Light Leaks Dissolve

The BCC Light Leaks Dissolve filter creates a stylized pattern of bright
lighting elements overlaid on the source footage which automatically animates
in intensity as your transition progresses to obscure the underlying dissolve
between clips.  The lighting elements simulate the look of light leaking
through the gaps in a camera and partially exposing the film/sensor.

The BCC Light Leaks Dissolve transition builds its pattern of leaks by
layering up to four separate leak generators on top of each other with
additional controls over the scaling, intensity, and apply mode of the
combined leak elements.
