Dolly behavior in Motion
The Dolly behavior moves the camera a specified distance along the camera’s Z axis.
After you apply this behavior, the Dolly section of the Behaviors Inspector contains the
following parameter controls:
• Distance: A slider to set the distance of the dolly movement.
• Speed: A pop-up menu to set the type of interpolation used for the movement. The
value can be set to Constant, Ease In, Ease Out, Ease Both, Accelerate, or Decelerate.
The HUD contains the same controls as the Inspector.
Focus behavior in Motion
The Focus behavior animates the camera’s Focus Offset parameter to focus on a target
object. For more information on camera focus settings, see Intro to depth of field in Motion.
Tip: Use this behavior to perform a rack-focus effect during a scene.
After you apply this behavior, the Focus section of the Behaviors Inspector contains the
following parameter controls:
• Target: An image well to specify the object upon which the camera will focus. Drag an
object from the Layers list into the well.
• Transition: A slider to set how long it takes for the camera to reach the focus position,
measured as a percentage of the behavior’s duration.
• Speed: A pop-up menu to set the type of interpolation used for the movement. Values
include Constant, Ease In, Ease Out, Ease Both, Accelerate, or Decelerate.
The HUD contains the same controls as the Inspector.
Framing behavior in Motion
The Framing behavior animates the camera along a path to position it in front of a selected
layer. You can control how the layer 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 handles to allow you to manipulate the path and ending position
in the canvas. For more information on using the Framing behavior’s handles, see Use
Framing behavior onscreen controls in Motion.
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 behavior is applied, 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.
