UMID
Unique Material Identifier. A 
standard (SMPTE 330M) for video 
and audio metadata. The Basic 
section of a UMID contains a 
globally unique number and a 
material number for the identification 
of recorded material. An optional 
section called the “Source Pack” 
contains information such as the time 
and location of recording. A UMID 
with the Basic section only is called a 
Basic UMID. A UMID with the 
Source Pack is called an Extended 
UMID.
User bits
A total of 32 bits are provided in the 
time code which the user can use to 
record such information as date, 
scene number, or reel number on 
video tape. Also called user’s bits.
VBS
A composite signal consisting of 
video signal, burst signal and sync 
signal.
Vertical smear
A bright vertical line which appears 
on the screen when shooting a very 
bright object with a CCD camera. 
Also called smear.
Video gain
Amount of amplification for video 
signals, expressed in decibels (dB).
VITC
Vertical Interval Time Code. A time 
code recorded in two horizontal lines 
during each vertical blanking period 
of a video signal.
White balance adjustment
In the light of a particular color 
temperature, to adjust the white 
levels of the R, G, and B channels of 
a color video camera so that any 
white object shot in that light is 
reproduced as a truly white image. 
See also Color temperature.
White shading
When shooting a white object, the 
upper and lower portions of the 
screen may appear magenta or green 
while the central portion appears 
white, depending on the performance 
of the camera lens. This is called 
white shading.
Zebra pattern
In a video camera, striped patterns 
which appear in the viewfinder 
screen to indicate areas of the image 
where the video level is higher than a 
certain value. If a zebra pattern 
appears on the skin when the object is 
a human being, that is a correct 
exposure.
Zoom
To gradually change the field of view 
of a camera lens from wide to narrow 
angle (zoom in) or narrow to wide 
angle (zoom out).
