Editing Project Properties
Even though every project starts out with a preset group of project properties, you can
change them at any time, even after you’ve added objects.
To edit the properties of an existing project:
1 Choose Edit > Project Properties (or press Command-J).
2 In the Project Properties dialog, change any necessary parameters, then click OK.
For more information on the parameters available in the Project Properties dialog, see
“
General Tab of the Project Properties Dialog ” on page 184 and “ Render Settings Tab of
the Project Properties Dialog ” on page 187.
Most changes made to a project’s properties are fairly transparent and have no visual
effect on the project itself. The main exception is a change made to the project’s
frame size.
Changing the Frame Size of a Project
When you change the frame size of a project (in Project Properties) that already has
objects within it, you essentially change the size of the Canvas. This adds to, or reduces,
the amount of room available to lay out the objects in your project.
It’s important to understand that changing the size of the Canvas in no way changes
the size or position of any objects already placed within it. Furthermore, since the
coordinate system used by Motion uses 0, 0 as the center of the frame, all objects
remain arranged in their current positions relative to the center of the frame as the
edge of the frame shrinks toward the center. This may result in objects being cut off as
the frame shrinks past their edges. In the following example, a project with a frame size
of 720 x 480 is reduced to 320 x 240.
