 TC/UB SET HDV/DV IN TC 

Selects whether to record internal time code or external time code while the unit records 
signals input from the 

HDV/DV jack.

BINTERNAL : Records the time code generated by the internal time code generator. (If 

[TC MAKE] is set to [REGENERATE] and no time code is recorded on the 
tape, the unit records time code from 00:00:00:00. If there is time code 
already recorded on the tape, the unit records continuous time code from 
this point.)

EXTERNAL : Records the time code with video and audio signals input from the 

HDV/

DV jack.

• Bars (– –:– –:– –:– –) are recorded as the time code if you start recording when this item is 

set to [EXTERNAL], the INPUT SELECT switch on the front panel is set to HDV/DV, and no 
signal is input via the 

HDV/DV jack.

When any signals are input, the time code of the signals is recorded.

• If you set this item to [EXTERNAL] and the external time code input is discontinuous or 

does not advance correctly, recording or displaying of the time code on the unit may not be 
done correctly. If there is a discontinuous time code on your recorded tape, you may not be 
able to edit or search correctly, depending on the device used to edit.

TC RUN 
(page 54)

Selects the advancement mode (counting up).

BREC RUN :

Time code value advances only while recording.

FREE RUN : Time code value advances even when the unit is not recording. (Use this 

setting to adjust the initial value of the time code to the present time.)

• To record the time code according to the setting of [TC RUN], set [TC MAKE] to [PRESET] 

• If you set the advancement mode to [FREE RUN], the time code will be updated by the 

internal clock when the power is off. Therefore, when you turn on the unit again, the time 
code may be somewhat off.

• If the internal backup battery is exhausted, the time code of the [FREE RUN] setting is 

initialized.

TC MAKE
(page 54)

Selects the time code when you start recording.

BREGENERATE :The time code value is set to continuous time code from the one already 

recorded on the tape. If no time code is recorded on the tape, it starts 
from 00:00:00:00.

The time code starts from the value set in [TC PRESET] in the [TC/UB 
SET] menu.

TC FORMAT 
(page 55)

Selects the recording mode of the time code when 60i format is used.

BAUTO :

Automatically sets the mode in accordance with the mode already set on a 
cassette tape. (If nothing is recorded on the tape, the non-drop frame mode 
is set. If the unit cannot correctly read the frame mode on the tape, it will 
use the frame mode that was set in the last position on the tape that the 
unit can read correctly. If you remove the cassette, the mode of the last 
position that the unit was able to read correctly is cleared and the non-drop 
frame mode is set when recording is restarted from the same position. If 
[TC MAKE] is set to [PRESET], the non-drop frame mode is set.)

Selects the drop frame mode.

Selects the non-drop frame mode.

When [60i/50i SEL] is set to [50i], the unit operates as a 50i specification model. Therefore, 
the time code is set to the non-drop frame mode. Even if 60i signals are input via an i.LINK 
connection when [60i/50i SEL] is set to [50i], the time code generated by the unit is in the 
non-drop frame mode regardless of the [TC FORMAT] setting. To set the time code to the 
drop frame mode, set [60i/50i SEL] to [60i]. As a result, [TC FORMAT] setting will return to 
the status before the [60i/50i SEL] menu was set to [50i].
