Simulating Motion Blur on a Still Object
You can add motion blur to an object that has no axis movement, by adding a second axis to simulate the
motion.
To simulate motion blur on a still object:
1 From the View box, select Schematic.
2 From the Node bin, drag an Axis node to the schematic.
3 Press Shift and drag the original Axis node over the new Axis node.

Action 3D Cameras
The 3D camera is a full-featured animatable camera in Action that allows you to build 3D compositing
scenes, mixing 3D objects and stereo objects.
Typically, you work with the 3D camera to frame and animate the view to achieve the effect that you want.
You can also animate specific camera properties.
Use the 3D camera in Stereo mode to create three-dimensional renders with the illusion of a three-dimensional
depth-of-field. When rendering a stereoscopic scene, Action takes into account all of the stereoscopic camera
attributes. Action outputs two clips: one rendered for the left camera and one for the right camera. These
clips can then be viewed in stereo mode, used in other stereo clips, output to VTR, or composited by another
program.
Adding a 3D Camera
By default, a 3D camera exists in the Action scene when using stereo clips, or when Action has been set up
to work in stereo (you may need to pan in the schematic to see the camera node). You can add multiple 3D
cameras in order to change point-of-view or depth-of-field from one camera to another. You can add and
animate multiple cameras when creating compositions. You can also switch from one camera to another at
any point.
