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. Inputs: Source:  The clip to be processed.

Parameters:

Blur Amount1:   Default: 0.1,  Range: 0 or greater.
The width for the first blur. Sets the low frequency cutoff. This parameter can be adjusted using the Blur Amount1 Widget.

Blur Amount2:   Default: 0.2,  Range: 0 or greater.
The width for the second blur. Sets the high frequency cutoff. This parameter can be adjusted using the Blur Amount2 Widget.

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. This parameter can be adjusted using the Blur Amount1 Widget.

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

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

Offset Darks:   Default: 0.5,  Range: any.
