Apple Final Cut Pro X (10.1.2) - Manual (Page 488)

Glossary 488
MP3 Refers to the MPEG-1 or MPEG-2 Audio Layer 3 compression standard and file format. Like
AAC, MP3 uses perceptual audio coding and psychoacoustic compression to remove superfluous
information that the human ear doesn’t hear.
MPEG (Moving Picture Experts Group) A group of compression standards for video and audio,
which includes MPEG-1, MPEG-2, and MPEG-4.
multicam clip A set of clips grouped together and synchronized by a common sync point. You
can use multicam clips to edit footage from multicamera shoots or other synchronized footage
in real time. While the active angle plays in the Viewer, you can also view all angles playing
simultaneously in the Angle Viewer and easily cut and switch between them.
Music and Sound Browser A media browser in Final Cut Pro that allows you to access your
iTunes content as well as sound effects and loops from Final Cut Pro and iLife.
nested sequence See compound clip.
NLE Short for nonlinear editor. See also nonlinear editing.
nondestructive editing No matter how you edit clips in Final Cut Pro, the underlying media is
never touched. This is known as nondestructive editing, because all of the changes and effects you
apply to your footage never affect the original source media files. Clips represent your media,
but they are not the media files themselves. The clips in a project simply point to (link to) the
source media files on your hard disk. When you modify a clip, you are not modifying the media
file, just the clip’s information in the project. Trimmed or deleted pieces of clips are removed from
your project only, not from the source clips in your library or from the source media files on your
hard disk.
non-drop frame timecode Timecode in which frames are numbered sequentially and no
timecode numbers are dropped from the count. When discussing NTSC video, the video frame
rate is actually 29.97 fps, and non-drop frame timecode is off by 3 seconds and 18 frames per
hour in comparison to actual elapsed time. See also drop frame timecode.
non-interlaced video The standard representation of images on a computer. Also referred to as
progressive scan. The monitor displays the image by drawing lines, one after another, from top
to bottom.
nonlinear editing A video editing method in which edits within a program can be changed
at any time without having to re-create the entire program. When you use a nonlinear editing
application to edit a program, all footage used is stored on a hard disk rather than on tape. This
allows random access to all video, audio, and images as you edit. See also linear editing.
NTSC format The video standard defined by the National Television Standards Committee, the
organization that originally defined North American broadcast standards. Analog NTSC video has
525 interlaced lines per frame, a frame rate of 29.97 fps, and a limited color gamut. Digital NTSC
video has a frame size of 720 x 486 pixels (720 x 480 for DV and DVD), and a frame rate of 29.97
fps. See also PAL format.
offline editing A post-production process in which raw footage is copied and edited without
affecting the original camera media (film, tape, or file-based media). After a program has been
completed in the offline edit (typically using proxy media at a lower resolution), an online edit is
performed to re-create the edit using the original media.
opacity The level of a clip’s transparency.
67% resize factor
