Opaque:  Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).

Normal:  Process opacity normally.

As Premult:  Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.

Show Blur Amount1: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Opacity parameter.This parameter only appears on AE and Premiere, where on-screen widgets are supported.

Show Blur Amount2: Check-box, Default: off.
