The BCC Lens Blur Dissolve is a 100% GPU accelerated replacement to or our
original BCC Lens Transition filter. BCC Lens Blur Dissolve uses OpenCL to
deliver greatly increased render performance with a streamlined interface. It
applies a lens blur defocus/rack-focus style effect to the specular highlights
of the outgoing and incoming image clips causing the highlights take on the
shape of a simulated lens diaphragm.
This filter includes a pop-up that can be used to match different looks that
can be achieved in the physical world based on the lens aperture setting – a
pleasing optical result is referred to in photographic terms as Bokeh. Like
all of the other filters that are included in the Transitions category, BCC
Lens Blur Dissolve includes user controls for the velocity of the transition
with an optional on-screen display of the ease-in and ease-out velocity curve.
