Disclosure Devices, Continued
Crawl
A drum, called a crawl, rotated by hand or by motor to which you attach a
series of lettering on a long strip of paper, is known as a crawl device. The
lettering appears to scroll onto the screen and off again. Most often, the
lettering contrasts against a background and is superimposed over an image.
Many TV shows use a crawl device to display closing credits.
Figure 3-14 shows examples of crawl devices.
