BCC+ Film Glow Dissolve

Category: BCC Transitions

Effect Name: BCC+ Film Glow Dissolve

The BCC+ Film Glow Dissolve filter, part of the BCC Transitions category, generates a traditional film glow look that automatically increases in intensity as it animates the transition progresses to obscure the dissolve between clips.

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.

• Animation: Menu controlling what drives the animation of the transition.
• Auto: Automatically generates a transition based on the transition length (when used as a transition) or the clip length (when used as a filter).
• Manual: Requires the user to set keyframes to control the transition progression. Can be useful in customizing the exact timing of the transition or when applying the filter as a stylized effect as opposed to a direct NLE-style transition.
• Layer to Reveal: This layer selection popup is not relevant when you have applied the filter as a true NLE-style transition and it will be hidden or disabled in that context. When applied as a normal “effect” as opposed to a transition, however, this menu is used to select the “Incoming” or “Reveal” layer for the transition.
• Percent Done: When the Animation menu is changed to Percent Done then this slider can be manually keyframed to control the transition progression.

Film Glow Group

• View: This four way pop-up is useful when setting up the filter:
  • Output: This is the main result of the full glow effect applied back over the input clip
  • Glow: Displays just the generated glow prior to being applied back to the input clip via the apply modes.
  • Threshold: Displays the intermediate result of the threshold setting
  • Threshold w Boost + Desat: Displays the intermediate result of the Threshold with Boost and Glow Desaturation applied
• Glow Intensity:Sets the intensity of the glow result.
• Glow Color: Determines the color of the glow. In it’s default state the glow is white. By selecting a color with the color chip, the glow can be set to any RGB value. With the eyedropper, the glow color can be selected directly from the image pixels.
• Glow Radius:Sets the radius over which the glow spreads to surrounding regions. Higher values will result in a larger, more diffuse glow, while lower values will create a more restricted glow.
• Glow Radius X: Sets the width of the glow along the X axis. Higher values will result in a glow that is stretched horizontally along the X axis, while lower values will restrict the glow horizontally along the X axis.
• Glow Radius Y :Sets the width of the glow along the Y axis. Higher values will result in a glow that is stretched vertically along the Y axis, while lower values will restrict the glow horizontally along the Y axis..
• Glow Desaturation:Modifies the glow result by adjusting the chroma values that are used for the input. At 0 the function has no effect on the result generating a traditional film glow, increasing the value in this parameter yields a result that looks colder and less saturated.
• Glow Threshold:Sets the pixel values that are affected by the glow – a setting of 0 will apply a glow to all of the pixels in the input clip, while a setting of 100 will not apply any glow to the image.
• Glow From Alpha:Generates the image glow from the alpha channel instead of or in addition to the color channels. The selection in the Glow From Alpha Mode determines how the alpha glow and the color channel glows are combined.
• Glow Boost Alpha:Determines how much the spread of glow pixels caused by the blur boosts the alpha channel of non‐opaque pixels.
• Glow Under Source: Use this function to control how the glow is composited with source clips – a setting of zero composites the glow on top of the source and disregards the source alpha channel, while a setting of 100 composites the glow behind opaque regions in the source but allowing it to extend out into the transparent regions.
• Edge Handling: Determines how edges of the filtered frame are handled.
  • Transparent: allows the edge of the result to become transparent.
  • Repeat: repeats edge pixels to generate opaque pixels along the edge of the result.
  • Reflect: reflects pixels back into the result to generate opaque pixels along the edge of the result.
  • Warp: warps edge pixels to generate opaque pixels along the edge of the result.
• RGB Independent Glows:Enables independent scaling of the glow dimensions for R, G, and B.
• Red Scale: Sets the scale of the red glow uniformly. Higher values will increase the scale along the X and Y axis.
• Red Scale X: Sets the scale of the red glow along the horizontal axis. Higher values will increase the scale along the X axis. While lower values will restrict it.
• Red Scale Y: Sets the scale of the red glow along the vertical axis. Higher values will increase the scale along the Y axis. While lower values will restrict it.
• Green Scale: Sets the scale of the green glow uniformly. Higher values will increase the scale along the X and Y axis.
• Green Scale X: Sets the scale of the green glow along the horizontal axis. Higher values will increase the scale along the X axis. while lower values will restrict it. .
• Green Scale Y: Sets the scale of the green glow along the vertical axis. Higher values will increase the scale along the Y axis. while lower values will restrict it.
• Blue Scale:Sets the scale of the blue glow uniformly. Higher values will increase the scale along the X and Y axis.
• Blue Scale X: Sets the scale of the green glow along the horizontal axis. Higher values will increase the scale along the X axis. While lower values will restrict it. .
• Blue Scale Y: Sets the scale of the blue glow along the vertical axis. Higher values will increase the scale along the y axis. While lower values will restrict it.
• Glow Matte Type: Selects the channel in the source image from which the glow is derived. Pixels with higher values in the selected channel are considered to have higher intensities.
  • Color: use the RGBA color channel and multiplies it by the source alpha channel.
  • Color Inverted: uses the inverted color channel.
  • Luma: uses the luma channel.
  • Luma Inverted: uses the inverted luma channel.
  • Alpha: use the unmodified Alpha channel.
  • Alpha Inverted: use the inverted Alpha channel.

Extras Group

• Threshold Color:The RGB values of this color are added to the threshold slider value to make an independent threshold for each channel. (e.g. if this is set to pure blue, the blue channel is not glowed, regardless of the channel values or the threshold slider setting.)
• Glow Apply Mode: Sets the apply mode that the filter uses to composite the glow over the input image. The default apply mode is “Screen”.

Color Correct Group

A suite of color correction tools are available in this group which allow for incredible control over the final color of the effect. Bear in mind that these controls will control the final result, including the filtered source. Every stage of the effect that is before this stage will be subject to color changes made in this section.

• Hue: Rotates the hue of the image.
• Saturation: Sets the saturation of the image.
• Brightness: Sets the brightness of the image.
• Contrast: Sets the contrast of the image.
• Gamma: Sets the gamma of the image.
• Temperature: Sets the color of the image to be either warmer or cooler.
• Cyan/Magenta: Adds either Cyan or Magenta to the image. Dragging the slider to the right makes the image more magenta and dragging the slider to the left makes the image more cyan.
• Red: Adds or subtracts red from the image.
• Green: Adds or subtracts green from the image.
• Blue: Adds or subtracts blue from the image.

Animation Tuning Group

These parameters control the overall timing of the transition. On hosts which permit on-screen heads up display widgets (such as AE, Premiere, and Avid) you should never need to modify these sliders directly since they can be configured in a more convenient and intuitive manner by manipulating the widgets directly in your comp/preview pane. On hosts without heads up display widgets you can use these sliders directly to fine tune your animation timing, taking advantage of the View Ease Curve option to help visualize the animation rates.

• Ease In: Controls how quickly or slowly the effect advances at the beginning of the transition.
• Ease Mid: Controls how quickly or slowly the middle of the animation progresses.
• Ease Out: Controls how quickly or slowly the effect advances at the end of the transition.
• Dissolve Duration: Controls the timing of the underlying dissolve relative to the timing of the rest of the transition.
• OSC Enable: Only visible in hosts that support heads up display widgets for manipulating these controls directly on screen. Enables/Disables on screen controls.
• 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.
