Glossary 469
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 Event 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.
outgoing clip The clip a transition segues from. For example, if Clip A dissolves to Clip B, Clip A is
the outgoing clip. See also incoming clip.
Out point See edit point.
overwrite edit In an overwrite edit, one or more source clips overwrite any clips in the primary
storyline or a selected storyline, starting at a range selection start point or at the skimmer or
playhead position. No clip items are rippled forward, so the duration of your project remains the
same. Overwriting is purely duration-based and works on range selections only, irrespective of
clip boundaries.
PAL format Acronym for Phase Alternating Line, a 25 fps (625 lines per frame) interlaced video
format used by many European countries. Digital PAL video has a frame size of 720 x 576. See
also NTSC format.
Photos Browser A media browser in Final Cut Pro that allows you to access your iPhoto and
Aperture photo libraries.
