Add a color mask to a video effect in Final Cut Pro
You can create a color mask to apply a video effect, including a color correction, to a
particular color in an image, or to exclude a color from the effect.
For example, you could use a color mask to mute a bright color in the background that
distracts attention from a shot’s main subject.
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. Add an effect to the timeline clip from the Effects browser.
Note: This includes the color correction effects, which you can apply from the Color
category of the Effects browser or from the Color inspector. See Add color corrections
in Final Cut Pro.
4. To open the Video inspector, choose Window > Show in Workspace > Inspector (or
press Command-4).
