– 105 –Chapter 4 Shooting — Setting the time dataExternal lock operation procedureTo externally lock the time code, follow the steps below.1 Set [FREE RUN] in the main menu → [RECORDING SETUP] → [TCG].2 Display TC with the button.3 Input a reference time code and reference video signal that are in a phase relationship (that conforms to time code specifications)to the terminal and the terminal.The built-in time code generator is locked to the reference time code. When approximately ten seconds has elapsed after locking, the external lockstatus will be held even if the reference time code from the external device is disconnected.f When the input reference signal of generator lock is disrupted, recording cannot be performed normally. [TEMPORARY PAUSE IRREGULAR SIG]is displayed in the viewfinder screen, and the clip is divided. The continuity of the time code is not guaranteed. Recording resumes when the signalreturns to normal. However, during loop recording, recording does not resume.f When the time code is externally locked, the time code is instantaneously locked to the external time code, the same value as the value of theexternal time code is output to the counter display area. Do not set to the recording mode for several seconds until the sync generator hasstabilized. Furthermore, lock the time code to the terminal signal.f When using the camera with [ON] set in the main menu → [RECORDING SETUP] → [PRE REC], disrupted images or stopped time codes maybe recorded if the time code is switched from recording run to free run immediately before recording or an external time code is input to be slave-locked to the terminal.f If you execute the slave once, even if there is no longer terminal and terminal input, the slave status ismaintained. However, in the following cases, the slave status will be released.- When [TC PRESET] is executed- When the power is turned off- When switching between [DF]/[NDF] in [DF MODE]- When [TCG] is set to [REC RUN]- When switching between [REC FORMAT] and [CAMERA MODE]Setting of user bits when the time code is externally lockedTo lock user bits to the input values from an external source, set [EXT] in the main menu → [RECORDING SETUP] → [UBG MODE]. Regardless of thesetting of [REC RUN]/[FREE RUN], it is slaved to user bits values input to the terminal.Canceling the external lockSet [REC RUN] in the main menu → [RECORDING SETUP] → [TCG] after stopping supply of the external time code.Cautions when switching the power supply from the battery to the AC adaptor while an external lock is activeTo keep continuously on the power supply of the time code generator, connect the AC adaptor to the terminal and then remove the batterypack. If the battery pack is removed first, there is no guarantee that the time code will stay externally locked.External synchronization of the camera unit while an external lock is activeWhile an external lock is active, the genlock is activated on the camera unit by the reference video signal input to the terminal.@@ NOTEt To externally lock multiple units with the camera as the master device, set to the same setting as on the camera. Note that in a system using a mixtureof interlaced and progressive scanning, the continuity of the video and time codes is not guaranteed.t When the external lock is applied to 24PN Native, be sure to input non-drop frame time code. External lock is not available in drop frame. Also, at themoment external lock is applied, the image may look corrupted. This is an operation to match the 5-frame cycle and is not a malfunction.Supplying the time code externallyYou can supply the output time codes to a VTR or other recording device from the camera by matching the camera images or the replayed images. terminal terminal or terminalVIDEO IN terminalSDI IN terminalHD SDI IN terminalTC IN terminalVTR, etc.1 Set [VIDEO OUT] in the main menu → [OUTPUT SEL] → [TC OUTPUT REF].2 Set [HD SDI] or [COMPOSITE] in the main menu → [OTHER FUNCTIONS] → [GL PHASE] to match the supplied video output.
