# Wan2.7-R2V Referensi-ke-Video

>  - Model referensi-ke-video Alibaba Cloud Wanxiang 2.7
- Buat video baru dengan gaya, karakter, dan adegan yang konsisten berdasarkan satu atau beberapa gambar/video referensi
- Mendukung konsistensi karakter, transfer gaya, dan kombinasi multi-aset
- Mendukung suara referensi (reference_voice) untuk mengontrol suara karakter

  Opsi:

  * `720P` - Standar
  * `1080P` - Definisi tinggi (default)
</ParamField>

<ParamField body="duration" type="integer" default="5">
  Durasi video (detik)

  Rentang yang didukung: `2` \~ `15` detik

  Default: `5`

  <Warning>
    Ketika aset referensi mencakup video: bilangan bulat antara \[2, 10].

    Ketika aset referensi tidak mencakup video: bilangan bulat antara \[2, 15].
  </Warning>
</ParamField>

<ParamField body="size" type="string" default="16:9">

## Kasus Penggunaan

### Kasus 1: Satu Gambar Referensi (Paling Sederhana)

```json theme={null}
{
  "model": "wan2.7-r2v",
  "prompt": "This person walks down the street surrounded by heavy traffic",
  "image_with_roles": [
    { "url": "https://cdn.example.com/character.jpg", "role": "reference_image" }
  ]
}
```

### Kasus 2: Beberapa Gambar Referensi

```json theme={null}
{
  "model": "wan2.7-r2v",
  "prompt": "The character in image 1 enters the scene in image 2 and mimics the pose in image 3",
  "image_with_roles": [
    { "url": "https://cdn.example.com/person.jpg", "role": "reference_image" },
    { "url": "https://cdn.example.com/background.jpg", "role": "reference_image" },
    { "url": "https://cdn.example.com/pose.jpg", "role": "reference_image" }
  ],
  "resolution": "1080P",
  "duration": 8,
  "size": "16:9"
}
```

### Kasus 3: Pembuatan Berdasarkan Video Referensi

```json theme={null}
{
  "model": "wan2.7-r2v",
  "prompt": "Generate a beach sunset scene in the style of the reference video",
  "video_urls": ["https://cdn.example.com/style_reference.mp4"],
  "resolution": "720P",
  "duration": 8
}
```

### Kasus 4: Bingkai Pertama Ditentukan + Gambar Referensi

```json theme={null}
{
  "model": "wan2.7-r2v",
  "prompt": "The reference character starts from this position and walks forward",
  "image_with_roles": [
    { "url": "https://cdn.example.com/character.jpg", "role": "reference_image" },
    { "url": "https://cdn.example.com/start.jpg", "role": "first_frame" }
  ],
  "resolution": "1080P",
  "duration": 8
}
```

### Kasus 5: Gambar Referensi + Suara Referensi (Presisi)

```json theme={null}
{
  "model": "wan2.7-r2v",
  "prompt": "This person walks down the street while speaking",
  "image_with_roles": [
    {
      "url": "https://cdn.example.com/character.jpg",
      "role": "reference_image",
      "reference_voice": "https://cdn.example.com/voice_sample.mp3"
    }
  ],
  "resolution": "1080P",
  "duration": 10
}
```

## Aturan Referensi Gambar

Dengan beberapa gambar referensi, gunakan indeks numerik dalam `prompt` untuk merujuknya:

* Gambar ke-1 → "gambar 1" atau "gambar pertama"
* Video ke-1 → "video 1" atau "video pertama"

<Note>
  **Kueri Hasil Tugas**

  Pembuatan video adalah tugas asinkron yang mengembalikan `task_id` saat dikirim. Gunakan endpoint [Dapatkan Status Tugas](/id/api-reference/tasks/status) untuk mengueri progres dan hasil pembuatan.
