# Pembuatan Video Resmi VEO3

>  - Mode pemrosesan asinkron, mengembalikan ID tugas untuk kueri berikutnya
- Mendukung teks-ke-video dan gambar-ke-video (kontrol frame pertama / frame pertama & frame terakhir)
- Mendukung resolusi 720P dan 1080P
- Mendukung durasi video 4/6/8 detik
- Mendukung pembuatan trek audio
- Mendukung kontrol kebijakan pembuatan orang

## Otorisasi

**Authorization** `string` *required*

Semua endpoint API memerlukan autentikasi Bearer Token

Dapatkan API Key Anda:

Kunjungi [Halaman Manajemen API Key](https://gccai.heqingsong.uk/keys) untuk mendapatkan API Key Anda

Tambahkan ke header permintaan:

```
Authorization: Bearer YOUR_API_KEY
```

## Parameter Permintaan

**model** `string` *required*

Nama model pembuatan video

Model yang tersedia:

* `veo3.1-fast-official` - Veo 3.1 Resmi Versi Cepat
* `veo3.1-quality-official` - Veo 3.1 Resmi Versi Kualitas Tinggi

**nsfw\_check** `boolean` (default: false)

Menentukan apakah moderasi konten dijalankan sebelum tugas video dikirim.

* `true`: periksa prompt dan gambar input dengan `omni-moderation-latest`
* `false` atau dihilangkan: tidak mengirim permintaan moderasi, tanpa biaya atau latensi moderasi tambahan (default)

**prompt** `string` *required*

Prompt teks positif

Jelaskan adegan, aksi, gaya, dan lainnya secara detail untuk hasil pembuatan yang lebih baik. Prompt berbahasa Inggris direkomendasikan.

Contoh: `"a golden retriever running on the beach, sunset, cinematic"`

**negative\_prompt** `string`

Prompt negatif untuk mengecualikan konten yang tidak diinginkan

Contoh: `"blurry, low quality, watermark, text"`

**duration** `integer` (default: 8)

Durasi video dalam detik

Nilai yang direkomendasikan: `4` / `6` / `8`

Default: `8`

**Catatan:** Harus berupa angka murni (misalnya `8`), jangan tambahkan tanda kutip, jika tidak error akan terjadi

**aspect\_ratio** `string` (default: 16:9)

Rasio aspek video

Nilai yang tersedia:

* `16:9` - Lanskap
* `9:16` - Potret

Default: `16:9`

**resolution** `string` (default: 720p)

Resolusi video

Nilai yang tersedia:

* `720p` - Resolusi standar
* `1080p` - Definisi tinggi
* `4K` - Definisi ultra tinggi

Default: `720p`

**first\_frame\_image** `string`

URL gambar frame pertama untuk pembuatan gambar-ke-video

> [!WARNING]
>
> * URL gambar harus dapat diakses publik tanpa proteksi hotlink
> * URL object storage lebih direkomendasikan daripada tautan unduhan sementara

**last\_frame\_image** `string`

URL gambar frame terakhir untuk pembuatan gambar-ke-video

Digunakan bersama `first_frame_image` untuk mengontrol frame pertama dan terakhir

**seed** `integer`

Seed acak untuk mereproduksi hasil pembuatan

Rentang nilai: `0` - `4294967295`

**sample\_count** `integer` (default: 1)

Jumlah sampel yang akan dihasilkan (1-4), saat ini direkomendasikan untuk menggunakan `1`

Default: `1`

**generate\_audio** `boolean` (default: false)

Apakah membuat trek audio

**person\_generation** `string` (default: allow\_adult)

Kebijakan pembuatan orang

Nilai yang tersedia:

* `allow_adult` - Hanya mengizinkan pembuatan orang/wajah dewasa
* `disallow` - Tidak mengizinkan pembuatan orang atau wajah

Default: `allow_adult`

**resize\_mode** `string` (default: pad)

Strategi pengubahan ukuran gambar (berlaku untuk gambar-ke-video)

