# AndThenAny Engine

The `AndThenAny` engine is the same as the AndAny engine, except for the following differences:

- Records in the additional tracks must start after the record in the `Input0` track. In other words, the `AndThenAny` engine enforces an additional TimestampCondition (in addition to any conditions that you specify):

  `startX >= start0`

- This engine is available only for processing video. It is not supported with images and documents.
