Timecode Trigger Mode:
If you have access to incoming SMPTE LTC timecode, Session can be set to trigger recording im-
mediately (with Preroll) upon timecode lock, and stop recording (plus Postroll) on timecode unlock.
It is important to note that the 3d hardware can only read and record a SMPTE timecode
stream. Its presence (or lack thereof) is used only to trigger and/or de-trigger a Take
recording.
Mixer: Routing SMPTE Timecode Input to the Session
Like any other audio signal, timecode must first be routed to the Host computer through the Mixer
for the Session tracks to see it. Here is an example of Mixer Input Strip for SMPTE timecode:
Figure 12.37: 3d Mixer: a SMPTE-specific Input Strip
Since this input strip is specifically for routing timecode to the Session, the only really crucial Input
Strip settings are “Source”, and “To Host”. You may find the other strip elements shown to be useful
as well.
Important Note:
Best practice dictates that SMPTE should never be routed to a bus, where it might
potentially contaminate an audio feed.
On an Input strip carrying SMPTE (or FSK or any other data stream using audio as a carrier), all the
selectors below the ‘Record Enable’ button (eg. Link Groups, Mute Groups, DCA and Bus Assign)
should remain dark and un-assigned.
Input
Source (required):
Set the Input strip “Source” to your incoming SMPTE port. ULN-8 and LIO-8
3d boxes have dedicated 1/4" TRS SMPTE timecode I/O ports on the back panel (shown routed
above).
