Time code synchronization

To synchronize the built-in time code generator of video equipment such as a VTR to an external time code.

Turbo gain

Video amplifier gain boosted from 30 dB to 36 or 42 dB by combining blocks of 2 or 4 adjacent pixels of the CCD.

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.

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

A

Amount of amplification for video signals, expressed in decibels (dB).

VITC

 

 

Vertical Interval Time Code. A time code recorded on video tape in two

 

horizontal lines during each vertical blanking period of a video signal.

 

Unlike LTC, VITC is recorded in the same tracks as the video

 

information, so they can be read even while the tape is not moving. See

 

also Time code and LTC.

 

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.
