Chapter 5 Working With Text 75
To fill the track contents with an image or movie:
1 Select a track that contains the text or object you want to fill with an image or movie.
2 Click the Attributes tab of the Inspector.
3 In the Matte pane, choose Movie or Image from the “Matte to” pop-up menu.
4 Locate the file in the Choose Movie or Image dialog, then click Open.
The track contents fill with the background movie or image.
Note: If you want to reveal a specific portion of the image or movie within your
foreground element, you may find that this matte option is not appropriate, since you
cannot adjust the relative position of the image and your foreground element. If this is
the case, you must use the Matte to Background option described above, which allows
you to position the two components independently.
