Timecode
The UMC-4 can sync to an external LTC timecode. The precise crystal
oscillator in the UMC-4 will count accurately with +/- 1 ppm stability. It is
recommended to jam-sync after every shooting break to avoid the risk of
losing timecode sync during a shot.
The Timecode menu allows the setup and display of timecode. Timecode is
recorded with the metadata onto SD card and can be used to synchronize
metadata with the images in postproduction.
Select Show in Home Screen to switch the timecode display in the info
area of the Home screen on and off.
Select Frame Rate to change the time base (23.97, 24, 25, 29.97,
29.97DF, 30, 30DF).
Select Jam to change the jam sync mode:
• Off: Jam sync is not active. The UMC-4 continuously generates
timecode itself and functions as a timecode master clock.
• Once: The UMC-4 synchronizes its timecode with the external LTC
source and continues counting on its own. After synchronization, a
pop-up will appear to indicate the operation was performed.
• Cont.: The UMC-4 continuously reads the LTC-timecode signal at
the TC connector as long as it is present. Upon disconnection or
loss of signal, the UMC-4 continues counting on its own. When the
external signal is reconnected, the UMC-4 uses the values of the
external signal again.
Select Set Timecode to set the timecode. Use the arrow soft buttons to
navigate the timecode values. Press the OK soft button to set the
timecode. Press the CANCEL soft button to cancel the timecode setting.
Press the SHOW soft button to display the current timecode. Press any soft
button to return to the menu.
Note: It is recommended to jam-sync after every shooting break to avoid
the risk of losing timecode sync during a shot.
Note: The UMC-4 will keep its timecode for at least 30 minutes, even after
disconnection from the power source or if it is switched off.
