| Parameter | Type | Default | Range / values | Description |
|---|---|---|---|---|
| prompt | string | - | - | Scene description. |
| mode | enum | auto | auto, t2v, i2v | Auto detects image-to-video when an image is attached; otherwise text-to-video. |
| resolution | enum | 480p | 480p, 720p, 1080p | 480p is the fastest native tier. 1080p is upscaled and capped at 5 seconds. |
| aspect_ratio | enum | 16:9 | 16:9, 9:16, 1:1, 4:3, 3:4 | Output aspect ratio (1:1, 16:9, 9:16, 4:3, 3:2, etc.). |
| duration | number | 5 | 1 to 10 | Clip length in seconds. 1080p is capped at 5 seconds. |
| cfg_scale | number | 6 | 1 to 20 | Classifier-free guidance. Higher = follows prompt more strictly. |
| steps | number | 25 | 10 to 50 | Diffusion steps. More = higher fidelity, slower. |
| image | string | - | - | Reference image URL for i2v mode. |
| negative_prompt | string | - | - | What to avoid. |
