# Input

The name of the track to analyze.

- When the input is images, Media Server classifies each image separately.
- When the input is video from an ingest engine, or an engine that does not support tracking, Media Server begins a new result when the classification changes significantly.
- When the input is video from an engine that supports tracking (for example number plate recognition), results begin and end at the times provided by the other analysis task (for example when the vehicle appears and disappears). The IDs used for the image classification records are also inherited from the input records.

The default value analyzes the first image track produced by the ingest engine.

To analyze a different track, specify the name in the format `taskName.trackName`, where `taskName` is the name of the task that produced the track.
