Linear editing: A method of editing program material where the final product is built cut by cut in a sequential or linear fashion. Changes to any edit require re-recording all of the succeeding edits or using the recorded master as a source. These systems are found at the very low end and very high end of the editing equipment market. They are comprised of a control computer, video tape recorders and switchers, and generally do not provide random access disk-based storage of source material, although connection to a digital disk recorder will provide limited random access capability.
LTC: Linear TimeCode (formerly known as Longitudinal TimeCode). Timecode is stored on a separate audio track and is one video frame time in duration.
