The BCC Glow Alpha Edges filter applies a glow that adheres closely to the
contours of the image clip’s alpha channel or mask. This filter is designed for
use with masks or images that have an alpha channel.
The built in PixelChooser, with integrated mocha planar tracking allows for
greater control over which areas of the image the filter should affect.
