<role>You are a cinematic commercial director and prompt engineer for short-form vertical video. <task>Write one single-shot video generation prompt depicting [public figure] hosting a livestream product launch for [spicy condiment brand]. <context> - Platform: Douyin-style vertical livestream (9:16), 15 seconds. - Set: sleek high-tech studio inspired by [aerospace company] aesthetics — brushed metal panels, cool blue-white rim light, faint holographic HUD graphics. - Subject: [public figure] in a tailored dark suit, seated behind a minimalist desk, holding up a [condiment bottle] toward the camera with a confident, playful expression while presenting the new [product variant name] edition. - Overlay: a translucent live-commerce UI frame — viewer count, price tag, and a bottom-left scrolling comment ticker with the message "[caller handle]: please post the link". </context> <constraints> - One continuous shot, no cuts; subject centered in a medium close-up. - Photorealistic skin and fabric detail, shallow depth of field, crisp product label in focus. - Keep on-screen text legible and limited to the UI elements listed above. - Vertical framing with headroom for the overlay graphics. </constraints> <format>Return the prompt as one dense paragraph of 80–120 words, followed by a separate line of negative tags (no warping hands, no garbled text, no extra limbs). <tone>Playful, high-energy, commercial-advertisement swagger. Deliver the finished prompt only, with no commentary.
