## README

### Wan 2.2 Animate Replace

Swap the person in a reference `video` for the character in `image`. Motion, camera, and scene come from the video; the new character's look comes from the picture, relit to fit the scene.

#### Fields

| Field | Type | Default | Notes |
|---|---|---|---|
| `image` | image URL, required | — | Character image. JPEG, PNG, or WebP URL. |
| `video` | video URL, required | — | Reference video that supplies the motion. |
| `resolution` | `480p` / `580p` / `720p` | `720p` | Sets the rate. |
| `use_turbo` | boolean | false | Faster generation at some quality cost. |
| `seed` | integer 0–2147483647 | random | Fix it to compare prompt changes. |

#### Billing

Billing follows the upstream unit: output seconds counted at 16 frames per second, so a 30fps output bills about 1.9× its wall-clock length. Rates per counted second: $0.04 at 480p, $0.06 at 580p, $0.08 at 720p. The quote before submission assumes a 5-second, 30fps result; the final charge uses the measured output.

| Output | 480p | 580p | 720p |
|---|---|---|---|
| 5s at 30fps | $0.375 | $0.5625 | $0.75 |
| 10s at 30fps | $0.75 | $1.125 | $1.50 |
| 10s at 16fps | $0.40 | $0.60 | $0.80 |

Failed runs are not charged.

#### Prompting

- Match the character image's pose and framing to the person in the video where possible.
- Avoid videos with several people overlapping the subject.

#### Limits

- Output length follows the reference video.
