Request body
9 properties · 1 required · 0 $defs| property | type | description | constraints |
|---|---|---|---|
| prompt* | string | Direction for the visuals, spoken dialogue, sounds, and on-screen text. Structure it with `[VISUAL]`, `[SPEECH]`, `[SOUNDS]`, and `[TEXT]` sections for best results. English is the validated language. | length ≥ 1 · length ≤ 5000 |
| duration | number | Length of the generated video in seconds at 24 FPS, rounded by the model to the nearest legal frame count (5 s -> 121 frames, 10 s -> 241, 15 s -> 361). With `audio_url`, the first `duration` seconds of the audio are used; shorter audio is padded with silence. | 1 ≤ n ≤ 20 · default: 10 |
| enable_safety_checker | boolean | Authorized callers may set false to request relaxed screening. | default: true |
| manifest_disclosure | boolean | Add a visible `AI-generated` disclosure label to the video. Invisible C2PA metadata and watermarking are always applied. | default: false |
| image_url | string | Optional reference image to animate. Guides identity, composition, and appearance; the output follows this image's aspect ratio. | nullable |
| aspect_ratio | enum | Frame ratio. `auto` follows the reference image's own ratio, and is landscape (16:9) when there is no image. A named ratio renders that ratio; with an image it centre-crops the image to it. | auto | 16:9 | 9:16 | 1:1 | 4:3 | 3:4 · default: "auto" |
| negative_prompt | string | Content or artifacts to avoid in the generated video. | default: "" |
| audio_url | string | Optional driving audio (narration, dialogue, or a soundtrack). When provided it is preserved in the output instead of generated speech. | nullable |
| resolution | enum | Delivery tier. `2k` is 2016 px on the long edge for 16:9 and 9:16, and the 1440p row for 1:1, 4:3 and 3:4. | 720p | 1080p | 2k · default: "720p" |
