## Parameters

| Parameter         | Type    | Required | Default      | Description                                                                                                                        |
| ----------------- | ------- | -------- | ------------ | ---------------------------------------------------------------------------------------------------------------------------------- |
| `prompt`          | string  | yes      | -            | Text prompt describing the video (text-to-video) or the motion to apply to the source image (image-to-video).                      |
| `model_tier`      | enum    | no       | `"standard"` | standard: 720p, fastest. pro: 1080p, higher fidelity. 4k: 3840x2160, highest fidelity and cost. · Allowed: `standard`, `pro`, `4k` |
| `aspect_ratio`    | enum    | no       | `"16:9"`     | Aspect ratio for text-to-video. Image-to-video follows the source image. · Allowed: `16:9`, `9:16`, `1:1`                          |
| `duration`        | integer | no       | `5`          | Video length in seconds (3 to 15). · Range: 3 – 15                                                                                 |
| `sound`           | boolean | no       | true         | Generate native audio with the video. Standard and pro bill a higher rate with sound on; 4k includes audio.                        |
| `negative_prompt` | string  | no       | `""`         | What to avoid in the output.                                                                                                       |
| `image`           | string  | no       | -            | Source image URL for image-to-video. One image animates from that frame; two set the first and last frame.                         |

## Notes

Model tiers: standard renders 720p, pro renders 1080p, 4k renders 3840x2160. Durations run 3 to 15 seconds. Native audio is on by default; turning Sound off bills the lower rate on standard and pro, while 4K includes audio at one flat rate. Image-to-video accepts one or two images (first and last frame) and follows the source image size.
