Motion Blur

The BCC Motion Blur filter creates a realistic blur on the motion in an
image, simulating the effect of shooting a moving object on film. The blur is
based on the motion of the pixels in the image. For example, you could apply
the Motion Blur filter to a clip of a speeding car and the car’s motion would
blur while the background would not. The blur is most pronounced when the
object moves quickly and more subtle when it moves slowly.

Motion blur is not visible if the image is static.

Based upon optical flow technology, this filter examines past and future frames
to determine the motion of the pixels in the image. Depending upon the
selected settings, a blur or a smear is applied to the pixels that move from
one frame to the next. You can use an image in the timeline as a source for
motion and then apply the motion from the chosen image to the filtered track.

BCC10 introduces a new Advanced optical flow option – accessed via the Optical
Flow Method menu.  This Advanced mode uses OpenCL hardware assisted rendering
to implement a more sophisticated (and more computationally intensive) motion
vector analysis.  The performance of the Advance mode varies widely from one
graphics card to another and if you see reduced performance or unexpected
results when using the Advanced option it is recommended that you switch to
the Simple mode on that card.

The built in PixelChooser, with integrated mocha planar tracking allows for
greater control over which areas of the image the filter should affect.
