Note: Do not mix sensor and settings slaves as this will cause inconsistencies in clip naming.
19.2 Genlock Synchronization
The camera's sensor and SDI outputs can be synchronized to a reference sync signal (a tri-level HD
signal or an analog black burst signal) using the SYNC IN BNC connector. The camera's sensor needs
to run at equal or double the frame rate of the reference signal to establish synchronization.
Activation of Genlock
1. Connect the genlock source to the cameras SYNC IN connector.
2. Ensure that the camera's sensor frame rate matches (or is double) the genlock source frame rate.
3. Set
MENU > System > Sensor > Genlock Sync to SYNC IN .
With Genlock Sync activated, the camera displays a genlock icon on the HOME screen
and in the status info of EVF/Monitor and the SDI outputs. The icon turns orange when
the camera can not synchronize to the genlock signal or if no signal could be detected.
In this case, see MENU > Alerts for detailed information.
Note: Simultaneous use of Timecode mode Jam-sync and Genlock is not supported.
Sync Shift
The Sync Shift option applies an offset to the genlock signal at the input. Minimum step size is 52 ns,
maximum possible correction is up to +/- 20 ms (= 384000 steps), depending on the sensor frame rate.
► Select
MENU > System > Sensor > Sync Shift
and apply the needed sync shift.
19.3 Timecode Synchronization
The camera's sensor and SDI outputs can be synchronized to a reference timecode signal using the 5-
pin TC connector. The camera's sensor needs to run at equal or double the frame rate of the reference
signal to establish synchronization.
Activation of Timecode Synchronization
1. Connect the timecode source to the cameras TC connector.
2. Ensure that the camera's sensor frame rate matches (or is double) the timecode source frame rate.
3. Set
MENU > System > Sensor > Genlock Sync to TC IN .
With Genlock Sync activated, the camera displays a genlock icon on the HOME screen
and in the status info of EVF/Monitor and the SDI outputs. The icon turns orange when
the camera can not synchronize to the genlock signal or if no signal could be detected.
In this case, see MENU > Alerts for detailed information.
Note: Simultaneous use of Timecode mode Jam-sync and Genlock is not supported.
