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 |
|---|---|---|---|
| soft light | 35% | 18% | 1.98x |
Across all 5,926 prompts, the techniques used here appear at: tracking 41%, natural light 29%, slow motion 21%, soft light 18%.
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.
