BCC+ Non-Additive Mix
Category: BCC Key and Blend
Effect Name: BCC Non-Additive Mix
The BCC+ Non-Additive Mix filter, part of the BCC Key and Blend category, combines two images by controlling their luminance level relative to each other as well as a set mix percentage. Back in the day of video switchers and online editing, effects editors used a non-additive mix to combine smoke and fire to another image.
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.
- To import custom presets from another drive: While in the FX Editor, select File->Import Preset from the main menu bar.
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.
Note: Mocha can also be used to drive geometric parameters. See the Mocha Motion Tracker documentation for details.
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.
- Output: Displays the final output for the effect.
- Foreground: Displays the foreground layer.
- Background: Displays the background layer.
- Background: Selects what image to use as the background.
- Mix: Sets the mix level of the foreground element.
- Black Clip: Blacks are made blacker by increasing the value of the slider. As the slider value increases, more values are clipped to black.
Note: Often times the black portion of an image is not entirely black. This becomes an issue if something like fire is shot against a black background. If the black is not entirely black, then these impure black areas will be added to the background image as part of the Holdout Composite causing the final result to have milky blacks. Black Clip will improve these milky blacks and make them darker.
- Mix with Original: Blends the source and filtered images. Use this parameter to animate the effect from the unfiltered to the filtered image without adjusting other settings, or to reduce the effect of the filter by mixing it with the source image.
- 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.
