How this prompt compares
The techniques this prompt uses are more common in music video prompts than in the library overall:
| Technique | In music video | Library average | Lift |
|---|---|---|---|
| match cut | 8% | 2% | 4.01x |
Across all 5,926 prompts, the techniques used here appear at: tracking 41%, close-up 40%, match cut 2%.
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.
