What is the purpose of a prompter in a video production?

A prompter, commonly known as a teleprompter, is designed specifically to display text for speakers to read during video production. This tool allows presenters or performers to maintain eye contact with the camera while delivering their lines smoothly, enhancing the overall delivery and engagement of the content. It provides a steady flow of information, which is especially important in live broadcasts or recordings where timing and precision are crucial.

The other options relate to different aspects of video production that do not align with the core function of a prompter. Editing video clips is a task typically managed by video editing software, controlling lighting effects involves the use of lighting equipment and technical skill in managing those settings, while audio levels are managed through sound mixing and audio equipment, not through a prompter. Thus, the unique purpose of a prompter clearly sets it apart from these other functions in video production.
