Using LTC Timecode for Output
You can use LTC (longitudinal or linear timecode) for output from your Avid editing application
through some Avid input/output hardware devices. The LTC OUT connector on the hardware
provides SMPTE or EBU timecode you can use as a sync source for decks with built-in
synchronizers or to stripe a destination tape. You can also use LTC to record non-drop-frame
timecode for downstream encoding.
For more information, see “Selecting the Timecode Format for Output” on page 1078 and
“Outputting Drop-Frame and Non-Drop-Frame Timecode Simultaneously for Downstream
Encoding” on page 1079.
To set LTC timecode for output:
1. In the Settings list in the Project window, double-click General.
2. Select “Generate LTC On Playback.”
3. Click OK.
Adding LTC Out During Preroll
You can add black filler to the beginning of a sequence when performing a digital cut. This
generates a preamble of LTC timecode before the actual digital cut begins. This preroll filler is
set to 1 second. The filler added to the beginning of the sequence is not written to tape. This
provides external hardware — such as a video overlay system — enough time to synchronize
with the sequence time before the start of playback.
You can select the LTC Out during preroll option in the Digital Cut tool to add filler at the start of
a sequence.
