The BCC+ Spill Remover filter is a 32 bit hardware accelerated filter 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.
Presets and the FX Editor
The FX Editor provides a convenient way to store and retrieve factory installed and/or user generated filter presets. To select a preset, open the FX Editor interface and pick one from the Presets panel. Click the apply button in the FX Editor to return to the host user interface.
To save a custom preset, click the “Create Custom Preset” icon in the top right corner of the parameter list, next to the filter name, set a name for the new custom preset in the dialog that appears and click done.
Filter Parameters
Mocha Mask and Track provides a way for the user to select and track which pixels in the filtered source are actually going to be affected by the filter, via the generation of image based mattes, gradient mattes and vector shape masks. Mocha planar tracking and vector shape masking options are included in the PixelChooser, which allows for the generation of motion-tracked mask shapes as a hold-back mask.

Compare Mode
The BCC Compare Mode provides a convenient mechanism to compare the effect result with the original source layer. It provides several variations on basic split-screen views with the filtered clip placed next to the unedited original.

View: Toggles the render view
- Output: Displays the final filtered output
- Matte: Displays the matte used for the face tracking.
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.
Mix with Original: Blends the smoothed result back with the unfiltered source clip.
GPU Rendering: This popup allows toggles renderer in use for the filter.
- Default: By default the filter will utilize the installed video card and bases the render on the project settings.
- 16 Bit Float: Sets the render to 16 bit float
- 32 Bit Float: Sets the render to 32 bit float
- Disabled: Disables GPU rendering and switches to software rendering.
