How do credits appear when they run up a screen?

Credits that appear when they run up a screen are referred to as a roll. This technique involves displaying text that moves vertically from the bottom to the top of the screen, typically used at the end of films or videos to acknowledge the people involved in the production. The rolling effect allows the audience to read the names in a continuous flow, creating a dynamic visual experience that is both informative and engaging.

The term “scroll” often describes text moving horizontally across the screen, which is different from the vertical movement seen in credits. "Fade" refers to a gradual transition in visibility, rather than a movement upward or downward, while "slide" typically describes a horizontal movement as well. Thus, the term roll specifically captures the essence of how credits are conventionally presented in film and video production.
