1092 Glossary
noise floor The background noise generated by audio equipment during recording,
which inadvertently becomes a part of the recording.
non-drop frame timecode Timecode in which frames are numbered sequentially
without dropping any frames 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. Compare
with 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. Compare with linear editing.
NTSC format The video standard defined by the National Television Standards
Committee, the organization that originally defined North American broadcast
standards. NTSC video has a specifically limited color gamut, is interlaced, has a frame
size of 720 x 486 pixels (720 x 480 for DV), and a frame rate of 29.97 fps. Compare with
PAL format.
NTSC legal The range of color that can be broadcast free of distortion according to the
NTSC standards.
offline Clips whose media files are currently unavailable to your project. They appear in
the Browser with a red slash through them. Clips may be offline because media files
haven’t been captured yet or because they’ve been modified in some way. To view
these clips properly in your project you must recapture them or reconnect them to
their corresponding media files.
offline editing The process of editing a program at a lower resolution to save on
equipment costs or to conserve hard disk space. When the edit is finished, the material
can be recaptured at a higher quality.
opacity The level of a clip’s transparency.
ordered timecode break A nearly imperceptible gap in the timecode track of a tape
that breaks the continuous flow of timecode but doesn’t result in the timecode being
reset to 00:00:00:00. See also timecode.
outgoing clip The clip a transition segues from. For example, if Clip A dissolves to Clip
B, Clip A is the outgoing clip.
