4x ISO (Switching 4x3G SDI) mode
When the device is set to Switching 4x3G SDI mode, you can connect up to four separate
1080p60 signals to the SDI inputs for switching between those inputs to create one video
output. This means that you can do a multicamera production where you can easily switch
between multiple camera angles, as well as pre-recorded content and presentations that
are running on a computer. These types of productions are common for recordings of live
events, or any scenario where it would be beneficial to switch between multiple cameras
or sources.
All inputs MUST have an identical frame rate and resolution. For example, 59.94p, 29.97p
and 23.98p, cannot be mixed with 60p and 24p.
SDI input 1 is the master input and needs to have a constant signal connected in order to
derive sync for all of the other inputs. Therefore it is important that the SDI cable is prop-
erly connected to SDI 1 to ensure that the signal is locked. A loose connection may cause
synchronization issues with the other inputs.
The 3G-SDI output standard on connected cameras should be set to level A. 3G-SDI
inputs using Level B in dual stream or BL may not be supported. If level A is not available
on a connected camera, the frame rate must be set to a maximum of 1080p25/29.97/30.
