MiniMax H3 Max Image to Video
MiniMax H3 Max image-to-video: animate a first frame, optionally toward a last frame, into a 5–15 second clip with native audio.
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. |
resolution | 480P / 768P | 768P | Sets the per-second rate. |
duration | integer 5–15 | 5 | Output length in seconds. |
prompt_expansion_mode | balanced / quality | balanced | balanced rewrites the prompt lightly; quality expands it more for richer detail. |
Billing
You pay for output seconds: $0.08 at 768P and $0.05 at 480P.
| Output | 768P | 480P |
|---|---|---|
| 5s (default) | $0.40 | $0.25 |
| 10s | $0.80 | $0.50 |

export SANDBASE_API_KEY="YOUR_API_KEY"Keep the key on your server. Do not expose it in browser code or commit it to a repository.
3. Queue
Submit a request
POST to /v1/run with this model ID and its inputs. The request example above includes submission and polling.
Fetch request status and result
Use the returned run ID to poll until the status is completed, failed or timeout. Read output only after completed.
curl "https://api.sandbase.ai/v1/run/$RUN_ID" \

Hosted files
Pass a publicly accessible file URL in the model’s image, video or audio field. Supported formats and limits are shown beside each Playground input.
Uploading images
Use the upload or replace control on supported image fields in the Playground. Video URL fields accept a hosted driving video; they do not imply video-upload support.
