MP3.

Builds on previous MPEG standards, adding support for streaming video and improved compression schemes. Often used for video

podcasting.

Refers to editing originally captured clips, both DV and HDV, at their original, uncompressed quality.

The range of grays, from black to white, that have no color. For neutral color areas, RGB values are equal.

Distortions of an audio or video signal, usually caused by interference.

The reduction of noise during recording or playback.

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.

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.

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).

The pattern of eight equal-width color bars used to check broadcast transmission paths, recording quality, playback quality, and

monitor alignment.

Interlaced red, green, and blue video signals that meet NTSC standards and represent the primary colors of an image.

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.

Doing all editing (including the rough cut) on the same clips that will be used to produce the final cut.

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.

A connection slot for expansion cards found in most computers. Most video capture cards require a PCI slot.

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.

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.

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.

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.

Delivering audio or video files to mobile devices via the web.
