# Vidu Q3 (mix/standard) Reference-to-Video

>  - Modo de procesamiento asíncrono, devuelve un ID de tarea para consultas posteriores
- Suba 1-7 imágenes de referencia + prompt de texto para generar videos cortos que contengan los sujetos de referencia
- Admite resolución 540p / 720p / 1080p
- Rango de duración 1-16 segundos, ideal para mantener la coherencia de los personajes y la continuidad del estilo

## Autorización

**Authorization** `string` *required*

Todos los endpoints de la API requieren autenticación mediante Bearer Token

Obtenga su API Key:

Visite la [página de gestión de API Keys](https://gccai.heqingsong.uk/keys) para obtener su API Key

Añádala al encabezado de la solicitud:

```
Authorization: Bearer YOUR_API_KEY
```

## Parámetros de la solicitud

**model** `string` *required*

Nombre del modelo de generación de video

Modelos compatibles:

* `viduq3-mix` - Calidad premium, transiciones inteligentes más potentes, admite videos cortos de 1 segundo
* `viduq3` - Opción predeterminada, cambio de cámara más inteligente

> [!NOTE]
>
> **Cómo elegir**: Use `viduq3` para uso diario; use `viduq3-mix` para calidad premium o efectos de movimiento de 1-2 segundos.

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

Indica si se debe moderar el contenido antes de enviar la tarea de vídeo.

* `true`: revisar los prompts y las imágenes de entrada con `omni-moderation-latest`
* `false` u omitido: no enviar una solicitud de moderación, sin coste ni latencia de moderación adicionales (predeterminado)

**prompt** `string` *required*

Prompt de texto, máximo **5000 caracteres**

Describa acciones y movimientos de cámara, no la apariencia (la apariencia está determinada por las imágenes de referencia).

Ejemplo: `"Santa Claus and the bear hug by the lakeside"`

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

Array de URLs de imágenes de referencia, **1-7 imágenes**

Admite URLs de imágenes de acceso público (http\:// o https\://)

Ejemplo: `["https://example.com/santa.png", "https://example.com/bear.png"]`

> [!WARNING]
>
> * Cantidad: **1-7 imágenes**
> * Formatos compatibles: PNG, JPEG, JPG, WebP
> * Tamaño mínimo: 128×128
> * Relación de aspecto: entre 1:4 y 4:1
> * Tamaño máximo de archivo: ≤ 50MB por imagen
> * Deben ser URLs de acceso público

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

Duración del video (segundos)

* `viduq3-mix`: `1` a `16`
* `viduq3`: `3` a `16`

Predeterminado: `5`

> [!WARNING]
>
> `viduq3` admite un mínimo de 3 segundos, `viduq3-mix` admite un mínimo de 1 segundo. Pase una duración válida según el modelo seleccionado.

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

Resolución del video

* `viduq3-mix`: `720p` (predeterminado) / `1080p`
* `viduq3`: `540p` / `720p` (predeterminado) / `1080p`

> [!WARNING]
>
> `viduq3-mix` no admite `540p`, use `720p` o `1080p`.

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

Relación de aspecto del video

Opciones:

* `16:9` - Horizontal (predeterminado)
* `9:16` - Vertical
* `4:3` - Tradicional
* `3:4` - Vertical tradicional
* `1:1` - Cuadrado

**seed** `integer`

Semilla aleatoria para controlar la aleatoriedad de la generación

Si no se proporciona, se usará una semilla aleatoria.

> [!NOTE]
>
> Usar la misma semilla con parámetros idénticos producirá resultados similares, pero no se garantiza que sean exactamente iguales.

## Comparación de modelos

| Característica | `viduq3` | `viduq3-mix` |
| - | - | - |
| Recomendado para | Uso diario, cambio de cámara multiángulo | Calidad premium, efectos de movimiento de 1-2 segundos |
| Rango de duración | 3-16 segundos | 1-16 segundos |
| Resolución | 540p / 720p / 1080p | 720p / 1080p |
| Imágenes de referencia | 1-7 imágenes | 1-7 imágenes |

## Respuesta

**code** `integer`

Código de estado de la respuesta, 200 en caso de éxito

**data** `array`

Array de datos de la respuesta

**Elementos del array**

**status** `string`

Estado de la tarea, `submitted` en la solicitud inicial

**task\_id** `string`

Identificador único de la tarea para consultar el estado y los resultados

## Casos de uso

### Caso 1: Reference-to-Video básico con viduq3

```json theme={null}
{
  "model": "viduq3",
  "prompt": "Santa Claus and the bear hug by the lakeside",
  "image_urls": [
    "https://example.com/santa.png",
    "https://example.com/bear.png"
  ]
}
```

### Caso 2: Reference-to-Video de alta calidad con viduq3-mix

```json theme={null}
{
  "model": "viduq3-mix",
  "prompt": "A cyberpunk neon street with the cat from reference image walking by",
  "image_urls": [
    "https://example.com/cat-1.png",
    "https://example.com/cat-2.png",
    "https://example.com/cat-3.png"
  ],
  "duration": 8,
  "resolution": "1080p",
  "aspect_ratio": "16:9",
  "seed": 42
}
```

> [!NOTE]
>
> **Consultar los resultados de la tarea**
>
> La generación de video es una tarea asíncrona que devuelve un `task_id` al enviarse. Use el endpoint [Obtener estado de la tarea](https://gccai.heqingsong.uk/es/api-reference/tasks/status.md) para consultar el progreso y los resultados de la generación.
