Prompt (original, unmodified)
Create a 15-second vertical 9:16 UGC-style phone case advertisement that feels authentic, premium, and social-media ready. A confident young woman in her mid-20s stands in a bright, modern apartment with soft natural daylight. She holds her smartphone toward the camera, showing a sleek premium phone case with a clean minimalist design. She smiles naturally and speaks directly to the camera as if recommending the case to a friend. Her appearance, outfit, phone, and phone case remain identical throughout the entire video. She speaks directly to the camera: “I’ve been using this case for a few weeks, and I honestly love it. It’s slim, feels amazing in my hand, and still gives my phone the protection I need. Plus, it looks so clean. Definitely one of my favorite phone accessories.” Storyboard: Scene 1: Close-up of the phone and case in her hand as she introduces it, rotating the phone slightly to reveal the back, edges, and camera protection. Scene 2: She holds the phone naturally in one hand, showing how slim the case looks while pressing the buttons and running her fingers across the smooth textured surface. Scene 3: She casually places the phone on a table and picks it back up, demonstrating the everyday practicality and secure grip of the case. Scene 4: She takes a quick mirror selfie, then turns the phone toward the camera to show how the case complements the phone’s original design. Scene 5: Final hero shot holding the phone beside her face with a clean, premium apartment background. She smiles confidently at the camera and says, “Definitely recommend.” The video should have realistic smartphone camera quality, natural handheld movement, genuine facial expressions, subtle autofocus adjustments, realistic lighting, smooth transitions, accurate lip sync, and a polished yet authentic UGC aesthetic. The phone and case must remain physically consistent throughout every shot. The case geometry, color, material, buttons, camera cutouts, edges, and proportions remain unchanged. The case stays sharply detailed and clearly visible whenever shown, with no warped branding, distorted geometry, or changing product design.

How this prompt compares
The techniques this prompt uses are more common in commercial prompts than in the library overall:
| Technique | In commercial | Library average | Lift |
|---|---|---|---|
| close-up | 62% | 40% | 1.56x |
Across all 5,926 prompts, the techniques used here appear at: close-up 40%, natural light 29%, handheld 24%.
The 15s duration is not arbitrary: 71% of the prompts in this library that state a duration ask for exactly 15 seconds — Seedance 2.0 accepts clips up to 15 seconds, so 15s is the model's ceiling and the most common choice.
