Glossary of terms
T
TBC See time base corrector.
temporal redundancy reduction See inter-
frame compression.
texture mapping
A display technique where
bitmaps (textures) are placed (mapped) onto 3D
surfaces to make objects look more realistic.
tile A transition in which one image is gradually
replaced by another image that appears part-by-
part in successive squares. The squares follow a
given pattern until the entire screen is filled with
the new image.
time base corrector (TBC)
An electronic
device that, when connected to the output of a
VTR, corrects the stability and timing of the
VTR’s playback video. This is achieved by
stripping the unstable horizontal and vertical sync
pulses from the video signal, and replacing them
with new, clean sync pulses.
time code A sequential code number assigned
to successive video frames on tape. Each frame has
its own time code, which is electronically encoded
on the tape in the form
hours:minutes:seconds:frames.
See also drop-
frame time code, LTC, and VITC.
timeline The graphical representation
(normally a horizontal line) of a video sequence. It
is usually divided into
hours:minutes:seconds:frames, and is used to
position video, audio, graphics, and video effects
that make up the sequence.
tint An effect that replaces the chrominance
information of an image with a single color, but
keeps the luminance levels of the image intact. The
result is an image formed with shades of only one
color. This is useful for simulating “old-time”
sepia images.
transform settings Settings that let you
change the position, size, and rotation of a clip in
the Matrox realtime plug-in. Transform settings
can be applied on the x, y, and z axes of a clip.
traveling matte effect
See mask effect.
U
Uncompressed-quality video Video that has
the same image quality as uncompressed video,
but has been compressed using mathematically
lossless compression to optimize storage space.
Also called lossless video.
V
VCD Video CD. A standard for storing video
and audio on a CD that provides slightly better
video quality than standard VHS. Video is
compressed using MPEG-1 at 1100 Kbps, and
audio is compressed as MPEG-1, layer II, at 224
Kbps. A VCD can hold about 60 minutes of
material. Video CDs can play back on most DVD
set-top players.
See also SVCD.
Video window
See DVE.
VITC Vertical Interval Time Code. Time code
that is encoded onto the vertical blanking interval
of a video signal. VITC can be read by a VTR
whenever an image is displayed, but not usually
during high-speed operation.
See also LTC.
Voice over Narration added to a video segment
and mixed in louder than the original background
sounds.
W
WAV An audio data file format developed by
Microsoft and IBM. This format is the standard for
Windows and can be played by most applications
that can support sound.
wipe
A transition in which one image is
gradually replaced by another image that is
revealed in a given pattern. For example, the
second image could be revealed from the top of the
screen downwards until it fills the entire screen.
See also organic wipe.
