BCC Criss-Cross Wipe

Category: BCC Transitions

Effect Name: BCC Criss-Cross Wipe

The BCC Criss-Cross Wipe filter, part of the BCC Transitions group, combines two independent Multi-Stripe filters, to make wipes in a variety of patterns. At the default value, this wipe appears similar to a Grid wipe.

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.

• Background: This layer selection is not relevant when the filter is applied 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.
• Invert Wipe: When selected, the alpha channel created by the wipe inverts.
• Wipe Center: Sets the center point of the wipe on the X and Y axis.
• Direction: Sets the direction of the wipe.
• Rotation Rate: Sets the speed of the rotation.
• Softness: Sets the softness of the edges by increasing transparency in pixels that are close to the edges.
• Combine: Determines how the stripes are combined.
• Union: Renders the opacity at each point as the largest of the opacities of the two separate wipes (the horizontal and vertical stripes). When Union is chosen, the wipe may reach full opacity at a Percent Done value below 100.
• Intersect: Renders the opacity as the smallest opacity of the two separate wipes. When Intersect is chosen, the wipe may remain at full transparency at a Percent Done value significantly above 0.
• Stripes 1: Creates only horizontal stripes.
• Stripes 2: Creates only vertical stripes.
• Relative Angle: Sets the angle that the two sets of stripes make with each other.
• Relative Rotation Rate: Sets the auto-rotate of the Relative Angle parameter.
• Master Width: Scales the width controls found in each Stripe parameter group. This parameter has no affect if the Animation menu is set to Auto.
• Master Separation: Scales the separation controls found in each Stripe parameter group. This parameter has no affect if Fit Stripes to Image is selected.
• Fit Stripes to Image: When selected, the filter automatically determines the Separation Width for each group of stripes using the Angle and Stripe Count parameters. As a result, the stripes are centered in the image as long as the Wipe Center parameter remains at the image center. When this checkbox is selected, the Master Width and the Width parameters have no affect.
• Stripe Count 1: Sets the number of horizontal stripes.
• Stripe Count 2: Sets the number of vertical stripes.

Stripes Groups

Contains parameters that control the hroizontal and vertical stripes. Each group contains similiar parameters, which are determined by the Combine menu settings.

• Stripe Width: Sets the size of the corresponding stripes.
• Stripe Offset: Offsets the position of the corresponding stripes, depending on the Direction value. At the default Direction value of 90, increasing positive values move the stripes up or to the right. Decreasing negative values move the stripes down or to the left.
• Stripe Count: Sets the number of corresponding stripes that are created.
• Manual Separation: Sets the space between the corresponding stripes.
• Randomize Stripes: Adds randomization to the stripe parameter values.
• Off: Does not randomize any parameters.
• Width: Randomizes the stripe's width.
• Position: Randomizes the stripe’s position.
• Coherent Position: Adds the randomization of the previous stripe to the randomization of each successive stripe.
• Position and Width: Randomizes both the stripe's width and position.
• Coherent Pos and Width: Randomizes both the stripe's width and position, then uses the Coherent algorithm for position randomization.
• Amount: Sets the amount of randomization that is applied to the selected Randomize Stripes parameter.
• Position: Sets the amount of randomization that is applied to the stripe’s position.
• Width: Sets the amount of randomization that is applied to the stripe’s width.
• Seed: Determines the value input to the random number used by the filter to create the randomization.
• Morph Rate: Auto-animates the randomization of the stripes, so the stripe pattern automatically evolves as the effect progresses.

Gradient Group

• Gradient On: Enables modulating the wipe shape by an additional linear gradient.
• Gradient Amount: Sets the intensity of the gradient effect.
• Gradient Angle: Sets the direction of the linear gradient ramp.

Extras Group

• Output: Determines the output of the wipe.
  • Mult. Alpha: Multiplies the alpha channel created by the filter with the source alpha channel. Only areas that are opaque in both alpha channels are opaque in the output.
  • View Matte: Displays a grayscale preview of the alpha channel created by the filter. Opaque regions are white, and transparent regions are black.
  • Replace Alpha: Replaces the source alpha with the matte created by the filter.
  • Screen Alpha: Screens the alpha channel created by the filter with the source alpha channel.
  • Diff. Alpha: Subtracts the alpha channel created by the filter from the source alpha.
  • Zoom: Scales the input image to the size of the alpha channel created by the wipe.
  • Zoom Independent: Produces the same effect as Zoom, but each axis of the source scales independently.
  • Borders Only: The wipe renders only the borders.
  • Borders w Source: Renders the borders over the source image. The wipe’s alpha channel is ignored.

  Borders Group

  Used to enable up to three border groups, creating a user-defined solid border between the two clips.

• Enable Borders: Toggles the border controls for all borders.
• Master Thickness: Sets the thickness of all borders.
• Master Opacity: Sets the opacity for all the borders.
• Master Offset: Offsets the position of all borders relative to the wipe progress.

