Implementing a Chroma Keyed Clip

To chroma key a clip, do the following:

1.	Shoot your target clip (of persons or objects) against a green screen—a well lit, even blue or green surface, for example. This color should not be in the foreground object (a person’s tie, for example, shouldn’t be green when using a green screen).

2.	Shoot your background image or clip.

3.	Add the target clip to your project.

4.	Select a background color on the canvas for chroma key testing.

5.	Add the Chroma Key filter and set it up. See Applying the Chroma Key Filter.

6.	Test your clip by previewing it, and adjust chroma key settings as necessary. See Refining the Chroma Key Filter Settings

7.	If necessary, split your clips, add the chroma key filter and adjust it.

8.	When you’re satisfied with the chroma key, add your background image or clip to the project in the track immediately below the target clip.
