any unknowingly created mental picture that appears to have been a record of the physical universe but is, in fact, only an altered copy of the time track. (It is a phrase taken from the motion pictureindustry, meaning to record dialogue and various sounds and then integrate them into the film after it has been shot. This is done for scenes where the original recording is faulty, for scenes where it is simply more convenient to add dialogue and other sound later, and for films playing abroad which require new dialogue in the native language of the host country.) —AcademyLevel 0 Glossary Approved 3-12-90
