API README
Seedance 2.5 Image to Video
Seedance 2.5 image-to-video: image becomes the first frame and the prompt directs motion, camera, and sound. Add end_image to set the final frame.
Fields
| Field | Type | Default | Notes |
|---|---|---|---|
prompt | string, required | — | Up to 50,000 characters. |
image | image URL, required | — | First frame. JPEG, PNG, or WebP URL. |
end_image | image URL | — | Optional last frame. |
duration | auto / 4 / 5 / 6 / 7 / 8 / 9 / 10 / 11 / 12 / 13 / 14 / 15 / 16 / 17 / 18 / 19 / 20 / 21 / 22 / 23 / 24 / 25 / 26 / 27 / 28 / 29 / 30 | 5 | Output length in seconds (4–30), or auto to let the model choose. |
resolution | 480p / 720p / 1080p | 720p | Sets the per-second rate. |
generate_audio | boolean | true | Native dialogue, music, and effects. Same price on or off. |
seed | integer -1–4294967295 | random | Fix it to compare prompt changes; -1 is random. |
Billing
You pay for output seconds: $0.18 at 480p, $0.36 at 720p, $0.90 at 1080p. Audio is included. With duration: "auto" the quote assumes 30 seconds and the final charge uses the generated length.
| Output | 480p | 720p | 1080p |
|---|---|---|---|
| 4s | $0.72 | $1.44 | $3.60 |
| 5s (default) | $0.90 | $1.80 | $4.50 |
| 10s | $1.80 | $3.60 | $9.00 |
| 15s | $2.70 | $5.40 | $13.50 |
| 30s | $5.40 | $10.80 | $27.00 |
Failed runs are not charged.
Prompting
- Describe what moves and how the camera behaves, not what is already visible.
- With two frames, describe the transition between them.
Limits
- Clips are 4–30 seconds.
Draft mode
Draft mode is two calls to this same model:
- Draft: add
"draft": true. The output is a 480p preview billed at the 480p rate, andoutputs[0].draft_ididentifies it. - Final: send
{"draft_id": "<outputs[0].draft_id>"}(optionallywatermark). The same shot is rendered at 1080p and billed at the 1080p output rate for the actual output length.
The final reuses the draft's prompt, media, duration, aspect ratio, seed and audio setting; those fields are ignored when draft_id is set. A draft can be finalized within 7 days, only with the model that created it.
{"prompt": "Slow 360-degree orbit around the subject.", "image": "https://example.com/first-frame.png", "duration": 5, "draft": true}
{"draft_id": "<outputs[0].draft_id from the draft>"}
