BCC+ ReLight

Category: BCC Lights

Effect Name: BCC+ ReLight

The BCC+ ReLight filter, part of the BCC Lights category, allows light to be added to a scene where none existed before. A complete set of light source controls allow you to adjust the light just as you would at the time of shooting.

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.

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.

• View Sets the viewer to display different aspects of the filter.

• Output: Displays the final result of the effect.
• Matte: Displays the matte view.
• Light: Displays the light source.

Light Group

• Blend: Determines the blend mode to be used to add the light.

• Add: The light is added to the image.
• Screen: The light is combined with the image using a Screen blend mode. This looks kind of like the Add blend mode, but highlights are retained.
• Subtract: The light is subtracted from the image creating shadow instead of light.

Light Source Group

• Blend: The light source can be added to the matte using a variety of Blend modes.
• Shape Only: Displays the light source normally, without any blending.
• Add: The pixels of one image are added to another image
• Subtract: Looks at the color information in each channel and subtracts either the blend color from the base color or the base color from the blend color, depending on which has the greater brightness value. Blending with white inverts the base color values; blending with black produces no change.
• Multiply: Looks at the color information in each channel and multiplies the base color by the blend color. The result color is always a darker color. Multiplying any color with black produces black. Multiplying any color with white leaves the color unchanged.
• Screen: Looks at each images color information and multiplies the inverse of the two images. This looks kind of like the Add blend mode, but highlights are retained.
• Difference: Looks at the color information in each channel and subtracts either the blend color from the base color or the base color from the blend color, depending on which has the greater brightness value. Blending with white inverts the base color values; blending with black produces no change.
• Darken: Looks at the color information in each channel and selects the base or blend color—whichever is darker—as the result color. Pixels lighter than the blend color are replaced, and pixels darker than the blend color do not change.
• Lighten: Looks at the color information in each channel and selects the base or blend color—whichever is lighter—as the result color. Pixels darker than the blend color are replaced, and pixels lighter than the blend color do not change.

• Opacity: Sets the opacity of the light source.
• Aspect: The aspect ratio of the light source.
• Radius: The un-blurred radius of the light source.
• Falloff Radius: The blurred edge radius.
• Falloff: Moves the falloff towards the light centerpoint.
• Invert: Inverts the light source.

Transform Group

Lights can be transformed using Position, Scale, Rotate, Corner-Pin, Shear and Crop controls

• Crop: Sets the amount of cropping of the image.
• Top: Crops the image from the top down.
• Bottom: Crops the image from the bottom up.
• Left: Crops the image from left to right.
• Right: Crops the image from right to left.
• Corner Pin: The image can be corner pinned by adjusting the Corner Pin sliders as well as dragging the four points on the corners of the screen.
• Upper-Left: Controls the X and Y position of the Upper Left Point.
• Upper-Right: Controls the X and Y position of the Upper Right Point.
• Lower-Right: Controls the X and Y position of the Lower Right Point.
• Lower-Left: Controls the X and Y position of the Lower Left Point.

Note: You may need to zoom the image out a bit to see the corner points. In addition, to see and adjust the corner points in After Effects, make sure that the effect title in the Effect Controls window is highlighted. For Final Cut Pro, you must activate the cross hair icon next to the corner position parameters to see and adjust the corner points on the screen.

• Position: Sets the position of the light along the horizontal and vertical axes.
• Scale: Sets the horizontal and vertical scaling.
• Rotate: Sets the rotation of the lighting.
• Shear X: Skews left and right.
• Shear Y: Skews up and down.
• Anchor X: Defines the point on the X axis around which position, rotation, scaling or shearing takes place..
• Anchor Y: Defines the point on the Y axis around which position, rotation, scaling or shearing takes place.
• Filter: Determines the filtering method used when applying the transform to the image.
• Triangle: The Triangle filter is not the highest quality, but fine for scaled images.
• Quadratic: Quadratic is like triangle, but more blur with fewer artifacts. It offers a good compromise between speed and quality.
• Cubic: Cubic is the default filter in Photoshop. It produces better results with continuous tone images, but is slower than Quadratic. If the image contains fine details, the result may be blurrier than desired.
• Catmull-Rom: Produces good results with continuous tone images that are scaled down, creating sharp results with fine detailed images.
• Gaussian: Lacks sharpness, but is good with ringing and aliasing.
• Mitchell: A good balance between sharpness and ringing, making it a strong choice when scaling up.
• Sinc: Keeps small details when scaling down with good aliasing.

Matte Group

A matte can be used to create areas of light or limit where lights will be added.

• Extract On: allows for the selection of the type of matte.
• Luminance: A matte is created based on the luminance of the image.
• Hue: A matte is created based on the hue of the image. Adjusting the Position parameter selects different hues.
• Saturation: A matte is created based on the saturation of the image.
• Average: A matte is created based on the average of the image’s RGB values.
• Red: A matte is created based on the image’s red values.
• Green: A matte is created based on the image’s green values.
• Blue: A matte is created based on the image’s blue values.
• Cyan: A matte is created based on the image’s cyan values.
• Magenta: A matte is created based on the image’s magenta values.
• Yellow: A matte is created based on the image’s yellow values.
• Position: Pinpoints the color values to be used in the matte.
• Range: Increases or decreases the range of values in the matte.
• Blur: The matte is blurred by a quality blur.
• 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.
