## Input Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `mode` | enum | Yes | edit | edit changes what happens inside the clip and keeps its length. extend adds new footage before or after it. (Options: edit, extend) |
| `prompt` | string | Yes | - | The change you want. Do not write the trigger wording yourself — the server prefixes the canonical phrase for your mode. Tag extra materials as @Image1, @Video2, @Audio1 (the source clip is always @Video1). |
| `video_url` | url | Yes | - | The clip to edit or extend. Must be 4-30 seconds. Becomes @Video1. |
| `direction` | enum | No | forward | extend only: whether the new footage comes after the clip or before it. (Options: forward, backward) |
| `duration` | integer | No | -1 | extend only: length of the result in seconds (4-30), or -1 to let the model choose. Ignored in edit mode, where the provider requires -1 and matches the source length. (min: -1, max: 30) |
| `reference_images` | array | No | - | Up to 30 extra images, e.g. the face or product to paste into the shot. |
| `reference_videos` | array | No | - | Up to 9 extra clips alongside the source (10 videos total, 30s combined). |
| `reference_audios` | array | No | - | Up to 10 audio tracks, e.g. a voice to match. |
| `resolution` | enum | No | 720p | Output resolution. Seedance 2.5 supports 480p and 720p only. (Options: 480p, 720p) |
| `generate_audio` | boolean | No | true | Generate a native audio track. |
| `thinking` | boolean | No | false | Let the model reason about the prompt before generating. Costs no extra credits. Off by default. |
