BCC Trails Basic

Category: BCC Time

Effect Name: BCC Trails Basic

The BCC Trails Basic filter, part of the BCC Time category, creates motion trails, video echoes, and video feedback effects which can be combined in a variety of ways.

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.

• Source Layer: The Source Layer menu sets the clip used to create the effect.

Source Group

• Crop Top-Left: Sets the upper left point of the rectangular crop area.
• Crop Bot-Right: Sets the bottom right point of the rectangular crop area.

Geometry Group

The Geometry group adjusts the source’s size and position and rotate the source around the X, Y, and Z axis.

• Lock to Scale X: Links the scale x and scale y parameters, so that scale asjustments remain proportional.
• Scale X Source: Sets the size of the source along the x axis.
• Scale Y Source: Sets the size of the source along the y axis.
• Position XY Source: Sets the X and Y coordinates of the center point of the source.
• Position Z Source: Adjusts the apparent depth of the source. Decreasing negative values move the source closer to the viewer, while increasing positive values move the source farther away from the viewer.
• Tumble Source, Spin Source, and Rotate Source: move the source around the X, Y, and Z axis, respectively. Tumble, Spin, and Rotate can be animated over values greater than 360° in order to make the source complete more than one full revolution.

Trails Group

The Trails parameters add motion trails to the effect and provide a variety of options for adjusting the trails’ behavior and appearance.

• Frame Separation: Sets the distance between each motion trail and the adjacent trail and/or source image. This value measures the number of frames between each trail and the frame from which the trail is created.
• Trail Count: Determines the number of trails that are visible in the effect.
• Trails Before Start: Determines whether or not the effect displays trail frames that are created before the first frame of the source layer.
• Trail Intensity: Sets the opacity of the trails.
• Blur: Sets the blur of the trails.
• Blur Quality: Selects the style of the blur and the overall quality of the effect
  • Gaussian Low: the fastest option but with the least smooth result.
  • Gaussian Medium: a fast option with the smoother results.
  • Gaussian High: A balance of performance and quality.
  • Gaussian Higher: A higher quality blur, but with increased render speed.
  • Gaussian Highest: The highest quality but with the largest impact on render speed.
  • Pyramid: Offers the performance boost of a box blur 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.
• Auto Fade: When selected, the trails automatically fade evenly so that the first trail is entirely opaque and the last trail is almost entirely transparent.
• Manual Fade: When Auto Fade is deselected, Manual Fade sets the ratio of the opacity of each trail to the opacity of the following trail.

Trail Feedback Group

• Scale Feedback: Sets the sizes of the trails.
• Position Offset Feedback: Affects the XY position of the trails.
• Position Z Feedback: Displaces the trails along the Z axis.
• Tumble Feedback, Spin Feedback, and Rotate Feedback: Rotates the trails around the X, Y, and Z axis respectively.

Composite Group

• Apply Mode: determines how the trails and source layer are composited.
• Apply Mix: blends the Apply Mode setting with the Apply Mix From setting.

• Use Apply Settings: determines which elements are affected by Apply Mode and Apply Mix.
• Trails and Composite: Applies the settings to both the trails and the source layer.
• Trails Only: Applies the settings to the trails only, leaving the source layer unaffected.
• Composite Only: Applies the settings to the source layer only.
• Ignore: Disregards the settings and applies the effect normally to both the trails and the source layer.
• Composite Trails: Controls how the trails overlap the source.
• In Front: Composites the trails in front of the source layer.
• Behind: Composites the trails behind the source layer.
• Trails Only: Composites the trails only, removing the source layer from the effect.
• Render Order: Determines how the trails overlap each other.
• Oldest in Front: Places each successive trail in front of the previous trail.
• Youngest in Front: Place each successive trail behind the previous trail.
• Source Opacity: Sets the opacity of the source layer in the filtered output and does not affect the trails.
