The text prompt for video generation. Supports Chinese and English, max 800 characters.
Additional Settings More
Customize your input with more control.
The aspect ratio of the generated image. Allowed values: 16:9, 9:16, 1:1, 4:3, 3:4.
URL of the audio to use as the background music. Must be publicly accessible.
Limit handling: If the audio duration exceeds the duration value (5 or 10 seconds),
the audio is truncated to the first 5 or 10 seconds, and the rest is discarded. If
the audio is shorter than the video, the remaining part of the video will be silent.
For example, if the audio is 3 seconds long and the video duration is 5 seconds, the
first 3 seconds of the output video will have sound, and the last 2 seconds will be silent.
- Format: WAV, MP3.
- Duration: 3 to 30 s.
- File size: Up to 15 MB.
Video resolution tier Allowed values: 480p, 720p, 1080p.
Duration of the generated video in seconds. Choose between 5 or 10 seconds. Allowed values: 5, 10.

|---|---|---|---|
prompt | string, required | — | Text instruction. |
aspect_ratio | 16:9 / 9:16 / 1:1 / 4:3 / 3:4 | 16:9 | Output frame shape. |
audio | audio URL | — | Optional WAV/MP3 URL that drives speech or rhythm. |

duration | 5 / 10 | 5 | Output length in seconds. |
seed | integer | random | Fix it to compare prompt changes. |
Billing
You pay for output seconds: $0.05 at 480p, $0.10 at 720p, and $0.15 at 1080p.
| Output | 480p | 720p | 1080p |
|---|---|---|---|

Prompting
- Describe the shot in order: subject, action, setting, camera move, light, and sound.
- Give camera timing explicitly, e.g. “holds for two seconds, then pushes in slowly”.
Limits
- Durations are 5 or 10 seconds only.

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.
