Flare 1 Settings
Cool
Restores cooler colors, such as blue, green and cyan.
Skin Tone
Restores the color of natural skin tones that may have been changed by spill
suppression.
Light Warm
When advanced flare is enabled, this setting recovers lighter, warmer colors,
such as red, yellow and orange. This setting interacts with the skin tones setting.
Black, Gray and White Balance
Use this setting to color correct the spill suppression in the tonal regions of the
foreground, such as the shadows, mid tones and highlights.
Flare Level
When advanced flare controls are enabled, this setting adjusts the overall amount
of spill suppression for certain foreground colors.
Holdout Matte Flare Button
When a holdout matte is used to stop the compositing process in portions of the
foreground scene, spill suppression on the foreground becomes slightly more
complicated. In some situations, removing spill suppression from the entire scene
would result in a more convincing look. In other situations, no spill suppression in the
holdout matte area would be the best choice.
When holdout matte flare is disabled, spill suppression is not performed in
the holdout matte region. When enabled, spill suppression is removed from the entire
foreground scene.
Flare 2 Settings
Flare Correct Horizontal or Vertical Size
Flare correction analyzes the spill suppression in the transition areas and lets you make
subtle corrections. For example, neutralizing small color discrepancies, or luminance
variations that may be affecting fine edges in the transition area.
You can adjust the size of the area around the pixels of interest that Ultimatte will use to
analyze the spill suppression. This area is defined via pixel width and line height. When
the size is set to 0, no flare correction is applied.
Dark Warm
When advanced flare is enabled, this control can help to restore brown colors,
for green screen, and purple colors, for blue screen. This control interacts with skin
tones settings.
Flare Reset
Tap this button to reset all flare controls to their default settings, depending on the backing
color selected.
Advanced Flare
If you are adding Ultimatte 12 to an existing system using Ultimatte 11 units and you want to
maintain a consistent look between them, you can disable the advanced flare features in
Ultimatte 12 and use standard flare processing. This sets the flare controls and spill suppression
in Ultimatte 12 to match the standard features in Ultimatte 11 units which will maintain
consistency in the image when switching between multiple units.
