Locking the Timecode to Other Devices
Set the unit that supplies the timecode to a mode in which the timecode output keeps running (such as Free Run or Clock).
Note
Check that the supplied reference timecode and the reference video signal are in a phase relationship that complies with the SMPTE
timecode standard.
When operating with external lock, the timecode instantly acquires lock with the external timecode and the external timecode value
appears in the time data display area. However, do not start recording immediately. Wait for a few seconds until the timecode
generator stabilizes before recording.
If the frequency of the reference video signal and the frame frequency on the unit are not the same, lock cannot be acquired and the
unit will not operate properly. If this occurs, the timecode will not acquire successful lock with the external timecode.
If the external timecode source is disconnected, the timecode may shift by one frame per hour with respect to the reference timecode.
To release external lock
Change the [TC/Media] – [Timecode] setting in the camera menu.
External synchronization is also released if the system frequency is changed and when you start recording in a special
recording mode (Slow & Quick Motion).
