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.

• Simple Fit: Positions the camera so both width and height of the project fit in the frame.
If the target object is larger or smaller than the project dimensions, it may not properly
fill the frame.
• Custom Fit: This option appears when the Framing Offset parameter is manipulated
manually.
Framing Offset:
Three value sliders (X, Y, and, when expanded, Z) to offset (in pixels) the
point on the target that is centered, relative to the camera. This allows you to target a
point other than the center of the object. The Z slider moves the camera nearer to or
farther from the target.
Offset Path Apex:
A slider to set the position along the path (from the original position
to the framing position) where the bend (if any) occurs if the user chooses to offset the
path. It is expressed as a value between 0 and 1 (0 being at the start of the path, 1 at the
end, and 0.5 being halfway along the path).
Path Offset:
Three value sliders (X, Y, and when expanded, Z) to offset the camera’s
position from the path, measured in pixels.
Orientation:
A pop-up menu to set whether the camera is oriented towards the target
at every frame (Orient to Current) or oriented towards the target at its final position (Orient
to Final).
Position Transition Time:
A slider to set how long it takes the camera to reach the
framing position, measured as a percentage of the behavior’s duration.
Rotation Transition Time:
A slider to set how long it takes the camera to reach the
framing orientation, measured as a percentage of the behavior’s duration.
Transition:
A pop-up menu listing choices for the speed of the transition. Choices include
Constant, Ease In, Ease Out, Ease Both, Accelerate, or Decelerate.
Ease Out Time:
A slider to set the percentage of the behavior’s duration when the ease-out
effect starts. The ease out ramps down the behavior’s effect until the end of the behavior.
Ease Out Curve:
A slider that sets the rate of the ease out.
HUD Controls
The HUD contains a subset of the controls in the Inspector.
