Composite effects over a background
Often, Transform, Trim, and Distort effects result in the image being less than full size, with
the empty areas filled with black. You can replace the black with a background by placing
the transformed clip over a background clip (also known as compositing).
In Final Cut Pro, do one of the following:
• Add a clip to the timeline as a connected clip, then add the effect to that clip.
This places the clip above the primary storyline clip, which automatically becomes the
effect’s background.
• If the clip is already in the primary storyline, drag it above the primary storyline,
positioning it over the clip you want to be the background.
The result is a composited image.
For more information about working with connected clips, see Add storylines in
Final Cut Pro. For more information about compositing clips, see Intro to compositing in
Final Cut Pro.
