# ListVideoMatchClips

Returns a list of video clips in a specified database.

Type: synchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the database to query. | Yes
`identifier` | A comma-separated list of identifiers to specify the clips to list. If you do not set this parameter, Media Server lists all of the clips in the specified database. | No
`maxresults` | The maximum number of clips to return. | No
`metadata` | A Boolean value (default false) that specifies whether to return the metadata associated with each clip. | No
`start` | The starting point for the list when you set the `maxresults` parameter. For example, to start listing clips from the tenth clip in the database, set `start=10`. The entries in the database are indexed from 1. | No
`trainingoptions` | A Boolean value (default false) that specifies whether to return the training options set for each clip. | No
`videostatus` | A Boolean value (default false) that specifies whether to report the status of training and whether the video data is stored in the database. | No

## Example

The following example lists up to 10 clips contained in the `movies` database:

    /action=ListVideoMatchClips&database=movies
                               &start=1
                               &maxresults=10
                               &metadata=true

## Response

The following XML shows an example response that includes a single video match clip.

              <hasvideodata>true</hasvideodata>
            </video>
          </videos>
          <trainingoptions>
            <trainingoption>
              <key>maximumduration</key>
              <value>30s</value>
            </trainingoption>
          </trainingoptions>
          <metadata>
            <item>
              <key>released</key>
              <value>2021</value>
            </item>
          </metadata>
        </entry>
      </responsedata>
    </autnresponse>

The `identifier` element shows the identifier that was assigned to the clip.

The `numtrained` element should contain the value `1`. If it contains the value `0` and the `numfailed` element contains the value `1`, then training was unsuccessful.

The `videos` element is present only when you set the action parameter `videostatus=true`. This element always contains one video, and includes the following information:

- `label` always matches the `identifier` for the clip.
- `status` shows the status of training.
- `hasvideodata` specifies whether the video clip that was used to train Media Server is stored in the database. If this element contains the value `false`, the video has been discarded and only the training is stored in the database. See NullVideoMatchVideoData.

The `trainingoptions` element shows the options that have been set to customize training. You can set training options with the `trainingoptions` parameter when you run the action TrainVideoMatchClip.

The `metadata` element contains custom metadata that you have added to the clip using AddVideoMatchClipMetadata. To see the metadata you must set the action parameter `metadata` to `TRUE`.
