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 mode. 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. See also
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, a 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 An audio file format based on the general-purpose RIFF format developed by
Microsoft and IBM. WAVE files contain “chunks” identified by a four-letter code. For
example, WAVE files store audio samples in a “data” chunk, and format information such
as sample rate is stored in an “fmt” chunk. WAVE files typically store uncompressed audio
using pulse-code modulation (PCM), but it is also possible to store compressed audio
samples.
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.
widescreen Any movie presentation that has an aspect ratio wider than 4:3. In movie
theaters, 1.85 is considered standard and 2.40 is considered widescreen. For video, 4:3 is
considered standard and 16:9 (which is almost the same aspect ratio as 1.85) is considered
widescreen. See also

window burn Visual timecode or keycode information superimposed onto video frames.
It usually appears on a strip at the bottom or top of the frame, providing timecode
information to the editor without obscuring important details of the picture.
