# Pembuatan Video Kling v3

>  - Mode pemrosesan asinkron, mengembalikan ID tugas untuk kueri berikutnya
- Mendukung teks-ke-video, gambar-ke-video (kontrol frame pertama/frame pertama-terakhir)
- Mendukung mode standar (720P), mode profesional (1080P), dan mode 4K
- Mendukung durasi video 3 hingga 15 detik
- Mendukung pembuatan video dengan audio

## 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 request:

```
Authorization: Bearer YOUR_API_KEY
```

## Parameter Request

**model** `string` *required*

Nama model pembuatan video

Model yang didukung:

* `kling-v3` - Kling v3 (direkomendasikan)

**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

Jelaskan adegan, aksi, dan gaya secara detail untuk hasil pembuatan yang lebih baik. Prompt bahasa 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, distorted"`

**mode** `string` (default: std)

Mode pembuatan

Opsi:

* `std` - Mode standar (720P)
* `pro` - Mode profesional (1080P)
* `4k` - Mode 4K

Default: `std`

**duration** `integer` (default: 5)

Default: `5`
Durasi video (detik)

Rentang: 3-15 (minimum 3 detik, maksimum 15 detik)

**⚠️ Catatan:** Harus berupa angka biasa (misalnya `6`), jangan tambahkan tanda kutip, jika tidak akan terjadi error

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

Rasio aspek video

Opsi:

* `16:9` - Lanskap
* `9:16` - Potret
* `1:1` - Persegi

Default: `16:9`

**image\_urls** `array\<url\>`

Saat menggunakan `element_list`, Anda wajib memberikan setidaknya 1 gambar melalui `image_urls`.

Array URL gambar untuk pembuatan gambar-ke-video

* Berikan **1 gambar**: digunakan sebagai bingkai pertama
* Berikan **2 gambar**: secara otomatis ditetapkan sebagai bingkai pertama + bingkai terakhir

Maksimum 2 gambar didukung

Contoh: `["https://example.com/first.jpg"]`

> [!WARNING]
>
> * Maksimum 2 gambar yang didukung
> * URL gambar harus dapat diakses publik tanpa proteksi hotlink
> * Dalam mode gambar-ke-video, `aspect_ratio` dapat ditimpa oleh rasio gambar aktual

**watermark** `boolean`

Apakah menambahkan watermark

**audio** `boolean` (default: false)

Apakah membuat video dengan audio

**multi\_shot** `boolean` (default: false)

Apakah mengaktifkan mode multi-shot.

* `true`
* `false`

**shot\_type** `string`

Metode pemisahan shot: `customize` / `intelligence`.

Wajib saat `multi_shot=true`.

**multi\_prompt** `array\<object\>`

Informasi per shot, seperti prompt dan durasi.

Tentukan urutan shot, prompt, dan durasi melalui `index`, `prompt`, dan `duration`.

* Mendukung 1 hingga 6 shot
* Panjang konten maksimum per shot adalah 512
* Setiap durasi shot harus >= 1 dan tidak boleh melebihi total durasi tugas
* Jumlah semua durasi shot harus sama dengan `duration` tingkat atas

Format:

```json theme={null}
"multi_prompt": [
  { "index": 1, "prompt": "string", "duration": 5 },
  { "index": 2, "prompt": "string", "duration": 5 }
]
```

Wajib saat `multi_shot=true` dan `shot_type=customize`.

**element\_list** `array\<object\>`

Saat menggunakan `element_list`, Anda wajib memberikan setidaknya 1 gambar melalui `image_urls`.

> [!WARNING]
>
> Jika tidak ada gambar yang diberikan melalui `image_urls`, informasi elemen dalam `element_list` mungkin tidak diterapkan. `element_input_urls` menentukan gambar referensi subjek dan tidak dapat menggantikan `image_urls`.

Daftar subjek referensi, hingga 3 subjek.

* Buat secara langsung melalui `name`, `description`, `element_input_urls`

Contoh:

```json theme={null}
[
  {
    "name": "element_dog",
    "description": "a golden retriever, fluffy fur, friendly expression",
    "element_input_urls": [
      "https://example.com/image1.png",
      "https://example.com/image2.png"
    ]
  },
  {
    "name": "element_cat",
    "description": "an orange tabby cat, round face, bright eyes",
    "element_input_urls": [
      "https://example.com/image1.png",
      "https://example.com/image2.png"
    ]
  }
]
```

Catatan:

* `name`, `description`, dan `element_input_urls` wajib untuk pembuatan secara langsung
* `element_input_urls`: 2-4 gambar per subjek (yang pertama sebagai gambar frontal, sisanya sebagai referensi)
* Rujuk elemen dalam `prompt` dengan `@name`, misalnya `"@element_dog chasing @element_cat on grass"`

### Kendala Parameter

* `mode=4k` didukung untuk `kling-v3`
* `image_urls` mendukung hingga 2 gambar (1 bingkai pertama, 2 bingkai pertama+terakhir)
* Saat menggunakan `element_list`, Anda wajib memberikan setidaknya 1 gambar melalui `image_urls`.
* Input hanya bingkai terakhir tidak valid (harus menyertakan bingkai pertama)
* Saat `multi_shot=true`, `prompt` tingkat atas dapat dihilangkan
* `multi_prompt` mendukung hingga 6 shot, dan `index` harus dimulai dari 1 dan berurutan

## Matriks Dukungan Fitur
