How to Use
- Try it here first — Sign in and run the model in the playground above to check the output before you write code.
- Create an API key — Open Console → API Keys and create a key. The same key works for every model.
- Write your prompt — Describe the scene, action, camera movement, lighting and mood.
- Set optional parameters — Adjust the optional parameters listed above to control the output.
- Submit the job — Send POST /v1/jobs with the model ID seedance2.0. The response returns a job ID.
- Poll for the result — Call GET /v1/jobs/{job_id} every few seconds until the job finishes, then read the output URLs.
Writing Effective Prompts
Write the prompt like a shot list: the more you direct, the more the model delivers.
1. One-line summary
Open with subject, setting, action, style and camera in one sentence.
A cyclist rides along a foggy forest road at dawn, cinematic, slow side tracking shot.
2. Timeline for longer clips
Split the clip into timed beats, such as 0–3s and 3–6s, and give each beat one clear action.
3. Camera language
Use shot sizes (wide, medium, close-up) and moves (push in, pan, orbit, handheld) directly.
4. Consistency notes
End with what holds for the whole clip: lighting, color palette, mood and sound.
| Prompt | |
|---|---|
| Weak | a dog running |
| Strong | A golden retriever sprints across a wet beach at sunset, chasing a red ball. 0–2s: low tracking shot beside the dog, sand spraying. 2–5s: it catches the ball and turns to the camera, slow push in. Warm backlight, light sea spray, shallow depth of field, only the sound of waves. |

Best Use Cases
- Short-form social video — Create vertical and square clips for social feeds.
- Ads and product promos — Generate promotional clips and product scenes.
- Storyboards and previs — Turn scripts into motion previews for pitching and planning.
- Explainers and education — Visualize ideas, processes and stories.
- Music and mood clips — Produce atmospheric loops and visuals for music.
- Game and film concepts — Test scenes, camera moves and styles before production.
Pro Tips
- Test prompts at the shortest duration and lowest resolution, then scale up.
- Give each timed beat one clear action to avoid jump cuts.
- Use 16:9 for widescreen and 9:16 for vertical social video.
- Describe the camera movement explicitly; otherwise the model picks one for you.
- Poll the job status with a growing interval instead of hammering the endpoint.
