Use ChatGPT to Develop a One-Line Story Idea Into a Full Prompt

A meta-prompting technique for when you have a vague idea but do not know how to write the full prompt yourself: feed a short concept into ChatGPT and ask it to develop the story prompt, not the story itself. Then copy the expanded result back into ChatGPT (or your generation tool) and run it. The seed prompt used here was: "Develop this prompt: Cook me a 2-minute heartbroken love story set in a sophisticated South Korean megacity. The first 3 seconds should glue the viewer instantly." The expanded output became the foundation for an entire story, including a cast reference image and a full continuity asset sheet (engagement ring, wine glasses, rain-streaked restaurant doors, a phone, a subway window, a luxury apartment interior, a job-offer email, a hospital referral envelope, a waterfront railing, an appointment card, a suitcase, an airport departure gate, and incoming text messages).
