Ways to view masks in Final Cut Pro
You can display the precise area of a mask in the viewer as a black-and-white alpha
channel image or as a color image, showing the actual color contents of the mask.
Changing the viewing mode helps you see which areas of the image are being affected (by
a color correction, for example).
1. Add a clip to your Final Cut Pro project, then select the clip in the timeline.
2. Do one of the following:
• Add an effect to the clip, then add a mask to the effect.
Note: Effects you can mask in this way include color corrections.
• Add a color mask or a shape mask to the clip.
3. Position the playhead in the timeline so that the clip appears in the viewer.
4. If the Color inspector isn’t already shown, do one of the following:
• Choose Window > Go To > Color Inspector (or press Command-6).
• Click the Enhancements pop-up menu below the viewer and choose Show Color
Inspector.
5. In the inspector, click the View Masks button to show the mask in the viewer.
