Framing
Animates the camera along a path to position it in front of a selected object. You can
control how the object fits into the frame at the ending position, and you can control
the shape of the path to affect the amount of bend or curvature, as well as the apex of
such a curved path. Other parameters allow you to customize the camera’s orientation
along the path, the speed at which it travels, and at what point it begins orienting towards
the target object.
The Framing behavior has onscreen controls to allow you to manipulate the path and
ending position in the Canvas. For more information on using the Framing behavior’s
onscreen controls, see Framing Behavior Onscreen Controls.
Tip: Multiple framing behaviors can be arranged consecutively to move a camera from
one object to another over the course of a scene.
Warning: Applying a Framing behavior before or after a Basic Motion behavior, such
as Motion Path or Throw, can create unexpected results. These behaviors can continue
to affect the object even after the behavior ends. For example, If a Framing behavior is
applied after a Motion Path, the residual effect of the Motion Path is combined with the
path generated by the Framing behavior, resulting in the target object being framed
improperly. For more about Basic Motion behaviors, see Basic Motion Behaviors.
Parameters in the Inspector
Target: An image well to specify the object upon which the camera is framed.
Target Face: A pop-up menu listing the primary axes: Right (+x), Left (–x), Top (+y),
Bottom (–y), Front (+z), and Back (–z), to specify which face of the target to frame.
Up Vector: A pop-up menu providing a constraint for the camera to keep it the right
way up. The pop-up menu offers the following choices: Auto, Target +X, Target –X, Target
+Y, Target –Y, Target +Z, Target –Z, World +X, World –X, World +Y, World –Y, World +Z,
World –Z.
Auto tries to guess which axis should be pointing up, and the other choices allow the
user to specify an axis.
Framing: A pop-up menu to choose how the target should be framed. The menu choices
include:
• Fit Horizontally: Positions the camera so the full width of the target fits in the width of
the frame.
• Fit Vertically: Positions the camera so the full height of the target fits in the height of
the frame.
• Fit Both: Positions the camera so both width and height of the target fit in the frame.
