# Télécharger le contenu vidéo Omni

> Téléchargez le fichier MP4 terminé pour une tâche vidéo Omni bêta via la route de contenu.

Utilisez ce endpoint pour télécharger le fichier MP4 d’une tâche vidéo Omni bêta terminée. Si la tâche est encore en cours d’exécution, l’API renvoie une erreur JSON au lieu d’octets vidéo.

<Badge color="orange" size="sm" shape="pill">Bêta</Badge>

## Avant de télécharger

* Créez une tâche avec [Créer une vidéo Omni](./create).
* Interrogez avec [Récupérer une vidéo Omni](./retrieve) jusqu’à ce que `status` soit `completed`.
* Transmettez le même ID de tâche à ce endpoint.

## Stocker le média terminé

Le corps de la réponse contient un contenu binaire `video/mp4`. Enregistrez les octets dans votre propre stockage lorsque votre application a besoin d’un accès durable au média généré.
