In video editing, what defines a Crawl title?

A Crawl title is characterized by its horizontal movement across the screen, typically from one side to the other, often used for credits or announcements. This style of title adds a dynamic element to a video, allowing text to be integrated with the visuals in an engaging way, while still being readable. The movement can be set to start from the left and move to the right or vice versa, creating a continuous flow that draws the viewer's attention.

In contrast, a title displayed without movement is static and does not have the same visual impact. Titles that scroll vertically or fade in and out serve different purposes and formats in visual communication, but they do not fit the specific definition of a Crawl title, which is primarily defined by its horizontal motion. Thus, the answer highlighting the horizontal movement accurately captures the essence of a Crawl title in video editing.
