Glossary 487
lower third A television industry term for a graphic placed in the lower area of the screen,
usually to convey details about subjects or products. A common use of lower thirds is to identify
individuals on the screen with their names and job titles.
luma A value describing the brightness of a video image. A luma channel is a grayscale image
showing the range of brightness across the whole clip.
luma key An effect used to key out pixels of a certain luma value (or a range of luma values),
creating a matte based on the brightest or darkest area of an image. Keying out luma values
works best when your clip has a large discrepancy in exposure between the areas that you want
to key out and the foreground images you want to preserve, such as a white title on a black
background. See also chroma key, matte.
Mail Mail is the email application that comes with OS X.
markers Markers flag a specific location in a clip with editing notes or other descriptive
information. You can also use markers for task management. Markers are classified as standard
markers (blue), chapter markers (orange), to-do items (red), or completed to-do items (green).
mask An image or clip used to define areas of transparency in another clip. Similar to an alpha
channel. The color correction tools can create masks based on a color you choose or a shape you
create. See also alpha channel.
matte Sometimes referred to as a holdout matte. An effect that uses information in one layer of
video to affect another layer. Mattes are useful when you want to use one clip to selectively hide
or reveal part of another; for example, you could use a round spotlight shape to reveal parts of
a video layer. Matte effects can be used by themselves to mask out areas of a clip or to create
alpha channel information for a clip in order to make a transparent border around the clip that
can be composited against other layers. See also alpha channel, compositing.
media A generic term for elements such as movies, sounds, and pictures.
media browsers Media that you import into events in Final Cut Pro is accessed from the
Libraries list and the Browser, but Final Cut Pro also includes a collection of media browsers you
can use to add clips to your project. The media browsers provide access to the effects, titles, and
transitions supplied with Final Cut Pro as well as to video, audio, and still-image files in other
applications on your computer. For example, you can use the Photos Browser to access video and
still-image files in the iPhoto and Aperture libraries. Other media browsers include the Effects,
Music and Sound, Transitions, Titles, Generators, and Themes Browsers. The media browsers
appear in the Media Browser pane in the lower-right corner of the Final Cut Pro main window.
media handle Additional media available before a clip start point or after a clip end point.
media stems Audio or video files that are usually exported separately for audio mixing or post-
production, or to match specifications when delivering files to broadcast networks. For example,
you may need to deliver a multitrack QuickTime file along with separate dialogue, music, and
effects stems.
mixing The process of adjusting the audio levels of all audio clips in an edited program,
including the production audio, music, sound effects, voiceovers, and additional background
ambience, to turn all of these sounds into a harmonious whole.
monochrome An image presented in shades of a single color, most often as the shades of gray
in a black-and-white image.
