SECTION 8.3
TIMECODE CONFIGURATION
TriCaster can supply event time values based on the system clock, when necessary.
To access timecode options, click the small gear icon next to the timecode display
at right in Live Desktop’s Dashboard.
Hint: You can set TriCaster’s system clock as for any computer by exiting to the
Windows® Desktop.
Advanced Edition TriCasters can optionally use an external linear timecode
(LTC) reference to drive their clocks (and timecode for capture).
We’ll discuss the shared timecode features first, and then focus on the
unique aspects of the LTC timecode support (Section 8.3.3).
8.3.1
SUBTRACT 12 HOURS
The current time value is embedded in the frames of Quicktime video files
captured during the session using TriCaster’s Record function. For this
reason, a switch labeled Subtract 12 Hours is provided.
This option permits you to avoid confusion that might arise when
sequencing files based on timecode that ‘wraps around’ past midnight.
(Otherwise, for example, a video frame recorded one minute before
midnight would be assigned the timecode 23:59:59.00, while frames recorded one minute or more later
would have timecode ≥ 01:00:00.00 – seemingly a lower (i.e., ordinarily earlier) timecode value.)
8.3.2
EVENT TIME
FIGURE 8-27 FIGURE 8-28
Two more switches, under the label Indicate Event Time, allow you to configure Start and End times for your
upcoming show. Beside each of these is an editable time field. Enable the Start/End switches, and click inside
the field to modify the time value by direct entry, or drag left right to raise or lower the current value.
During live production, the Dashboard and as well as TriCaster’s monitor panes and default Multiview layouts
(Figure 8-28) offer Broadcast Clock displays based on the current timecode.
Secondary clock displays show a useful countdown to the (production) Start and End times when the
corresponding switches are enabled in the Timecode Configuration panel.
