NEW IN CONTINUUM 2022, the BCC+ Channel Blur YUV filter allows for the bluring of an image with options to control the level of blurring independently over each YUV and Alpha channels in the filtered source.
The YUV model defines a color space in terms of one luma component (Y) and two chrominance components, called U (blue projection) and V (red projection) respectively. 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.
Blur Quality: Selects the style of the blur and the overall quality of the effect
- Box: the fastest option but with the least smooth result.
- Pyramid: offers the performance boost of a box but with some of the smoothness that approaches a gaussian.
- Pyramid Smoother: an extra smoothing pass over a standard Pyramid and closer to the look of a gaussian.
- Gaussian: the smoothest result but not quite as fast as the other options.
Blur: Adjusts the master blur amount.
Blur X: increases the blur amount along the horizontal axis.
Blur Y: increases the blur amount along the vertical axis.
Blur Luma Y: controls the blur amount in the luma (Y) channel.
Blur U: controls the blur amount in the U (blue projection) channel.
Blur V: controls the blur amount in the V (red projection) channel.
Blur Alpha: controls the blur amount in the alpha channel.
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.
