Chapter 9 Other Useful Functions — Setting the time data
Retention of user bits in memory
User bit settings are automatically recorded and are retained even if the power is turned off.
Frame rate information
The relationship between frame rates, image pull-down, and time codes/user bits is as follows.
60i600
60P608
30P308
24P248
24PN24C
50i502
50P50A
25P25A
P 9
P 1
P D
P B

Setting the time code
1
Press the <TC> button to display the TC screen.
2
From the time code display, select [DF] or [NDF] in [DF/NDF].
Set [DF] to advance the time code in the drop frame mode, and set [NDF] to advance it in the non-drop frame mode. Note, however, that the time
code always runs in [NDF] in the 24p (23.98P) mode.
3
Select [SET].
The [TC SET] screen is displayed.
4
Set the time code using the jog dial button.
5
Press the jog dial button to confirm the time code setting value.
Settable time code range
59.94P, 29.97P 00:00:00:00 to 23:59:59:29
23.98P 00:00:00:00 to 23:59:59:23
50P, 25P 00:00:00:00 to 23:59:59:24

NOTE
t If you exit the time code setting screen without pressing the jog dial button, the set values will be disabled.
Time code function during battery replacement
Even during battery replacement, the backup mechanism functions, allowing the time code generator to continue operating.
When each item of the system mode has been changed, the time code of free run may shift. Turn on the power again, check the time code, and reset it,
if necessary.
Time codes in variable frame rate
fIn 24PN, recording is 24 frames, output is 30 frames, which matches 2:3 pull-down images.
fThe advance rate of the recording and output time code matches real time only when the image frame rate is 24P. When 60P, recording advance rate
is 60/24 times. In this case, the camera switches to [REC RUN] xed operation and the time code value that is output when recording starts matches
the recording time code.
fIt is the same when shooting in modes other than 30P when in 30PN and shooting in modes other than 25P when in 25PN.
Externally locking the time code
The internal time code generator of the camera can be locked to an external generator.
Example of connections for external locking
As shown in the gure, connect both the reference video signal and the reference time code.
