7.3.1 PRODUCTION TIME DISPLAY
The control group labeled Production Time Display allows you to
enter time values that are specific to the current event. When the
Start switch is lit, the time you set in the numeric field at right is
used to supply the Production Start time display in Multiview
screen layouts that include clocks).
This provides a convenient warning as the time for your event
nears. In similar fashion, enabling the End switch and entering an
appropriate time displays a countdown to the end of the event
(shown once the Start time is surpassed) when clocks are displayed
on Multiview.
Tip: You can modify time values by clicking them and typing, or by
dragging the mouse point over them. You can ignore timecode
punctuation when entering numbers by typing the digits using 24
hour notation (for example, to enter 5:00.00 AM, press “5”, then
Enter. To set the time to 3:30 PM, type “1530” and press Enter.)
7.3.2 TIME
The Timecode control group menu allows you to select between
timecode sources as follows:
Tip: If the LTC source fails, the system automatically reverts to
Internal (System Clock) after a moment or two (an error flash
message is displayed in the Status Bar – see Section 6.4.1).
Another switch in the Time group allows you to optionally Subtract 12
Hours from the actual timecode. This lets you avoid confusion that
might arise later 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., earlier, timecode value.)
Note: 3Play assumes the external LTC signal matches session frame rate and timecode format. For
example, NTSC 29.97 and 59.97 sessions result in drop-frame timecode internally (all others are NDF).
Similarly, in a 24fps session LTC is treated as 24fps.