• Border On: Enables the border controls. If this checkbox is disabled, no border is created and the remaining parameters have no affect.
• Border Thickness: Sets the thickness of the border, in pixels.
• Border Opacity: Sets the opacity of the border, expressed as a percentage. The Border Color controls set the color of the border.
• Border Color: Sets the color of the border.
• Border Layer: Selects the border from another timeline layer instead of the chosen Color. If you do not assign a layer to this menu, the specified Color is used.
• Border Softness: Sets the softness of the border and is scaled to the width of the border. When Softness is 100, the border is fully opaque at its center.
• Border Balance: Sets the balance of softness between the inside and outside edge of the border. Positive values increase the softness at the outside edge, and decrease softness at the inside edge.
• Border Offset: Positions the border relative to the edge of the wipe. Negative values move the border to the left; positive values move the border to the right.

Influence Group

The Influence and Influence Map parameters allow a channel in the incoming or outgoing clip to influence the wipe.

• Influence: Turns the inflience on or off, or displays the influence map.
• Influence Intensity: Sets the intensity of the influence.
• Influence Layer: Selects the layer that is used for the influence.
• Channel: Selects the color channel that is used for the influence.
• Luma: Influence is based on the Luma Channel.
• Luma Inverted: Influence is based on the inverse of the Luma Channel.
• Alpha: Influence is based on the Alpha Channel.
• Alpha Inverted: Influence is based on the inverse of the Alpha Channel.
• Luma Difference: The outgoing clip is combined with the Luma Channel. The different pixels are chosen for the layer.
• Luma Lightest: The outgoing clip is combined with the Luma Channel. The lightest pixels are chosen for the layer.
• Luma Darkest: The outgoing clip is combined with the Luma Channel. The darkest pixels are chosen for the layer.
• Red: Influence is based on the Red Channel.
• Green: Influence is based on the Green Channel.
• Blue: Influence is based on the Blue Channel.
• Influence Threshold: Determines the value of the Influence Layer above which pixels are considered fully on. Pixels whose channel values are above the Influence Threshold level are fully on; those with channel values below the level are off.
• Influence Softness: Softens the edges of the influence by softening pixels whose values are near the Influence Threshold value.
• Blur: Sets a blur to the edges of the Influence channel before creating the wipe.
• Choke: Sets a choke to the wipe. Positive Choke values tighten the matte, while negative values expand the matte.
• Bidirectional Influence: When disabled, a positive influence value always reveals more image, and a negative value hides more. If enabled, the influence can go in both directions.

Texture Group

Smilar to the Influence controls, Texture controls allow the wipe to be influenced by a Fractal Noise Map, a White Noise map, or both. The Texture controls differ from the pattern controls in that they operate on a pixel-by-pixel basis. The Texture controls can create holes in the wipe, while the Pattern controls do not create holes.

• Texture: Determines the type of texture used in the filter.
• Off: No texture is used.
• Fractal Noise: Uses a simplified version of the algorithm used by the Noise Map filter to generate the texture.
• White Noise: Uses the algorithm used by the Pixel Noise filters combined with a high quality blur.
• Fractal and White Noise: Combines both types of texture.
• Texture Intensity: Sets the intensity of both the Fractal and White Noise.
• Fractal Intensity: Sets the intensity of the Fractal Noise texture if Fractal Noise or Fractal and White Noise are chosen in the Texture menu.
• Fractal Scale: Sets the size of the details in the Fractal Noise texture if Fractal Noise, White Noise or Fractal and White Noise are chosen in the Texture menu.
• Fractal Type: Determine the appearance of the Fractal Noise. Choose Smooth, Bubbly or Stringy.
• Fractal Flow Rate: Sets the speed of the motion of the Fractal Noise texture pattern.
• Fractal Flow Direction: Sets the direction of the motion of the Fractal Noise texture pattern.
• Fractal Morph Start: Sets the look of the Fractal Noise texture at the first frame of the effect.
• Fractal Morph Rate: Determines the rate at which the Fractal Noise texture surges and rotates inward as the filter auto-animates.
• Downsample: When set to 2, rendering is sped up by creating a smaller (downsampled) Noise map. This can make the filter appear rougher, which is useful for some effects.
Noise Intensity: Sets the intensity of the noise texture.
• Noise Softness: Sets the softness applied to the noise texture.
• Noise Seed: Determines the value input to the random number used by the filter to create the noise.
• Noise Morph Rate: Sets the rate at which the noise texture evolves over time. This allows you to auto-animate the noise texture. You can also animate this parameter between a static and evolving noise texture by animating this parameter
• Bidirectional Textures: When disabled, a positive texture value always reveals more image, and a negative value hides more. If enabled, the texture can go in both directions.

Post ProcessGroup

• Gamma: Sets the value of the mid tones while leaving the white and black of the image unaltered. The Gamma adjustment is made to the derived alpha. Increasing gamma spreads the alpha so that the matte created by the wipe is more opaque. The affect of Gamma is much more noticeable at high softness values.
• Alpha Offset: Determines an offset that is added to the output alpha.
• Post Blur: Blurs the alpha channel after the matte is created. Use Post Blur to soften the edge in the matte for sources with high contrast edges.
• Choke: Applies a choke to the matte. Positive values tighten the matte around the foreground image, while negative values pull the matte away from the edges of the foreground image.

Composite Group

• The Blend menu: Selects an apply mode to use in the blended region.
• Blend Brightness: Sets the brightness used in the blended region.
• Blend Contrast: Sets the amount of contrast used in the blended region.
• Mix With Original: Blends the source and filtered images. Use this parameter to animate the effect from the unfiltered to the filtered image without adjusting other settings, or to reduce the effect of the filter by mixing it with the source image.

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.
