GENLOCK
Generator locking (genlock) is a tri-level signal used to synchronize video and audio systems. Genlock is based on
SMPTE 296M and 274M.
There are two (2) important genlock sync modes:
Monitor Sync
Sensor Sync
NOTE:
For genlock to function correctly, the cameras must be on the same firmware version, and must be using the
same project time base and recording frame rate.
MONITOR SYNC
Monitor Sync occurs when a genlock signal is provided that is compatible with the current monitor output frequency.
Monitor Sync is achievable even if the camera is using another form of synchronization to sync the camera sensor.
1. Connect the genlock device to the camera:
Connect the
SYNC
port on the camera to the device (green BNC) using a 3BNC-to-00 LEMO Sync Cable.
2. Go to

.
3. Select
BRAIN HDSDI
from the drop-down menu.
4. Select the desired monitor output frequency from the
Frequency
drop-down menu. Select
Auto
to automatically
match the HD-SDI output to the current Project Time Base.
Monitor Sync is achieved automatically when a genlock signal is provided that is compatible with the current
monitor output frequency. When Monitor Sync is achieved, the
GEN
indicator in the Lower Status Row illuminates
green.
