# Scaricare contenuti video Sora 2

> Recupera i dati binari del video Sora 2 generato tramite GET /v1/videos/{video_id}/content in CometAPI per scaricare gli output video completati tramite video_id.

Usa questo endpoint per scaricare l'output Sora finale dopo che il job ha raggiunto `completed`. Fino ad allora, restituisce un errore invece di un file video.

## Prima di scaricare

* Attendi finché [Retrieve Video](./retrieve) non riporta `status: completed`
* Passa il `video_id` dal passaggio di creazione
* Salva il file nel tuo bucket o CDN se hai bisogno che resti disponibile oltre la finestra temporanea di consegna del provider

## Flusso di download

<Steps>
  <Step title="Crea il video">
    Inizia con [Create Video](./create).
  </Step>

  <Step title="Verifica il completamento">
    Usa [Retrieve Video](./retrieve) finché il job non raggiunge `completed`.
  </Step>

  <Step title="Recupera il file binario">
    Chiama questo endpoint per scaricare l'MP4 o un'altra variante di asset supportata.
  </Step>
</Steps>

## Finestra temporanea di consegna

Una volta completato il rendering, recupera il file tempestivamente. L'URL di consegna del provider non è permanente.

        Call this endpoint only after GET /v1/videos/{video_id} reports a
        completed job. Before completion, CometAPI returns a JSON error response
        instead of a file. Shortly after completion the file can still be
        propagating; a transient `502` from this endpoint resolves on retry.
