Linear timecode has long served as a method of sharing an external timecode reference in video production.  Output from an external timecode generator is supplied to devices in the video pipeline using a standard audio connection. TriCaster 460, 860 and 8000 support ‘LTC’.

4RU TriCaster Advanced Edition models use Audio Input 7 for timecode input.  Sound from audio input 7 on these models is automatically muted for recording and output purposes, but you can un-mute it briefly in the Audio Mixer to let you adjust input levels.

For TriCaster 460, connect LTC to the 1/8” motherboard Line input connector (see also Section 3.6).  TriCaster decodes time stamps from the audible signal, and uses the values for clock displays and embedded timecode when recording video.  This is a great asset for post-production purposes.

Hint: The timecode display in the Live Desktop titlebar is tinted blue when external timecode is in use. If the external connection is lost for any reason, the display changes to white. TriCaster will attempt to maintain continuous timecode from the interruption on, until a valid signal is restored (in which case the display turns blue once more).
