Start delay
The Start delay option sets the delay in μs for the camera system. When enabled the camera system will delay the start in relation to the time that the master camera receives the start command from QTM. This delay is required on the Main system in a multiple video system setup.
The default start delay is 40000 μs and is needed to make sure that all of the cameras in the system receives the start time from the master camera.
The Start delay option is not in use if the cameras are synchronized with an external timebase.
