BCC+ Spill Remover

Category: BCC Key and Blend

Effect Name: BCC+ Spill Remover

The BCC+ Spill Remover filter, part of the BCC Key and Blend category, that is an advanced and highly efficient method of removing spill from green, blue and red backgrounds while keying footage. It prevents background color from seeping into the foreground by suppressing those tones, or by creating a color or image light wrap around the areas of spill.

Spill Remover is available as a stand alone filter, as well as an additional feature inside of BCC Primatte Studio.

Effect Controls

Mocha Mask and Track

Continuum effects include integrated masking and matte tools that allow you to restrict the effect to specific regions of the image.

• Mocha masks: used to create custom spline masks. Mocha also includes Matte Assist ML and Matte Refine ML, which use machine learning to generate and track masks.
• Pixel Chooser: used to generate geometric shapes, gradients, or mattes based on channel, luma, or color-based selections. Additionally, an AI depth map generator, and an AI-powered face detection model allow for precise control of masks and mattes.

For more information, see Mocha and Pixel Chooser.

Compare Mode

The Compare Mode is used to view the filtered result alongside the original source layer. Several split-screen and side-by-side display options are available.

For more information, see Compare Mode.

• Amount: Used to adjust the overall amount of spill removal
• Spill Replace Mode: Used to set the style of the spill removal.
• Channel Limit: Scans the selected color channel and attempts to remove the spill. You can set the Screen Type pop-up to have the filter remove green, blue or red spill and adjust the Bias to adjust the replacement color tones.
• Classic Continuum: Uses the classic BCC Spill remover method of removal.
• Screen Type: Used to manually select the screen color and adjust the removal mix. Available options include:
• green
• blue
• red
• Bias: Used to adjust the Bias to adjust the replacement color tones.
• Bias Fixed Channel: Used to set the bias to a fixed channel.
• Screen Color: Used to set the color of the spill you wish to remove.
• Spill Ratio: Used to adjust the Spill Ratio until most of the background color is gone from the foreground. Lowering Spill Ratio to 0 creates a magenta (if the key color is green) or yellow (if the key color is blue) tint in the foreground. Increasing this value to 200 leaves the original foreground color unchanged, with no adjustment for spill.
• Spill Tone Mix: Has the opposite effect of Spill Ratio; it adds background color to the foreground image. For example, if you work with a green screen image, you can increase Tone Mix to compensate for magenta tint created by lowering the Spill Ratio.
• Spill Tone Range: Increasing Spill Tone Range increases the range of the foreground color mix, which can also help restore the original color to the flesh areas.
• GPU Rendering:Specifies how the effect is rendered.
• Default: Uses product-wide default of 16 bit half-float GPU rendering.
• 16 Bit Float: Manually force 16 bit half-float GPU rendering.
• 32 Bit Float: Manually force 32 bit full-float GPU rendering.
• Disabled: Forces CPU rendering.
