Tip #190: Fast Green-Screen Keys in Motion
Four steps to better-looking keys.
The chroma-key filter, also called a “green-screen key,” in Motion and Final Cut Pro X is excellent at creating a clean key, generally without needing to touch any settings.
- Import the foreground shot that has the green background. (The smoother and brighter this background is lit, the better your key. Remember, we are replacing all the green pixels.)
- Import the new background shot you want to use in place of the original green and place it below the green-screen shot.
- Apply Filters > Keying > Keyer to the foreground clip.
- Apply Filters > Blur > Soft Focus to the background clip. Adjust the Amount setting so that you create the illusion of depth-of-field in the shot.
Generally, to make a key look really believable, you’ll also need to add some color correction to the foreground. But, in terms of creating the key, these are the steps you need to know.
