free update for Boris Continuum Complete 6 FxPlug users.
It’s an an auto-animating filter that uses bursts of synchronized
Exposure, Glow, Blur, X or Y displacement, and RGB channel offset to
create a flicker effect for video or graphics elements. The flicker
effect has been made popular by recent television commercials and
film trailers.
Flicker and Shake works in Apple Final Cut Pro and Motion. The filter
is part of the Boris Continuum Shaders category of real-time FxPlug
filters that take advantage of the latest Mac OS X OpenGL technology.
