Timecode Formats

The position of any device is most often described using timecode. Timecode represents time using hours, minutes, seconds, and frames to provide a location for each device. Each frame represents a visual film or video frame.

The following timecode formats are supported:

• LTC

  Longitudinal timecode or LTC is an analog signal that can be recorded on tape. It should be used for positional information primarily. It can also be used for speed and phase information as a last resort if no other clock source is available.

• VITC

  Vertical interval timecode or VITC is contained within a composite video signal. It is recorded onto video tape and is physically tied to each video frame.

• MTC

  MIDI timecode or MTC is identical to LTC except that it is a digital signal transmitted via MIDI.
