The sets of alternating horizontal lines that create an interlaced image on a TV screen. A complete TV frame consists of two fields: The
odd-numbered lines of field one are interlaced with the even-numbered lines of field two. See also interlacing.
The final video production, assembled from high-quality clips, and ready for export to the selected delivery media. Compare to rough cut.
The Apple® Computer trade name for IEEE 1394.
Frames per second; the standard for measuring the rate of video playback. At 15 fps and lower, the human eye can detect individual frames,
causing video to appear jerky.
A single still image in a sequence of images that, when displayed in rapid succession, creates the illusion of motion. The more frames per
second (fps), the smoother the motion appears.
The number of frames per second displayed during playback.
See fps.
The number of audio cycles per second, expressed in hertz (Hz). Frequency determines the pitch of a sound.
The range of color or brightness values allowed for a video signal. Values that exceed the gamut may cause distortion.
The series of visual tones that range from true black to true white. In video applications, grayscale is usually expressed in 10 steps.
Graphics processing unit. A microprocessor with built-in capabilities for handling 3D graphics more efficiently than a CPU (central processing
unit).
High Definition TV. A broadcast format that allows for a higher resolution signal than the traditional formats, NTSC, PAL, and SECAM.
High Definition Video. The format used to record HDTV-quality data with video camcorders.
The distinction between colors (for example, red, yellow, and blue). White, black, and gray tones are not considered hues.
The interface standard that enables direct transfer of DV between devices, such as a DV camcorder and a computer. IEEE 1394 also
describes the cables and connectors utilizing this standard. Also called FireWire or i.LINK. See also USB.
Sony® trade name for IEEE 1394.
Also referred to as electronic image stabilizer. A technique used to remove the movement caused by camera shake.
A compression scheme, such as MPEG, that reduces the amount of video information by storing only the differences
between a frame and those preceding it.
A system developed for early TV and still in use in standard TV displays. An electron gun illuminates the phosphors coating the inside
of the screen, first drawing the even, and then drawing the odd horizontal lines across the screen. By the time the even lines are dimming, the odd
lines are illuminated. We perceive these interlaced fields as complete pictures.
A method for establishing new data points between known data points.
An edit in which the audio starts before the video, giving the video a dramatic introduction. Also known as an audio lead.
Joint Photographic Experts Group. Also, a file format defined by that group for compressing still images. Because video is a sequence of
still images, JPEG compression can be used to compress video. See also MJPEG.
