Apple Final Cut Express HD - Manual (Page 1104)

1104 Glossary
Voice Over tool Allows you to record audio in Final Cut Express HD 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.
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 16:9.
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.
wipe A transition in which a geometric or grayscale gradient is used to transition
between two different clips.
wipe pattern One of several standard SMPTE wipe transitions recognized by EDLs.
Because the EDL format continues to reflect the simplicity of older systems, many
Final Cut Express HD transitions have no equivalent in a given EDL format. Therefore,
during the EDL export process, these new transitions are automatically mapped to the
closest approximate SMPTE standard wipe pattern.
Wireframe A view of the outline of a clip’s video frame. Clips in the Viewer and Canvas
can be viewed in wireframe mode.
x Refers to the x coordinate in Cartesian geometry. The x coordinate describes
horizontal placement in motion effects.
y Refers to the y coordinate in Cartesian geometry. The y coordinate describes vertical
placement in motion effects.
