BCC Lens Blur Dissolve

Category: BCC Transitions

Effect Name: BCC Lens Blur Dissolve

The BCC Lens Blur Dissolve filter, part of the BCC Transitions group, applies a lens blur defocus/rack-focus style effect to the specular highlights of the outgoing and incoming image clips causing the highlights take on the shape of a simulated lens diaphragm.

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.

• 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.
• 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.
• Percent Done: When the Animation menu is changed to Percent Done then this slider can be manually keyframed to control the transition progression.
• Quality: Determines the quality of the edges of the generated highlights.
• Normal: The standard, fast mode.
• Sharp: Generates a sharper result but takes longer to render than the Normal mode.
• Sharper: Generates the sharpest edges but is the slowest to render.
• Iris Scale: Sets the size of the highlight blur effect.
• Scale X: Scales the highlight along the X axis only.
• Scale Y: Scales the highlight along the Y axis only.
• Gamma: Sets the image highlight gamma.
• Blur Alpha: Determines whether or not to blur the alpha channel along with the RGB channels.

Iris Group

Contains parameters to control the shape and look of the generated highlights.

• View Iris: Displays the iris shape on a black background.
• Iris Shape: Determines the shape of the highlight.
• Circle: Generates circular highlights.
• 3-16 Sides: Generates non-circular highlights with a 3-16 sided Iris.
• Curvature: Curves or smooths non-circular iris shapes.
• Iris Rotation: Sets the rotation of the iris.
• Bokeh: Determines the look or bokeh of the Iris Shape.
• Bokeh Shading: Sets the softness of the bokeh.

Noise Group

Contains parameters to control the level of noise in the highlights.

• Noise Intensity: Sets the amount of noise in the highlights.
• Noise Scale: Sets the size of noise structure in the highlights.
• Noise Stretch: Distorts the noise structure in the highlights.
• Noise Blur: Smooths the generated noise in the highlights.
• Noise Seed: Sets the random seed that controls the noise structure in the highlights.

Highlights Group

Contains parameters to control the highlights that are generated by the filter.

• Boost/Sup Mode: Determines how the highlights are composited into the image.
• RGB Max: Boosts the RGB values of the highlights.
• RGB Glow: Boosts the RGB and Saturation values of the highlights.
• Luma Boost to White: Boosts the Luminosity values and desaturates the highlights.
• Luma: Boosts the Luminosity values of the highlights.
• Highlight Boost: Sets the intensity of the highlight boosting – higher values result in brighter highlights.
• Highlight Threshold: Sets the cut-off point for highlight boosting.
• Suppress Threshold: Sets the intensity of the shadow boosting – higher values result in darker shadows.
• Boost Soften: Softens the highlight and shadow boosting effect.

The 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.

• Damage Ease In: Controls how quickly or slowly the effect amount increases at the beginning of the transition.
• Damage Ease Mid: Controls the rate of change of the effect amount during the middle of the transition.
• Damage Ease Out: Controls how quickly or slowly the effect amount decreases at the end of the transition.
• Dissolve/Roll Duration: Controls the timing of the underlying dissolve relative to the timing of the rest of the transition.
• 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.
