# Extract an asset as mp4

POST https://device.example.com:443/cluster1/vos-api/asset-acquisition/v1/asset/{id}/download
Content-Type: application/json

Reference: https://mediakind.ferndocs.com/harmonic/api/vos/asset-acquisition/extract-asset-as-mp-4

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `id` (string, required) — ID of asset

### Query parameters

- `force` (boolean, optional, default: false) — Allow to force the creation of a new extract even if one already exists from a previous extraction and has not expired

### Body (application/json)

This endpoint expects a com.harmonicinc.vos.asset.acquisition.rest.model.ExtractionParameters.

- `audioLanguages` (list of string, optional) — A list of audio languages to include in the extraction. To include all languages, set this null or remove it.
- `expirationDuration` (integer, optional) — Download link expiration duration in minutes Default value 1440. Minimum value 5 minutes and maximum value 1440 minutes (24 hours).
- `ismGeneration` (boolean, optional) — Flag to indicate if ISM file needs to be generated for the extracted asset. Default value is false.
- `profileIndex` (integer, optional) — An index (from 1 to xx) for the size of the rendition to convert. index '1' means the bigger rendition in size will be converted. To convert all renditions, set this to null or remove it. The trimming is not frame accurate, the extracted file will be larger than the requested parameters, based on I frames position.
- `trimParameters` (list of com.harmonicinc.vos.asset.acquisition.rest.model.conversion.TrimParameters, optional) — A list of trim parameters to include in the conversion the full or a portion of the asset. To not apply any trimming, set this to null or remove it.
- `whitelistIps` (list of string, optional) — White list of comma separated IP addresses. Example: 192.168.1.1, 10.10.10.0/24
