• Intersect: Applies the effect to any area inside the mask shape that overlaps with
other masks set to either Add or Intersect.
Note: At any time, you can invert all masks for a given effect. See Invert effect masks in
Final Cut Pro.
Reorder masks
The order in which you apply shape and color masks can affect the final output. The Add,
Subtract, and Intersect modes operate sequentially, starting at the top of the mask list in
the Video inspector. By default, new shape masks appear at the top of the list in Add mode,
and new color masks appear at the bottom of the list in Intersect mode. You can reorder
masks to achieve the effect you want.
1. To apply two or more masks to an effect in Final Cut Pro, follow steps 1 through 6 in
Add, subtract, and intersect masks, above.
The masks are listed below the effect name in the Video inspector.
2. To change the mask order, drag masks up or down in the list.
