A bright vertical line that appears on the screen when shooting a very
bright object with a CCD camera. Also called smear.
Video gain

VITC

tracks as the video information, so they can be read with editing
recorder. 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.
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.
This is called white shading.
Zebra pattern
In a video camera, striped patterns that appear in the viewfinder screen to
indicate areas of the image where the video level is approximately 70%
and 100%. Used to confirm the video level of the subject. If a zebra
pattern appears on the skin when the subject 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).
