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 eects you apply to your footage never aect the original source media
les. Clips represent your media, but they are not the media les themselves. The clips
in a project simply point to (link to) the source media les on your hard disk. When you
modify a clip, you are not modifying the media le, 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 les 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 o 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 dened by the National Television Standards
Committee, the organization that originally dened 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.
oine A post-production process in which raw footage is copied and edited without
aecting the original camera media (lm, tape, or le-based media). After a program
has been completed in the oine 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.
