## README

### Wan 2.6 Flash Reference to Video

The fast, lower-cost Wan 2.6 reference tier. Cast characters from reference images or videos into a new scene for quick iterations; audio generation and multi-shot cuts are on by default.

#### Fields

| Field | Type | Default | Notes |
|---|---|---|---|
| `prompt` | string, required | — | Text instruction. |
| `images` | image URL[] | — | Reference images, Image 1, Image 2, … |
| `videos` | video URL[] | — | Reference clips, Video 1, Video 2, … |
| `resolution` | `720p` / `1080p` | `720p` | Sets the per-second rate. |
| `duration` | 5 / 10 | 5 | Output length in seconds. |
| `multi_shots` | boolean | true | Let the model cut between several shots. |
| `aspect_ratio` | `16:9` / `9:16` / `1:1` / `4:3` / `3:4` | `16:9` | Output frame shape. |
| `seed` | integer | random | Fix it to compare prompt changes. |
| `generate_audio` | boolean | true | Generate a synchronized audio track; turning it off halves the rate. |

#### Billing

With audio you pay $0.10 per output second at 720p and $0.15 at 1080p; silent output costs half. When you send reference `videos`, 5 seconds of input are added to the billed length.

|---|---|---|
| 5s with audio | $0.50 | $0.75 |
| 5s silent | $0.25 | $0.375 |
