Chapter 6 Working with Containers

n
For each of the first two Apply Motion Blur to options, the motion blur is computed
separately for each shape. For the last option, the snapshots are rendered for the entire
container. This provides more accurate results even if the faces do not include animated
objects; the motion blur mixing is done after the shapes are composited.
Parameter Description
Shutter Angle Refers to the workings of a conventional film camera. The
default shutter angle is 180°.
Increase the angle to open the shutter longer creating a
wider blur.
Decrease the angle to produce a thinner blur.
For the smoothest motion, set Shutter Angle to 360. You can
also overdrive it for special effects.
Smoothness Determines how many samples are taken between the time the
shutter opens and the time it closes.
Increase the number of samples to create a smoother blur.
However, preview and render times are increased
proportionally.
Low Uses the fewest samples,
Medium Limits smoothness while working in Draft mode; four
snapshots are the most rendered.
High Takes eight snapshots
Highest Uses the most samples
Apply Motion Blur to Controls what the motion blur affects.
n
Not available for 3D model containers.
3D Planes Motion Only Applies motion blur to the motion of any 3D Plane track in the
container but not to lights or shadows or to any synthetic media
or filters on the Face of the 3D Plane track.
All Shapes Applies motion blur to the motion of the Shape track as well as
to lights and shadows for any 3D Sphere, Cube, Sphere,
Cylinder, or Page Turn tracks in the container.
n
You cannot apply motion blur to Faces or filters or to
any synthetic media such as animated Natural media or
gradients.
