Using Source-LTC
This article is part of the Source-LTC User GuideThere are many ways to use Source-LTC. Below are some examples:
Example 1: Chasing SMTPE time code
In the case of ADR sessions, some theatrical work, and post production mix stages, you will need to chase SMPTE sent to you from a remote connection or some local system however you lack the hardware to read and chase the SMPTE timecode. Source-LTC can be used as a SMPTE Reader to convertSMPTE to MIDI TimeCode (MTC) which can be read by most any DAW.
Example 2: Generating SMTPE timecode
In the case of ADR sessions, some theatrical work, and post production mix stages where you need to send SMPTE to a remote connection or some local system but you lack the hardware to generate SMPTE timecode. Source-LTC can be used as a SMPTE generator to convert MIDI TimeCode (MTC) to SMPTE tImecode as required.
Advanced Example 3A: Converting RTS to SMPTE/MIDI via Source-LTC
You need to run you Source-Connect system on a separate computer that is perhaps outside of your local network for security reasons. Doing so would usually mean you cannot use the Remote Transport Sync (RTS) feature in Source-Connect; however using Source-LTC the RTS workflow can be preserved and the other side of the Source-Connect connection doesn’t need to change their workflow or lose a channel on the audio stream for timecode: RTS doesn’t use up an audio channel for Sync as SMPTE does. Here, the mix stage inside the LAN can send SMPTE to the computer running Source-Connect and Source-LTC. When Source-LTC locks to SMPTE it will in turn send MTC to a DAW installed on the same Source-Connect computer. The DAW will then chase the SMPTE and, in turn, if Connected on Source-Connect and if RTS is engaged as Send, the remote connection on Source-Connect will effectively chase the SMPTE timecode from the stage using RTS.
Advanced Example 3B:
The reverse of this is also possible so that if the mix stage needs to chase SMPTE from the remote connection but the remote location lacks a SMPTE generator and they don’t want to lose a connection channel to SMPTE then the Source-Connect computer can have its RTS set to Receive so the DAW running on the Source-Connect computer will chase the remote side. When the DAW on the Source-Connect computer goes in to play it can be set to generate MTC that is delivered to Source-LTC which in turn generates SMPTE timecode for the stage to chase.
