Using Genlock
The CamBar is able synchronise it’s cameras to an external genlock signal via the CamBar Sync cable on the CamBar loom.
This allows the CamBar to operate at specific framerates and to carefully control when the CamBar cameras are “exposing” to the environment. The chief benefit of this is to allow the system to operate in LED volumes where hidden LED markers are being utilised.
It is important to understand that using a Genlock signal is NOT required for typical usage and that using a Genlock signal will limit the possible exposure range of the CamBar which can be detrimental when working in poorly lit environments.
The CamBar will automatically utilise a Genlock signal when a compatible signal is connected to the CamBar Sync port on the CamBar loom (marked 7)
When using the Link, a genlock signal can be connected to the Link “SYNC IN” port.
When using the Origin, please connect a genlock signal directly to the CamBar loom using a standard BNC barrel.
If you do not wish to use a Genlock signal, then simply do not connect a genlock signal to the hardware.
The CamBar is compatible with all Tri-Level or Blackburst genlock signals between 23.98 and 60
The current genlock or “Sync” status of the CamBar can be seen in both the UI dashboard and via a status LED on the CamBar itself.
In the UI, the status of the Sync is displayed in the Sync section of the CamBar Panel
On the CamBar, the status LED on the rear of the device will display the following states:
- Blue full on: CamBar operating in 60fps mode
- Blue flashing: CamBar operating in 50fps mode
- Green flashing: CamBar is being controlled by an external Genlock signal (via the sync in)
- Green full on: CamBar in genlock mode but no genlock signal detected
- Unlit: CamBar is disconnected or defective
If a flashing Green LED is not displayed, then please confirm the signal pathway into the CamBar.
When using a genlock signal, the “Sync Offset” value becomes available. This parameter can be used to offset when the CamBar cameras are exposing to the environment. This can be useful when trying to perfectly synchronise the CamBar with hidden LED tracking markers.
If working in an LED environment with hidden tracking markers, and the markers are not visible or poorly visible, try adjusting the Sync Offset value until the hidden LED markers are clearly seen.
