non-drop-frame Timecode method that uses the color TV frame rate of 29.97 fps. Non-drop-frame timecode is
preferred for nonbroadcast applications and most of low-end videotape formats. Compare to “ drop-frame ” on
page 301.
nonlinear editing Random-access editing of video and audio on a computer, enabling edits at any point in the
timeline. By contrast, traditional videotape editors are linear because they require editing video sequentially, from
beginning to end.
NTSC National Television Standards Committee. Standard for color TV transmission used in North America, Japan,
Central America, and some countries in South America. NTSC incorporates an interlaced display with 60 fields per
second, 29.97 frames per second (fps).
NTSC color bars The pattern of eight equal-width color bars used to check broadcast transmission paths, recording
quality, playback quality, and monitor alignment.
NTSC RGB Interlaced red, green, and blue video signals that meet NTSC standards and represent the primary colors of
an image.
O
offline editing Editing a rough cut using low-quality clips, and then producing the final cut with high-quality clips,
usually on a more sophisticated editing system than that used for developing the rough.
online editing Doing all editing (including the rough cut) on the same clips that will be used to produce the final cut.
P
PAL Phase alternating line. The TV standard used in most European and South American countries. PAL uses an
interlaced display with 50 fields per second, 25 frames per second.
PCI slot A connection slot for expansion cards found in most computers. Most video capture cards require a PCI slot.
peak file A cache file that contains the waveform image of an audio file. Peak files allow a program to open, save, and
redraw audio files more quickly because the program doesn’t have to reread the waveform data each time it opens or
displays an audio file. Peak files (*.pk) can be deleted without affecting the original audio files.
pixel An abbreviation for picture element, the smallest display element on a computer monitor—a point with a specific
color and intensity level. Graphics programs use square pixels. However, NTSC and PAL video pixels are rectangular,
so computer graphics displayed on a TV screen will be distorted (for example, a circle will appear as an oval) unless
the aspect ratio of the graphics is adjusted for video.
pixel shader In 3D graphics, a program that a GPU uses to render the lighting and color of individual pixels, creating
realistic-looking surfaces. (Not all GPUs support pixel shaders.) Pixel shaders are commonly used in creating graphics
for computer games.
plug-in A software module that can extend the features of a software application. In Adobe Premiere Elements, for
example, you can use VST plug-ins to add audio effects.
podcasting Delivering audio or video files to mobile devices via the web.
poster frame A single frame of a clip, selected as a thumbnail to indicate the clip’s contents.
preview files Files that store information about tracks and effects in a project. Preview files are created during the
rendering process and stored on the hard drive. They save time during the final export of a movie because the video
edition application can use the information in the preview files rather than render clips again.
printing to tape Recording a digital video file to videotape.
project preset A predefined set of values that can be used for project settings.
