The IndexesVideosWrapperclass provides methods to manage the videos you’ve uploaded to the platform.

Methods

Retrieve video information

Description: This method retrieves information about the specified video.

Function signature and example:

1 retrieve(
2   indexId: string,
3   videoId: string,
4   request?: TwelvelabsApi.indexes.VideosRetrieveRequest,
5   requestOptions?: Videos.RequestOptions,
6 ): HttpResponsePromise<TwelvelabsApi.indexes.VideosRetrieveResponse>

Parameters:

Name	Type	Required	Description
`indexId`	`string`	Yes	The unique identifier of the index to which the video has been uploaded.
`videoId`	`string`	Yes	The unique identifier of the video to retrieve.
`request`	`TwelvelabsApi.indexes.VideosRetrieveRequest`	No	Request object containing optional parameters.
`requestOptions`	`Videos.RequestOptions`	No	Request-specific configuration.

The VideosRetrieveRequest interface has the following properties:

Name	Type	Required	Description
`embeddingOption`	`TwelvelabsApi.` `indexes.` `VideosRetrieveRequestEmbeddingOptionItem` or `TwelvelabsApi.` `indexes.` `VideosRetrieveRequestEmbeddingOptionItem[]`	No	Specifies which types of embeddings to retrieve. You can include one or more of the following values: - `visual-text`: Returns visual embeddings optimized for text search. - `audio`: Returns audio embeddings. To retrieve embeddings for a video, it must be indexed using the Marengo video understanding model version 2.7 or later. For details on enabling this model for an index, see the Create an index page. The platform does not return embeddings if you don’t provide this parameter. The values you specify in `embedding_option` must be included in the `model_options` defined when the index was created. For example, if `model_options` is set to `visual,` you cannot set `embedding_option` to `audio` or both `visual-text` and `audio`.
`transcription`	`boolean`	No	The parameter indicates whether to retrieve a transcription of the spoken words for the indexed video. Note that the official SDKs will support this feature in a future release.

Return value: Returns a HttpResponsePromise that resolves to a VideosRetrieveResponse object representing the retrieved video.
