Add a shape mask to a video effect in Final Cut Pro
You can define the area of a video effect, including a color correction, using the powerful
shape-masking tool.
In the example below, you can apply an effect (such as Gaussian) to everything outside or
inside the mask shape that you define.
You can add multiple masks to define multiple areas, and you can also animate the shapes
so that they follow a moving object, or follow an area while a camera pans.
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. If the Video inspector isn’t already open, 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.
5. Click the Video button at the top of the inspector.
