# Input

The name of the track that contains the metadata to use to draw the overlay (the input does not need to contain the video frames). For example, to draw an overlay that shows detected faces, you could use the `Result` track from a face detection task.

Specify the name of the track in the format `taskName.trackName`. For example, to specify the `Result` track produced by the `MyFaceRecognition` task, set this parameter to `MyFaceRecognition.Result`.
