Final answer:
Documentary films often have higher shooting ratios than commercial narrative films since their stories are largely discovered during postproduction.
Step-by-step explanation:
Documentary films often have higher shooting ratios than commercial narrative films since their stories are largely discovered during postproduction. Shooting ratio refers to the number of minutes shot compared to the number of minutes included in the final film.
In documentary filmmaking, filmmakers often shoot a large amount of footage to capture real-life events as they unfold. This gives them more material to work with during the editing process, where they discover and shape the story.
Commercial narrative films, on the other hand, follow a scripted story and have a more predetermined shooting plan, resulting in a lower shooting ratio. The scripts for these films are written in advance and the footage is more closely aligned with the planned scenes.
