An AndThen engine compares two tracks to identify events in the second track that occur within a specific time interval after (or at the same time as) events in the first track. The engine produces a track containing the identified record pairs. This section describes the parameters that you can set in the configuration section for an AndThen ESP task.
This engine is available only for processing video. It is not supported with images and documents.
