BCC+ Edge Composite

Category: BCC Key and Blend

Effect Name: BCC Edge Composite

The BCC+ Edge Composite filter, part of the BCC Key and Blend category, automatically generates an edge matte from an existing Alpha channel and allows you to color correct or blur only the edge of the foreground. You can also mix the edge of the foreground with the background. This is very helpful for seamlessly integrating images as well as dealing with aliased mattes.

Working with the Filter

FX Editor and Presets

• Use the FX Editor to load or save presets for reuse.
• To load a preset: Open the FX Editor, select a preset from the Presets panel, and click Apply to return to the host application.
• To save a custom preset: While in the FX Editor, click the Create Custom Preset icon in the parameter list, enter a preset name, and click Done. Additionally, a custom preset can be saved from the main menu bar by selecting File->Save Preset.

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: Selects the output view for the filter.
• OutputDisplays the final output for the effect.
• MatteDisplays the matte used for the effect.
• EdgeDisplays the edge used in the composite.
• Side: Determines the size of the edge matte.
• Hue: Rotates the hue of the image.
• Saturation: Adjusts the saturation of the image*.*Positive values saturate, negative values desaturate.
• Brightness: Adjusts the brightness of the image. Positive values brighten, negative values darken.
• Contrast: Adjusts the contrast of the image. Positive values increase contrast, negative values decrease contrast.
• Gamma: Adjusts the gamma of the image. The gamma adjustment leaves the white and black points the same and only modifies the values in-between. Positive values lighten the midtones, negative values darken the midtones.
• Temperature: Sets the color of the image to be either warmer or cooler. Dragging the slider to the right makes the image cooler (bluer) and dragging the slider to the left makes the image warmer (redder).
• Cyan/Magenta: Adds either Cyan or Magenta to the image. Dragging the slider to the right makes the image more magenta and dragging the slider to the left makes the image more cyan.
• Red: Adds or subtracts red from the image.
• Green: Adds or subtracts green from the image.
• Blue: Adds or subtracts blue from the image.
• Blur X: The edge of the composite is blurred along the X-axis.
• Blur Y: The edge of the composite is blurred by a fast along the Y-axis.
• Gang: The horizontal and vertical slider values can be ganged together. Adjust the horizontal slider to affect both values.
• Opacity: Mixes the foreground back to the background, but only in areas of the edge matte.

• 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.
