# TrainVideoMatchClip

Trains Media Server to recognize a video clip.

Type: asynchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the database to add the video clip to. The database must already exist. | Yes
`identifier` | A unique identifier for the clip (maximum 254 bytes). If you do not set this parameter, Media Server generates an identifier automatically. | No
`metadata` | A comma-separated list of metadata key-value pairs to add to the clip. Separate keys from values using a colon (`:`). To include a comma or colon in a key name or value, you must enclose the key name or value in quotation marks (`"`) and escape any quotation marks that occur within the string with a backslash (`\`). | No
`nullvideodata` | A Boolean value (default false) that specifies whether to discard the video data when training is complete, rather than storing it in the database. | No
`trainingoptions` | A comma-separated list of training options to apply to the clip. Separate training options from their values using a colon (`:`). You can set the training option `maximumduration` to limit the amount of video used for training. For example, if you set `maximumduration:30s` then Media Server uses only the first 30 seconds of the video. This is usually sufficient for Media Server to identify a match. You cannot specify a value smaller than `10s`. | No
`videodata` | The video data. Files must be uploaded as multipart/form-data. For more information about sending data to Media Server, refer to the Media Server Administration Guide. | Set this or `videopath`
`videopath` | The path of the file that contains the video clip. The path must be absolute, or relative to the Media Server executable file. | Set this or `videodata`

## Example

The following example trains Media Server by sending the path of the video clip:

    curl http://localhost:14000 -F action=TrainVideoMatchClip
                                -F database=movies
                                -F videopath=clip.mp4
                                -F trainingoptions=maximumduration:45s

Alternatively, you can train Media Server by sending the video data, for example:

    curl http://localhost:14000 -F action=TrainVideoMatchClip
                                -F database=movies
                                -F videodata=@clip.mp4
                                -F trainingoptions=maximumduration:45s

## Response

This action is asynchronous, so Media Server always returns success accompanied by a token. You can use this token with the QueueInfo action to retrieve the status of your request.
