For an example of how you might use shape masks set to the Intersect blend mode to
isolate one area of a color mask, see
Add shape masks to a color mask in Final Cut Pro.
Invert effect masks in Final Cut Pro
In most cases, you use the built-in masking capability of a video effect, including a color
correction, to limit the effect to a specific area or color. However, you can also invert your
mask to exclude a specific area or color from the effect.
1. Add a clip to your Final Cut Pro project, and select the clip in the timeline.
2. Position the playhead in the timeline so that your clip appears in the viewer.
3. If the Video inspector isn’t already shown, do one of the following:
• Choose Window > Show in Workspace > Inspector (or press Command-4).
• Click the Inspector button on the right side of the toolbar.
4. Click the Video button at the top of the inspector.
5. Add an effect to the timeline clip from the Effects browser.
6. Apply a shape mask or a color mask to the effect.
