Use the Spill Hue slider to select the central, or base, color for spill suppress correction.If your foreground image contains bright-colored areas that are suffering fromīackground spill, decrease the clip value to have it corrected. Decreasing the clip value includes higher-saturated colors in spill suppress correction.Increasing the clip value removes higher-saturated colors from spill suppress correction.Use the Spill Clip slider to adjust spill suppress clipping.These excluded colors move back into the translucent area. Decreasing the range value narrows the shadow area by excluding high-luminance colors.The increased range comes as a result of colors moving from the translucent Increasing the range value widens the shadow area by including lower-luminance background colors.Use the Shadow Range slider to adjust the range of the shadow colors.
Decreasing the gain value creates lighter shadows.Increasing the gain value creates darker shadows.Use the Shadow Gain slider to adjust the shadow appearance.Decreasing the reflections value decreases the brightness of semi-transparent reflections.Increasing the reflections value increases the brightness of semi-transparent reflections.Use the Luminance Reflection slider to change the brightness of semi-transparent reflections (like reflections from glasses).Decreasing the background suppress value decreases the brightness of Background, Translucent, and Transition areas.Increasing the background suppress value increases the brightness of Background, Translucent, and Transition areas.Use the Background Suppress slider to change the overall brightness of Shadow, Translucent, and Transition areas.Decreasing the reject value increases the amount of adjacent hues that are included in the foreground.Increasing the reject value decreases the amount of adjacent hues that are included in the foreground.Use the Foreground Reject slider to include or reject hues adjacent to the base color.Decreasing the hue value moves clockwise around the color wheel to select a base color.Increasing the hue value moves counter-clockwise around the color wheel to select a base color.Use the Foreground Hue slider to select the central (base) color for the foreground.Decreasing the clip value includes lower-saturated colors in the Foreground image.Increasing the clip value removes lower-saturated colors from the Foreground image.Use the Foreground Clip slider to adjust the foreground clipping.Decreasing the softness value decreases the amount of softness applied to the foreground edges and alpha channel.Increasing the softness value increases the amount of softness applied to the foreground edges and alpha channel.Use the Edge Softness slider to add or remove edge softening of the foreground image and alpha channel.Decreasing the saturation range value includes a narrower range of saturation values to be included in the background.Increasing the saturation range value includes a wider range of saturation values to be included in the background.Use the Background Sat slider to adjust the saturation range of the background color.Use the Background Pos Hue slider to adjust the range of hues that are included in the Background, expanding clockwise around the color wheel.Use the Background Neg Hue slider to adjust the range of hues that are included in the Background, expanding counter-clockwise around the color wheel.On - Include the maximum detail in the edges of the chroma key.
Off - Reduces the level of detail in the edges of the chroma key as well as the overall noise in the key image that can be the result of certain lightingĬonditions or high detail camera settings.Click an Additive Keying button to turn it on or off.Every time the key is initialized, the switcher resets all the Chroma Key parameters to their default settings.
