Final answer:
All master clips in a film project have to be captured on the master frame chosen by the director during post-production.
Step-by-step explanation:
In film production, all master clips have to be captured on a specific frame called the master frame. This frame is selected by the director during the post-production phase, where they go through all the shots and choose the ones that best fit their vision for the storytelling. The master frame is important because it sets the visual and narrative tone for the entire film.
