BCC+ Chromatic Aberration
Category: BCC Lens
Effect Name: BCC+ Chromatic Aberration
The BCC+ Chromatic Aberration filter, part of the BCC Lens category, simulates chromatic aberration, which occurs when a lens bends different wavelengths of light by different amounts. This produces color fringes near high-contrast edges, especially toward the corners of the image.
The filter removes the fringing by applying distortion adjustments to individual color-channel pairs (red/cyan, green/magenta, and blue/yellow).
Note: Some color fringes are not caused by chromatic aberration (for example, purple/blue fringing from sensor overload). Your footage is more likely to contain true chromatic aberration if most of the following are true:
- Fringing is strongest in the corners, and minimal or absent in the center.
- Fringing appears on lower-contrast edges as well as overexposed edges.
- Fringing is complementary (red/cyan, green/magenta, blue/yellow) on opposite sides of bright or dark edges.
- All corners show similar fringe direction, pointing outward from the image center.
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.
Beat Reactor
The Beat Reactor is an audio-driven animation system that links effect parameters to an audio track. This allows visual effects to react dynamically to sound without manual key-framing.
For more information, see Beat Reactor Documentation.
Use the appropriate color group to correct the visible fringing. For example, if you see red/cyan fringing, start with the Red/Cyan group and adjust Distortion.
Color Groups
- Red/Cyan
- Green/Magenta
- Blue/Yellow
- Distortion: Pulls the corners of the image in or out for the selected color group. Negative values pull corners inward; positive values push corners outward.
- Anamorphic Squeeze: Corrects squeeze-related fringing typical of anamorphic motion picture lenses.
- Curvature X and Curvature Y: Corrects non-radial, asymmetric distortions often seen with anamorphic lenses.
- Center X and Center Y: Sets the center point used for the distortion correction.
Note: Anamorphic Squeeze and Curvature X/Y only take effect after you have adjusted Distortion.
- 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.
