BCC Rays Radiant Edges

Category: BCC Lights

Effect Name: BCC Rays Radiant Edges

The BCC Rays Radiant Edges filter, part of the BCC Lights category, generates light from the edges of the image.

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.

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.

Motion Tracker

The BCC Motion Tracker allows you to track the motion of an object, then use the motion path to drive other geometric properties of the effect without the need for keyframing.

• Edges From: Determines which source channel is used to create the edges and to calculate the intensities of the source pixels. Pixels with higher values in the chosen channel are considered to have higher intensities.

• Luma, Red, Green and Blue: Use the corresponding color channel and multiply it by the source alpha channel.
• Alpha: Uses the unmodified source alpha channel. If the source does not include an alpha channel, this option produces no light.
• PixelChooser: Uses the region defined in the PixelChooser.

• Edge Intensity: Adjusts the intensity of the edges before the filter searches for edges.
• Smooth Details: Blurs the source image before the filter searches for edges. This blur does not appear in the output; it is used only in edge detection.
• Bloom: Blurs the edges before they are used to create the applied light.
• Reduce Grit: Reduces noise in the image by ignoring edges that are lower than the Edge Intensity.
• Light over Edges: Composites the light over the edges, when the Apply Mode is set to something other than None. If the Apply Mode menu is set to None, enabling this checkbox will treat the Apply Mode menu as if it set to In Front.
• Edge Color: Sets the edge light color.
• Light Source: Set the location of the simulated light source on the X and Y axis.
• Intensity: Adjusts the intensity of the light source.
• Ray Length: Controls the length of the rays of light that emanate from the source. Ray Length also affects controls in the Custom Look group if the Look menu is not set to Custom.

• Ray Style: Determines what type of rays are created.

• Detailed: Produces rays that retain a great deal of detail as they spread from the Light Source.
• Fat: Produces less distinct rays.

• Look: Determines a look for the rays in the effect.

Custom Look Group

The controls in the Custom Look group customize and finetune the light rays precisely when the Look menu is set to Custom. If the Look menu is not set to Custom, these controls have no affect.

• Extend Rays: Extends the rays by favoring light pixels over dark.
• Contract Rays: Contracts the rays. While this may seem to be the opposite of Extend Rays, this parameter adjusts the algorithm differently, so increasing Contract Rays is not the same as decreasing Extend Rays.
• Holdout Radius: Determines where the rays of light start in relation to the light source. Positive values create a circular region centered around the light source beyond which the rays emanate. Attenuation does not begin until after the radius is reached. Decreasing negative values cause the attenuation to start closer to the light source point.
• Color: Determines how the applied light affects the source image.

• Colorize: Converts the light to colors using the controls in the Colorize Controls Parameter Group.
• Image: Produces a colored lighting effect using color information from the image that the filter is applied to.
• Light Matte: Uses the applied light to modify or create an alpha channel and displays a grayscale matte.
• Inverse Light Matte: Works similarly to Light Matte, but inverts the result.
• Alpha: Uses the applied light to modify or create an alpha channel and uses it to composite the source image.
• View Source: Displays the chosen Light From Channel (the source channel used by the filter to create the effect).

• Color Source: Selects the layer used when the Color menu is set to Image.
• Color Preset: Selects a colorize preset.
• Gradient: enables complex, multi-color gradients for use in a variety of effect settings such as colorizing light sources. For more information on the BCC Gradient tool, Click Here.
• Apply Mode: Determines how the filter composites the applied light with the image. For information on the available apply modes, Click Here.

Composite Group

This parameter group determine how the light is composited over the underlying image. These controls are only active when either Colorize or Use Source Color are chosen as the Light Mode menu.

• Source Threshold: Subtracts the threshold from each pixel value when computing the light.
• Light Threshold: Sets a value that is subtracted from the light at each pixel before it is applied.
• Source Opacity: Adjusts the opacity of the source image in the final composite.
• Light Opacity: Controls the opacity of the light as it is composited over the source image.
• Reduce Flicker: Many hosts process media one field at a time which can cause flickering to occur on filtered effects. The Reduce Flicker options help reduce flicker in the rendered image.

• 1-2-1: Mixes each pixel with the pixels above and below it.
• 2-3-2: Provides more softening than 1-2-1.
• 1-1-1: Provides the most softening.
• Off: The default setting.

• Mix With Original: Blends the source and filtered images.
• Light From: Determines which source color channel is used to create the light and to calculate the intensities of the source pixels.

• Luma, Red, Green, and Blue: Use the corresponding color channel and multiply it by the source alpha channel.
• Luma Inverse: Uses the inverted luma channel to create the light.
• Unmultiplied Luma and Alpha: Use the unmodified corresponding source channels.
• Luma Cartoon Edges and Alpha Cartoon Edges: Find edges in the corresponding source channel.
• Luma Edges and Alpha Edges: Find edges in the corresponding source channel.
• PixelChooser: The PixelChooser setting determines how the edges are created.

Texture Group

These parameters set and fine tune a light texture.

• Texture Intensity: Scales the selected textures.
• Stringiness: Controls the intensity of the texture.
• String Softness: Controls the softness applied to the string texture.
• String Seed: Determines the value input to the random number.
• String Morph Rate: Controls the rate at which the strings evolve.
• Shimmer Intensity: Controls the intensity of the texture.
• Shimmer Detail: Adjusts the amount of detail in the shimmer.
• Shimmer Rotate: Rotates the shimmer pattern.
• Shimmer Seed: Determines the random configuration.
• Shimmer Morph Rate: Controls the rate at which the shimmer evolves.
• Expand Source %: Expands the rays outside the outside edges of the image.
