BCC Grid Wipe

Category: BCC Transitions

Effect Name: BCC Grid Wipe

The BCC Grid Wipe filter, part of the BCC Transitions group, uses a cross hatched pattern which expands from a center point to progressively wipe the image off screen.

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.
• Center: Sets the center point for the transition and hub of any specified rotation.
• Rotation: Sets the amount of rotation applied to the cross hatch pattern.
• Border: Controls the width of the border region between the inside and outside of the shape and thus effectively the type of tapering that appears in the cross hatch elements as they reach progress towards the edges. Higher values produce wider borders between the inside and outside of the shape leading to more slowly tapering cross hatch elements. Lower values produce narrower borders with more rapid tapering.
• Tiles: Set the total number of tiles in the grid with higher values producing a denser cross hatch pattern.
• Transition Type: Sets the shape of the overall pattern boundary as it grows from the center point.
  • Doors – splits the source image into two parts.
  • Radial – wipes in a circular shape.
  • Rectangular – wipes in a rectangular shape.
• Invert Wipe: Reverses the direction of the wipe so that it expands from the outside towards the center point instead of from the center point outwards.
• Opaque Sources: When enabled, this tells the transition that it is applied to opaque images and thus for example that it is OK to apply the Drop Shadow (which is only supported when working with opaque clips). If working with titles or other clips containing alpha objects you must disable this checkbox to ensure proper transition behavior.

Drop Shadow Group

Adds depth to the transition with a drop shadow between the upper and lower layers as the opacity of the upper layer is modified by the wipe pattern. This feature is only supported when working with opaque clips.

• Drop Shadow On: Enable/Disable the drop shadow feature.
• Color: Sets the color of the drop shadow.
• Strength: Sets the strength (or effective opacity) of the drop shadow.
• Direction: Sets the angle in which the drop shadow is offset from the image.
• Distance: Sets how far the drop shadow shifts from the feature casting it.
• Softness: Sets how defocused the drop shadow appears to be. Higher values produce shadows with softer edges.

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.

• Ease In: Controls how quickly or slowly the effect amount increases at the beginning of the transition.
• Ease Out: Controls how quickly or slowly the effect amount decreases at the end 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.
