# Analysis

This section describes parameters that you can use to configure analysis tasks. Set these parameters in the configuration that you pass to the `process` action when you begin processing, and not in the Media Server configuration file.

In the `[Session]` section, use the `Engine` parameter to specify the names of your tasks. Each name refers to another section in the configuration that contains settings for the task.

You can specify a comma-separated list of names:

    [Session]
    Engine=IngestVideo,FaceDetection,FaceRecognition,ResizeImages,EncodeImagesToDisk,OutputToIDOL

Alternatively, you can use numbered parameters. Use a unique number for each task, starting from zero (0) and increasing by one each time:

    [Session]
    Engine0=IngestVideo
    Engine1=FaceDetection
    Engine2=FaceRecognition
    Engine3=ResizeImages
    Engine4=EncodeImagesToDisk
    Engine5=OutputToIDOL

NOTE: Task names cannot include any of the following characters:

- period (`.`)
- comma (`,`)
- colon (`:`)
- semicolon (`;`)
- asterisk (`*`)
- equals sign (`=`)
