In film or video production, what is a script?

A script serves as the fundamental backbone of any film or video production. It is a comprehensive written text that details not only the dialogue spoken by characters but also outlines the actions that occur and the specific scenes that are to be filmed. This format provides a clear and organized structure for the entire production process, allowing directors, actors, and crew members to understand their roles and responsibilities.

The correct answer reflects the essence of what a script is – it communicates the narrative to be visually represented and guides the entire production team through the filming process. A well-crafted script is essential for ensuring that everyone involved is aligned with the story being told and the intended performances.

In contrast, other options do not capture the full scope of a script's purpose. For instance, while a visual representation of the final film or a document focused on costume design may be crucial elements of production, they do not encompass the narrative and structural details found in a script. Similarly, a guideline for filming locations and timings can assist with logistics but lacks the narrative content that a script provides. Thus, a script's role as a detailed written text is vital in film and video production.
