BCC RGB Edges

Category: BCC Stylize

Effect Name: BCC RGB Edges

The BCC RGB Edges filter, part of the BCC Stylize category, finds edges in each RGB channel independently, creates a new RGB image from these edges, and applies the new image to the source using the chosen Apply Mode and Apply Mix.

The results obtained with the edge filters vary depending on the media to which the filter is applied and the exact settings used. Because they create edge effects by emphasizing differences between adjacent pixels, edge filters are very sensitive to parameter adjustments. Often a small change in a parameter setting can dramatically affect the result.

Working with the Filter

Presets and Common Controls

• BCC filters come with a library of factory installed presets plus the ability to create your own custom presets and preview them with the BCC FX Browser™.
• BCC filters also include common controls that configure global effect preferences and other host-specific effect settings.

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.

• Enhance: Determines which portion of the edges is enhanced.
• Highlight: Enhances the edge highlight regions.
• Shadow: Enhances the edge shadow regions.
• Both: Enhances both the highlight and shadow regions.
• Invert RGB: Inverts the altered edges before they are applied to the source.
• Light Direction: Sets the direction that the light comes from.
• Light Elevation: Determines the elevation of the light source above the image plane. Increasing Elevation makes edge detection less directional. At an Elevation of 100, the Light Direction setting has no affect.
• Lock Intensity: Locks the Green and Blue Intensity values to the Red Intensity setting. When this option is selected, the Red Intensity parameter changes to Intensity, and the Green/Blue Intensity controls are not available. Deselect this option to adjust the three Intensity values independently.
• Red Intensity, Green Intensity, and Blue Intensity: Sets the intensity of the edges in each respective color channel.
• Lock Threshold: Locks the Green and Blue Threshold values to the Red Threshold setting. When this option is selected, the Red Threshold parameter changes to Threshold, and the Green/Blue Intensity controls are not available. Deselect this option to adjust the three Threshold values independently
• Red Threshold, Green Threshold, and Blue Threshold: Determines how sensitive the filter is to differences between pixels when finding edges in the source image. The effect of these settings depends on the nature of the source image.

• Edge Floor: The filter eliminates edges whose intensity is lower than the Edge Floor value. Use the Edge Floor control to eliminate stray edges from the output and process only the strongest edges in the image.
• Pre Blur: Blurs the source image before the edges are computed, making the edges softer.
• Lock Post Blur: Locks the Green and Blue Post Blur values to the Red Post Blur setting. When this option is selected, the Red Post Blur parameter changes to Post Blur, and the Green/Blue Post Blur controls are not available. Deselect this option to adjust the three Post Blur values independently.
• Post Blur: Sets the blur of each color channel before they are applied to the source.
• Red Post Blur, Green Post Blur, and Blue Post Blur: Determines the amount of Gaussian blur the filter applies to each of the respective color channels before the edges are applied to the source.
• Post Blur Quality: Sets the quality of the Post Blur in all three channels. Pyramid is the fastest option and is generally adequate. It produces a blur similar in quality to the Pyramid Blur filter. Pyramid Smoother produces a better quality pyramid blur and increases rendering times slightly. The remaining choices, Gaussian Low, Gaussian Medium, Gaussian High, Gaussian Higher, and Gaussian Highest produce gaussian blurs of increasing quality. These options increase rendering times proportionately.
• Make Alpha From Edges: When selected, the filter derives the image’s alpha channel from the sum of the RGB channels in the edge output.
• Reduce Flicker: Many hosts process media one field at a time which can cause flickering to occur on filtered effects. The Reduce Flicker menu allows you to reduce flicker in the rendered image. The only way to evaluate a deflicker setting is to render and play back the effect on an NTSC monitor.
• 1-2-1: Mixes each pixel with the pixels above and below it, with the input pixel getting twice the weight as the ones above and below. For After Effects users, this works the same as applying the AE Reduce Flicker filter at a setting of 0.5.
• 2-3-2: Provides more softening than 1-2-1.
• 1-1-1: Provides the most softening for effects that still contain flicker with the above options.
• Off: No deflickering will be done.
• Apply Mode: The Apply Mode menu controls how the filtered image is composited with the source image.
• Apply Mix: Determines the mix of the specified Apply Mode with the Normal apply mode. If the Apply Mode is Normal, Apply Mix has no affect and the parameter does not appear. If Apply Mix is 0, Apply Mode has no affect. Increase Apply Mix to blend the Apply Mode setting with the Normal apply mode.
• 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.
