Glossary 441
video scopes Tools you can use to evaluate the color and brightness values of video
clips in the Viewer, Canvas, or Timeline. Video scopes display an analysis of the video
frame located at the current playhead position.
Video Scopes tab A tab in the Tool Bench that contains the Waveform Monitor,
Vectorscope, Parade scope, and Histogram.
video switcher A device with multiple video inputs that allow you to cut or transition
between several sources. Video switchers are commonly used in tape-to-tape editing
suites.
video track A track in the Timeline into which you can edit video clip items.
VITC Stands for vertical interval timecode. Timecode that is written into the video signal
on the source tapes as they’re being recorded. You can view this timecode as a series of
changing, flickering white dots and line segments in one of the scan lines above the
active picture on a monitor in underscan or pulse-cross modes. When viewed normally,
the line containing the timecode is off the top of the screen. Because it’s part of the
video signal, VITC timecode can’t be changed on your original tapes without also
replacing the video signal. Compare with LTC.
Voice Over tool Allows you to record audio in Final Cut Pro while simultaneously
playing back a specified section of a sequence from the Timeline. Audio can be
recorded using any Mac OS X Core Audio-compatible device, such as a USB audio
capture device, PCI audio card, or the built-in microphone on a DV camcorder.
VTR Abbreviation for videotape recorder. Generally refers to professional equipment
used for recording video from various sources.
VU meter Short for Volume Unit meter. An analog meter for monitoring audio levels.
WAVE The primary audio file format used by Windows-compatible computers. WAVE
files can be either 8- or 16-bit, and use sample rates from 8 to 48 kHz.
Waveform Monitor A window in Final Cut Pro that displays the relative levels of
brightness and saturation in the clip currently being examined. Spikes or drops in the
displayed waveforms make it easy to see where the hot spots or dark areas are in your
picture.
white balance To make adjustments to a video signal being recorded in order to
reproduce white as true white. For example, if the white in a shot is too yellow because
of incandescent lighting, white balancing adds enough blue to make the white appear
neutral.
white level An analog video signal’s amplitude for the lightest white in a picture,
represented by IRE units.
