Apply the chroma key effect
1. In the Final Cut Pro timeline, add the foreground clip (the chroma key clip with the color
you want to remove) to the primary storyline.
2. Drag the background clip (the clip you want to superimpose the chroma key clip over)
so that it’s connected below the foreground clip in the primary storyline.
For more information about connected clips, see Connect clips in Final Cut Pro.
3. Select the foreground clip in the timeline, then click the Effects button in the top-right
corner of the timeline (or press Command-5).
Tip: For best results, position the playhead at a point within the foreground clip that
shows the maximum amount of the color to be keyed.
4. In the Effects browser, select the Keyer effect.
Tip: Type “keyer” in the Effects browser search field to quickly find the Keyer effect.
5. Do one of the following:
• Drag the effect to the timeline foreground clip you want to apply the effect to.
• Double-click the effect thumbnail to apply the effect to the selected clip.
The Keyer effect analyzes the video to detect a green or blue dominant color and then
removes that color. If the resulting key isn’t right or you want to improve it, you can adjust
the chroma key effect.
