BCC+ Channel Blur Dissolve

Category: BCC Transitions

Effect Name: BCC+ Channel Blur Dissolve

The BCC+ Channel Blur Dissolve filter, part of the BCC Transitions category, creates a blur animation with options to control the level of blurring independently over each RGBA color channel. The channel blur intensity is automatically animated as 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.)
• Percent Done: Requires the user to set keyframes to control the transition progression.
• 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: Disabled/Hidden by default. When the Animation menu is changed to Percent Done then this slider can be manually keyframed to control the transition progression.

Channel Blur Group

• Blur Quality: Selects the style of the blur and the overall quality of the effect
• Box: the fastest option but with the least smooth result,
• Pyramid: offers the performance boost of a box but with some of the smoothness that approaches a gaussian. This is the default setting for the filter.
• Pyramid Smoother: an extra smoothing pass over a standard Pyramid and closer to the look of a gaussian.
• Gaussian: the smoothest result but not quite as fast as the other options.
• Blur: Determies the intensity of the blur amount. Higher values results in a more intense blur during the transition.
• Blur X: Sets the blur amount along the horizontal (X) axis.
• Blur Y: Sets the blur amount along the vertical (Y) axis.
• Blur Red: Determines the blur amount in the red color channel.
• Blur Green: Sets the blur amount in the green color channel.
• Blur Blue: Sets the blur amount in the blue color channel.
• Blur Alpha: Sets the blur amount in the alpha channel.
• Edge Mode: In some effects the filter can create instances where the image becomes offset creating areas along the edges of the frame where no image appears. Edge Mode options allow for different methods of handling those pixels.
  • 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.

Color Correction Group

The Color Correction group provides a range of color correction tools to adjust the overall look of the transition.

• Hue: Control the overall hue of the transition.
• Saturation: Used to control the overall saturation of the transition. Higher values create a more intense color saturation than lower values.
• Brightness: Used to control the overall brightness of the transition. Higher values create a more intense highlights than lower values.
• Contrast: Used to control the overall contrast of the transition. Higher values create a more intense contrast between light and dark pixels than lower values.
• Gamma: Used to control the overall gamma of the transition.
• Temperature: Used to control the overall temperature of the transition. Moving the Temperature slider to the left (negative values) will yield a cooler result, while moving the slider to the right will warm up the shot.
• Cyan/Magenta: Used to control the overall amount of cyan/magenta in the image.. Moving the slider to the left (negative values) will add a cyan tint, while moving the slider to the right will add a magenta tint.
• Red: Used to control the overall value of the red color channel. Higher values increase the overall influence of the red color channel than lower values.
• Green: Used to control the overall value of the green color channel. Higher values increase the overall influence of the blue color channel than lower values.
• Blue: Used to control the overall value of the blue color channel. Higher values increase the overall influence of the red color channel than lower values.

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.

• Glow Ease In: Control how quickly or slowly the glow amount increases at the beginning of the transition.
• Glow Ease Mid: Control the rate of change of the glow amount (how quickly it reaches its peak amount and how long it holds there) during the middle of the transition.
• Glow Ease Out: Control how quickly or slowly the glow amount decreases at the end of the transition.
• Dissolve Duration: Control 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.
• View Ease Curve: (Only visible/enabled in hosts that don’t support heads up display widgets for manipulating these controls directly on screen.) Enable this control to display a preview graph of the the animation curves rendered into in the composite window.
• GPU Rendering: allows for the selection of GPU or CPU software rendering.
  • Default: Uses the GPU to render the effect.
  • 16 bit float
  • 32 bit float
  • Disabled: disables GPU rendering and allows for CPU software rendering.
