A single frame of a commercial that summarises the core message is labelled as (A) gist (B) basic themes (C) canned copy (D) key frame Correct Ans: (D) Explanation: In the world of advertising, a key frame refers to a single visual or image that captures the core message of a commercial. It acts like the essence of the ad in one frame. Advertisers use key frames to summarize the most important idea they want the audience to remember. Therefore, it works as a quick visual cue that defines the brand’s message, tone, and intent. Let’s say an ad promotes a health drink. The key frame might show a fit, happy person holding the product with a tagline like “Energy that lasts all day.” This single frame reflects the product’s benefit, the target audience, and the brand emotion—all in one glance. Now, let's eliminate the incorrect options:(A) Gist refers to the general idea but doesn’t imply a visual representation.(B) Basic themes are overarching ideas behind a campaign, but they are broad and not specific to one visual moment.(C) Canned copy refers to pre-written or reusable ad content, often textual—not a single visual frame. The key frame holds special importance in ad production. It helps during the approval stage when clients or creative directors need to visualize the final message early. Also, during storyboarding, it offers a snapshot of the commercial’s highlight or climax. Production teams often build sets, camera angles, and even emotions around the key frame to ensure cohesiveness and clarity throughout the commercial. Furthermore, a well-designed key frame also works as a promotional material. Brands can use it for posters, thumbnails, print ads, or social media teasers—making it an extremely versatile creative tool. In conclusion, the key frame serves as a visual anchor that communicates the advertisement’s central message. That’s exactly why option (D), key frame, is the correct and most precise answer.
