• Output: Selects which aspect of the filter is displayed.
• Composite: Displays the composited effect.
• Show Matte: Displays the matte used in the effect.
• Blend: Sets the amount of blur applied to the matte after level adjustments.
• Choke: Sets the size of the opaque portion of the matte. Positive values expand the opaque areas, while negative values contract them.
• Black: Sets the alpha values in the matte that are treated as pure black (transparent) by the filter. All pixels whose alpha value is lower than the Black value are output as transparent.
• White: Sets the alpha values in the matte that are treated as pure white (opaque) by the filter. All pixels whose alpha value is higher than the White value are output as opaque.
• Spread: Sets the width of the edge area used in making level adjustments.
• Gain: Sets the maximum variance permitted within the edge area before the black and white thresholds are tested. Increasing Gain heightens the effect of changes to the Black and White parameters.

• Region of Interest Bot-Right: Sets the bottom right corners of a rectangle within which the filter is applied.