Nilai yang tersedia:

* `pad` - Mode padding
* `crop` - Mode cropping

Default: `pad`

**enhance\_prompt** `boolean` (default: true)

Apakah mengaktifkan peningkatan prompt upstream

Default: `true`

> [!WARNING]
>
> * Parameter ini hanya dapat diatur ke `true`. Mengaturnya ke `false` akan menyebabkan error permintaan
> * Jika Anda tidak memerlukan parameter ini, jangan sertakan

## Teks-ke-Video vs Gambar-ke-Video

Sistem otomatis menentukan mode berdasarkan apakah parameter gambar disediakan: tanpa gambar untuk teks-ke-video, dengan gambar untuk gambar-ke-video.

| Parameter | Teks-ke-Video | Gambar-ke-Video |
| - | - | - |
| `prompt` | Wajib | Wajib |
| `first_frame_image` | Tidak digunakan | Wajib (setidaknya satu) |
| `last_frame_image` | Tidak digunakan | Opsional (frame terakhir) |
| `negative_prompt` | Opsional | Opsional |
| `duration` | Opsional | Opsional |
| `aspect_ratio` | Opsional | Opsional |
| `resolution` | Opsional | Opsional |
| `seed` | Opsional | Opsional |
| `generate_audio` | Opsional | Opsional |
| `person_generation` | Opsional | Opsional |
| `resize_mode` | Tidak berlaku | Opsional |
| `enhance_prompt` | Opsional | Opsional |

## Respons

**code** `integer`

Kode status respons, 200 jika berhasil

**data** `array`

Array data respons

**Properti**

**status** `string`

Status tugas, awalnya `submitted` saat pengiriman

**task\_id** `string`

Pengidentifikasi tugas unik untuk mengueri status dan hasil tugas

## Skenario Penggunaan

### Skenario 1: Teks-ke-Video (Dasar)

```json theme={null}
{
  "model": "veo3.1-fast-official",
  "prompt": "a golden retriever running on the beach, sunset, cinematic"
}
```

### Skenario 2: Teks-ke-Video (Parameter Lengkap)

```json theme={null}
{
  "model": "veo3.1-quality-official",
  "prompt": "a cinematic close-up of a ragdoll cat slowly walking through a sunlit living room",
  "negative_prompt": "blurry, low quality, watermark, text",
  "duration": 8,
  "aspect_ratio": "16:9",
  "resolution": "1080p",
  "seed": 12345,
  "generate_audio": true,
  "person_generation": "disallow",
  "enhance_prompt": true
}
```

### Skenario 3: Gambar-ke-Video (Frame Pertama Tunggal)

```json theme={null}
{
  "model": "veo3.1-fast-official",
  "prompt": "the cat slowly walks forward and looks around",
  "first_frame_image": "https://example.com/cat.png",
  "duration": 8,
  "resolution": "720p"
}
```

### Skenario 4: Gambar-ke-Video (Frame Pertama + Frame Terakhir)

```json theme={null}
{
  "model": "veo3.1-quality-official",
  "prompt": "smooth cinematic transition from the first frame to the last frame",
  "first_frame_image": "https://example.com/frame-start.png",
  "last_frame_image": "https://example.com/frame-end.png",
  "duration": 8,
  "resolution": "1080p"
}
```

### Skenario 5: Video dengan Audio

```json theme={null}
{
  "model": "veo3.1-quality-official",
  "prompt": "a busy coffee shop with people chatting and barista making latte art",
  "duration": 8,
  "generate_audio": true,
  "aspect_ratio": "16:9"
}
```

> [!NOTE]
>
> **Kueri Hasil Tugas**
>
> Pembuatan video adalah tugas asinkron yang mengembalikan `task_id` saat dikirim. Gunakan endpoint [Dapatkan Status Tugas](https://gccai.heqingsong.uk/id/api-reference/tasks/status.md) untuk mengueri progres dan hasil pembuatan.
