BCC+ Two Way Key

Category: BCC Key and Blend

Effect Name: BCC+ Two Way Key

The BCC+ Two Way Key filter, part of the BCC Key and Blend category, 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.

Working with the Filter

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.

• View: Toggles the render view
• Output: Displays the final filtered output
• Matte: Displays the matte used for the filter.
• Matte Invert: Displays an inverted matte used for the filter.
• Mask Transparent Pixels: Displays a colored mask over the transparent pixels.
• 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
• 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

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

• 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.
