Seedance 2.5 Audio Prompting Guide — Dialogue, Ambience & SFX
How to structure audio direction for Seedance 2.5: dialogue, ambience, sound effects and audiovisual continuity, with model-specific prompt examples.
Audio direction structure
- Dialogue: who speaks, delivery and timing.
- Ambience: persistent environmental sound bed.
- SFX: sounds tied to visible actions.
- Music: mood and intensity rather than copyrighted song imitation.
- Continuity: avoid abrupt audio resets between connected beats.
Example
Visual: 0–2s: low side shot of a black sports car idling in neon rain. 2–6s: car accelerates; camera tracks beside it, realistic spray and stable reflections. 6–8s: camera eases back as the car crosses the intersection. Keep one continuous direction of travel. Audio: steady rain ambience, low city traffic bed, realistic tire spray synchronized to wheel motion, no narration, no music unless explicitly requested.
GenVideoKit tracks Native audio as a capability for Seedance 2.5 in the current model catalog. Exact audio modes and provider behavior can change; verify delivery requirements in the provider interface or API documentation.
