Using Masks in Templates
You can use shapes and masks in any Final Cut template type.
In general, use of shapes should be limited to generator templates. Shapes are ideal
generator template elements because they can be scaled in Final Cut Pro X without
degradation. (However, too many shapes in a template can adversely impact performance
in Final Cut Pro.)
When you add a shape to a placeholder layer, the shape is converted to a mask. When a
template with a masked placeholder is applied to a clip in Final Cut Pro, the mask is
applied to the clip. Objects in the template outside the placeholder are not affected.
You can publish mask parameters (Roundness, Feather, and Mask Blend Mode, and so
on) so they are editable in Final Cut Pro. However, the onscreen mask controls in Motion
are not available in Final Cut Pro. To reposition a template mask in Final Cut Pro, publish
the mask’s transform parameters (located in the mask’s Properties Inspector). For more
information on publishing, see
Publishing Parameters in Templates
