Parameters 8
| Name | Type | Default | Allowed | Description |
|---|---|---|---|---|
| promptrequired | string | Cinematic drone shot gliding through misty pine mountains at sunrise, god rays breaking through the fog, birdsong and gentle wind in the audio, photorealistic, highly detailed. | — | Describe the scene, subjects, camera moves and sound design. Supports bracketed timecodes like [0-3s] ... [3-6s], and <IMAGE_REF_0>, <IMAGE_REF_1>, ... to bind reference images. |
| first_frame | string | — | one image url | The video starts exactly from this image. |
| last_frame | string | — | one image url | Optional ending frame. With First Frame set, the model interpolates smoothly between the two. |
| reference_images | string[] | — | up to 10 image urls | 1-10 reference images. Subjects/styles are extracted and embedded into a new scene (not used as literal frames). Bind them in the prompt with <IMAGE_REF_0>, <IMAGE_REF_1>, ... Cannot be combined with First/Last Frame. |
| duration | integer | 5 | 3–10 | Video length in seconds (3-10). Billed per second of output video. |
| resolution | enum | 720p | 360p · 720p · 1080p · 4k | Output resolution. 360p is a draft tier (~1/3 the price, ~2x faster); 1080p costs 1.5x and 4k 3x the 720p rate per second. |
| aspect_ratio | enum | 16:9 | 16:9 · 9:16 | 16:9 landscape or 9:16 vertical. |
| seed | integer | -1 | -1–999999999999999 | Seed for reproducible generation. -1 for random. |
File inputs (first_frame: one image url · last_frame: one image url · reference_images: up to 10 image urls) take URLs. Upload the raw file to POST /v1/uploads with its own Content-Type and pass the url it returns. Inputs are kept 90 days.
