# Génération vidéo VEO3

>  - Mode de traitement asynchrone, renvoie un identifiant de tâche pour les requêtes ultérieures
- Prend en charge plusieurs modes de génération, dont texte-vers-vidéo et image-vers-vidéo
- Prend en charge la sortie en résolution **4K**
- Les liens des vidéos générées sont valides pendant 24 heures, veuillez les enregistrer rapidement 

> [!NOTE]
>
> **Alias de modèle compatible** : cette API prend également en charge les alias `veo3.1-fast-ext` (équivalent à `veo3.1-fast`), `veo3.1-quality-ext` (équivalent à `veo3.1-quality`) et `veo3.1-lite-ext` (équivalent à `veo3.1-lite`) ; ils sont interchangeables avec leurs noms respectifs et produisent des résultats identiques.

## Autorisation

**Authorization** `string` *required*

Tous les points de terminaison de l'API nécessitent une authentification par Bearer Token

Obtenez votre API Key :

Rendez-vous sur la [page de gestion des API Keys](https://gccai.heqingsong.uk/keys) pour obtenir votre API Key

Ajoutez-la dans l'en-tête de la requête :

```
Authorization: Bearer YOUR_API_KEY
```

## Paramètres de la requête

**model** `string` *required* (default: veo3.1-fast)

Nom du modèle de génération vidéo

Modèles disponibles :

* `veo3.1-fast` — modèle de génération rapide, adapté aux prévisualisations et itérations rapides (alias compatible `veo3.1-fast-ext`)
* `veo3.1-quality` — modèle de génération haute qualité, adapté à la production finale (alias compatible `veo3.1-quality-ext`)
* `veo3.1-lite` — modèle de génération léger, adapté à la génération par lots à faible coût (alias compatible `veo3.1-lite-ext`)

Exemple : `"veo3.1-fast"`

> [!NOTE]
>
> Pour assurer la compatibilité avec les anciens appels, les alias `veo3.1-fast-ext` (correspondant à `veo3.1-fast`), `veo3.1-quality-ext` (correspondant à `veo3.1-quality`) et `veo3.1-lite-ext` (correspondant à `veo3.1-lite`) restent utilisables normalement.

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

Indique s'il faut modérer le contenu avant d'envoyer la tâche vidéo.

* `true` : vérifier les prompts et les images d'entrée avec `omni-moderation-latest`
* `false` ou omis : ne pas envoyer de requête de modération, sans coût ni latence de modération supplémentaires (par défaut)

**prompt** `string` *required*

Description textuelle pour la génération vidéo

**duration** `integer`

Durée de la vidéo en secondes

Valeur fixe : `8` (VEO3 ne prend en charge qu'une durée de 8 secondes)

**aspect\_ratio** `string`

Rapport d'aspect de la vidéo

Formats pris en charge :

* `16:9` (paysage)
* `9:16` (portrait)

**generation\_type** `string`

Type de génération vidéo

Types pris en charge :

* `frame` — image-vers-vidéo (mode FL)
* `reference` — vidéo à partir d'une image de référence

Si non spécifié, défini par défaut en fonction du nombre d'images : 2 images pour image-vers-vidéo, 3 images pour vidéo à partir d'une image de référence

**Remarque : le modèle `veo3.1-quality` ne prend pas en charge le mode `reference`**

> [!WARNING]
>
> Le modèle `veo3.1-lite` ne prend pas en charge ce paramètre, ne le transmettez pas

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

Tableau d'URL d'images de référence pour la génération image-vers-vidéo

Prend en charge les URL d'images accessibles publiquement (http\:// ou https\://)

Exemple : `["https://example.com/image.jpg"]`

**Limitations :**

* Maximum 3 images
* Pour le mode image-vers-vidéo : la première image est l'image de début, la seconde est l'image de fin
* Taille maximale du fichier : 10 Mo
* Formats pris en charge : .jpeg, .jpg, .png, .webp

> [!WARNING]
>
> Le modèle `veo3.1-lite` ne prend pas en charge ce paramètre, ne le transmettez pas

**resolution** `string`
