Playground
Input
The text prompt describing the desired motion and action for the video.
PNG, JPEG, WebP, or GIF · 20 MiB maximum
The URL of the starting frame image to animate. Supported formats: JPEG, PNG, WebP. Max 30 MB.
This field is required.
Additional Settings More
Customize your input with more control.
PNG, JPEG, WebP, or GIF · 20 MiB maximum
The URL of the image to use as the last frame of the video. When provided, the generated video will transition from the starting image to this ending image. Supported formats: JPEG, PNG, WebP. Max 30 MB.
Video resolution - 480p for faster generation, 720p for balance. Allowed values: 480p, 720p.
Output duration in seconds (4-15), or `auto` to let the model pick a length from the prompt and inputs. `auto` is pre-authorized at 15 seconds and billed on the actual output length. Allowed values: auto, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15.
Whether to generate synchronized audio for the video, including sound effects, ambient sounds, and lip-synced speech. The cost of video generation is the same regardless of whether audio is generated or not.
Output aspect ratio. Omit to match the input image. Allowed values: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16.

Seedance 2.0 Mini Image to Video
Seedance 2.0 Mini 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 | — | Text instruction. |
image | image URL, required | — | First frame. JPEG, PNG, or WebP URL. |
end_image | image URL | — | Optional last frame. |
resolution | 480p / 720p | 720p | Sets the per-second rate. |
duration | auto / 4 / 5 / 6 / 7 / 8 / 9 / 10 / 11 / 12 / 13 / 14 / 15 | 5 | Output length in seconds (4–15), or auto to let the model choose. |
generate_audio | boolean | true | Native dialogue, music, and effects. Same price on or off. |
aspect_ratio | 21:9 / 16:9 / 3:2 / 4:3 / 5:4 / 1:1 / 4:5 / 3:4 / 2:3 / 9:16 | — | Output frame shape. |
seed | integer -1–4294967295 | random | Fix it to compare prompt changes; -1 is random. |
Billing
You pay for output seconds: $0.06 at 480p, $0.12 at 720p. Audio is included. With duration: "auto" the quote assumes 15 seconds and the final charge uses the generated length.
| Output | 480p | 720p |
|---|---|---|
| 4s | $0.24 | $0.48 |
| 5s (default) | $0.30 | $0.60 |
| 10s | $0.60 | $1.20 |
| 15s | $0.90 | $1.80 |
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 4–15 seconds.

Create a SandBase API key and set it in your server environment. All requests use Bearer authentication.
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" \
-H "Authorization: Bearer $SANDBASE_API_KEY"4. Files
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.
