The BCC+ Two Way Key filter, with a 32 bit float pipeline and full hardware rendering on on all supported platforms is a drop in replacement for the now legacy BCC Two Way Keyer. The Two Way Key creates an alpha channel key based on user defined key color to determine which color to key out and a user defined keep color to restore opacity to selected colors in the range. A similarity option allows users to expand and contract the key regions. This filter also includes a full Pixel Chooser with Mocha option for object isolation and garbage masking. The Linear Color Key also allows you to remove unwanted foreground objects or restore opacity to a transparent region in the foreground using the Region of Interest controls.
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.
- Overlay: Displays a color overlay within the mask region.
Output: use to set the filters render output
- Key: renders the keyed image result
- Key Invert: inverts the key and renders the keyed image result
- Matte: renders only the generated matte result
- Matte Invert: inverts the matte and renders the generated matte result
- Gel: renders the gel result
- Gel Invert: inverts the matte and renders the gel result
- Keep Color: useful only when the image already has an alpha channel. It is used to restore opacity to regions that have been made transparent
Gel Color: Used to select the gel color
Key Color: Used to set the base key color
Similarity: Used to expand the key color selection
Keep Color: Used to set the base keep color
Keep Similarity: Used to expand the keep color selection
Softness: Used to soften the generated key matte within the key color
Post Blur: Used to add a blur to the current key matte
Gamma: Gamma correction for the generated key matte
Alpha Offset: Used to offset the alpha matte values. Negative values will add transparency to the matte, positive values return opacity to the matte
Choke: Used to shrink/expand the alpha matte
The Region Group
Region of Interest: The Region of Interest setting determines the shape of the region in which the filter is applied. You can apply the filter to an area Inside Rectangle, Outside Rectangular, Inside Oval, Outside Oval, or choose All to filter all pixels in the image, regardless of their location.
- Inside Rectangle: Confines the filter result to the region inside the rectangle shape bounds
- Outside Rectangle: Confines the filter result to the region outside the rectangle shape bounds
- Inside Oval: Confines the filter result to the region inside the oval shape bounds
- Outside Oval: Confines the filter result to the region inside the oval shape bounds
- All: ROI is bypassed and the entire image source is included in the key matte generation
Top-Left x/y: Sets the top-left position of the region along the x/y axis.
Bot-Right xy: Sets the bottom-right position of the region along the x/y axis.
Outside Region: Used to control the processing of points outside the region. e
- Crop: Preexisting alpha channel values are cropped to within the ROI
- Use Existing Alpha: Existing alpha channel values outside of the ROI are preserved
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.
