Longitudinal Timecode. Traditionally, timecode has been recorded along a linear track on videotape. It was recorded and read by a static head on videotape recorders so it could be easily read when the tape is moving forwards or backwards, but nothing was read during a freeze frame – when VITC, timecode recorded with the picture material, was still working. Today, with tape use now falling, actual linear TC is not so often used. However timecode is still in wide used to identify and access video frames.
