# Descargar contenido de video Omni

> Descarga el archivo MP4 completado de una tarea beta de video Omni a través de la ruta de contenido.

Usa este endpoint para descargar el archivo MP4 de una tarea beta de video Omni completada. Si la tarea aún se está ejecutando, la API devuelve un error JSON en lugar de bytes de video.

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

## Antes de descargar

* Crea una tarea con [Crear un video Omni](./create).
* Consulta con [Recuperar un video Omni](./retrieve) hasta que `status` sea `completed`.
* Pasa el mismo ID de tarea a este endpoint.

## Almacenar medios completados

El cuerpo de la respuesta es contenido binario `video/mp4`. Guarda los bytes en tu propio almacenamiento cuando tu aplicación necesite acceso duradero a los medios generados.
