Cameras
In 3D mode, anything you see in the Canvas represents the viewpoint of a camera,
either a default reference camera or a scene camera that you create. You can explicitly

Creating a Scene Camera
The scene cameras that you create are used for rendering output. Scene cameras
appear in the Canvas as wireframe camera icons and as objects in the Layers list and
Timeline.
To add a scene camera to a Motion project:
m Choose Object > New Camera (or press Command-Option-C).
A camera object is added to the Layers list, the Timeline, and the Canvas (represented
there by a wireframe icon). The 3D Transform tool in the Toolbar becomes active, the
Camera HUD appears (if it isn’t visible, press F7), and the Camera tab in the Inspector
becomes available.
Camera Controls
You can modify a scene camera’s properties via the Camera HUD or the Camera and
Properties tabs in the Inspector.
Parameters in the Inspector
There are six parameters in the Camera tab of the Inspector:
