End: A dial that sets the camera’s final angle relative to its Start parameter value.
Speed: A pop-up menu that sets the type of interpolation used for the rotation. The value
can be set to Constant, Ease In, Ease Out, Ease Both, Accelerate, or Decelerate.
Axis: A pop-up menu that sets the axis around which the sweep occurs. Value can be
set to Tilt X, Swivel Y, or Roll Z.
HUD Controls
The HUD contains the same controls as the Inspector.
Zoom In/Out
Animates the camera’s Angle of View parameter.
Parameters in the Inspector
Zoom: A slider that sets a proportional value to modify the camera’s Angle of View
parameter. For more information about the Angle of View parameter, see Camera Controls.
Speed: A pop-up menu that sets the type of interpolation for the movement. The value
can be set to Constant, Ease In, Ease Out, Ease Both, Accelerate, or Decelerate.
HUD Controls
The HUD contains the same controls as the Inspector.
Zoom Layer
Moves a camera to the position of a target object’s anchor point. When the camera reaches
the object’s anchor point, the angle of view changes while offsetting the camera’s position
based on the Zoom parameter. (This parameter is set to 0 by default so no animation of
the Angle of View occurs.)
This behavior also allows you to animate the camera’s Angle of View during the camera’s
movement, based on the behavior’s Transition value. For more information about the
Angle of View parameter, see Camera Controls.
Parameters in the Inspector
Object: An image well to set the target of the camera’s movement. Drag an object from
the Layers list into the well.
Transition: A slider that determines how far into the behavior the camera stops moving
and the camera’s Angle of View parameter begins to animate instead.
If Transition is set to 50% in a Zoom Layer behavior that has a length of 300 frames, the
camera move takes 150 frames to arrive at the position of the target object and then
stops moving for the duration of the behavior, and the camera’s Angle of View parameter
animates over the rest of the duration. If Transition is set to 100%, the camera move takes
the full 300 frames to arrive at the position of the target object, and the camera’s angle
of view does not animate. If the Zoom Layer behavior’s duration is 100 frames and
Transition is set to 50%, the camera move takes 50 frames to arrive at the position of the
target object.
