NEW IN CONTINUUM 2022, the BCC+ Smear Blur filter is a more unique blur filter that simultaneously smears pixels from the filtered source forward and backward along the Z axis in a straight and/or spiral direction. This filter is GPU accelerated for smooth and speedy results.

Presets and the FX Editor

To select from a selection of factory installed and user-generated presets, open the FX Editor interface and pick one from the Presets window.

Filter Parameters

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.

Smooth Mode: select the method of smoothing used in the effect.

• Automatic: Lets the filter set the level of smoothness in the image samples
• Manual: Manually sets the level of smoothness in the image samples

Smoothness: Sets the level of smoothness in the image samples when in manual mode

The Transformation Group

• Global Transform: Globally adjusts all values in the transformation group allowing for simple, one parameter keyframing or adjustments.
• Lock Center Start/End: when checked the the center start and center end parameters will be bound to each other.
• Center Start: Sets the center point of the start of the blur.
• Center End: Sets the center point of the end of the blur.
• Scale Start: Manually sets the start point of the blur along the z axis.
• Scale Start X: Manually sets the start point of the blur along the x axis.
• Scale Start Y: Manually sets the start point of the blur along the y axis.
• Scale End: Sets the end point of the blur along the z axis.
• Scale End X: Sets the end point of the blur along the x axis.
• Scale End Y: Sets the end point of the blur along the y axis.
• Angle Start: Sets the start angle of the blur rotation.
• Angle End: Sets the end angle of the blur rotation.
• Offset Start: Offsets the start result along the z axis.
• Offset End: Offsets the end result along the z axis.

Falloff : Controls the bias of the blur falloff between the start and end for both position and angle

Apply Mode: Select from 24 apply/blending modes.

Apply Mix – Mix selected apply mode back with normal apply mode.

Edge Mode: used to control the look of the edge of the blurred result.

• 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.

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.

PixelChooser:The BCC PixelChooser provides simple, built-in masking of the effect result.  The PixelChooser is generally used to select a portion of the image and restrict an effect to just the selected area while maintaining the original image content in unselected regions.  The selection can be based on geometric shapes or on the image’s luma/color properties.
