In filmmaking, what does it mean to "dub" a movie?

Dubbing a movie refers to the process of replacing or adding sound to a film, primarily focusing on the dialogue. This can involve translating and recording the characters' lines into a different language, or altering the original audio to improve timing, clarity, or overall sound quality. The primary goal of dubbing is to make the film accessible to audiences who speak different languages or to enhance the viewer’s experience by improving audio quality.

In the context of the other choices, changing the plot involves rewriting the story, which is unrelated to dubbing; shortening its duration pertains to cutting scenes or content, which again does not fit the definition of dubbing; while editing scenes deals with rearranging or cutting footage to streamline the narrative but does not involve audio changes. Thus, the focus on sound and dialogue shows why dubbing is defined specifically by the addition or alteration of the soundtrack in a film.
