SDI Frame Rate
The SDI frame rate determines the number of images that are output per second on the SDI output(s).
It should be set equal to the sensor frame rate. If the frame rate is lower than the sensor frame rate,
frame drops will occur. If it is higher, duplicate images will be output. The available SDI frame rates
depend on the selected SDI format.
► Select
MENU > Monitoring > SDI > SDI 1 Frame Rate to set the frame rate of the SDI 1 output.
► Select MENU > Monitoring > SDI > SDI 2 Frame Rate to set the frame rate of the SDI 2 output.
SDI 3G Level
For the 3G SDI formats, you can choose whether to use 3G level A or B. Refer to the instructions of
your connected devices to decide which 3G level to use.
► Select
MENU > Monitoring > SDI > SDI 1 3G Level to set the 3G level for the SDI 1 output.
► Select MENU > Monitoring > SDI > SDI 2 3G Level to set the 3G level for the SDI 2 output.
Hide Messages
User messages displayed as overlays on the monitoring outputs are primarily relevant for the camera

viewing. The camera offers the possibility to suppress all user messages on a selected SDI output.
► Select
MENU > Monitoring > SDI > SDI 1 Processing > Hide Messages to hide user messages on
the SDI 1 output.
► Select MENU > Monitoring > SDI > SDI 2 Processing > Hide Messages to hide user messages on
