# Output

Usually a configuration contains at least one output task. The following example includes an output task named `IDOL`:

    [Session]
    Engine0=Ingest
    Engine1=FaceDetect
    Engine2=FaceRecognize
    Engine3=IDOL

    [IDOL]
    Type=IDOL
    Input=FaceRecognize.Result
    // idol engine options

All output tasks can include the configuration parameter `Input`. This specifies a comma-separated list of tracks that you want to output to an external system. If you do not specify a list of tracks, Media Server outputs a default selection of tracks. For information about whether a track is output by default, refer to the Media Server Reference.

Output engines do not produce records, and therefore do not have output tracks.
