1.7 Time code applications
1.7.1 Single Viper-Venom configuration
Only one Viper plus Venom is being used. A real time clock is available inside the
Venom. This clock is used to creat the SMPTE time code. The clock can be adjusted in
the menu on the LCD screen.
1.7.2 Multiple Viper-Venom configuration with single Clock-It box
In this configuration, more than one Viper-Venom combination is used. In this case, the
method mentioned above is not accurate enough. An external master clock is needed
to synchronize the time codes of the Venom recorders. The diagram below shows the
mechanism that is available:
A Clock-It box is connected to the first camera system containing a Viper and a Venom
recorder. Both the Clock-It box and the Venom docking plate receive a genlock signal
on their reference input. The Clock-It box outputs the time code (according to SMPTE
266M standard) to the Venom via a connector on the docking plate. In this way the
Venom takes over the the time code of the Clock-It box.
The LTC input is removed and connected to the docking plate of the next camera
system and this one takes over the time code of the Click-It box. The Venoms in system
1 and system 2 are now running with the same time code. In this way the time code
can be synchronized in a multiple camera environment.
