PREPARATIONS FOR OPERATION
Presetting and Recording
of Time Code
The time codes from the internal time code generator can be
recorded at the time of recording scenes.
• The TC/UB/CLOCK menu screen differs depending on
whether the FRAME RATE item on the VIDEO FORMAT
menu screen is "60/30" or "50/25".
There are two ways to preset the time code.
• Set from the TC/UB/CLOCK menu screen.
• Set in the LCD screen without opening the menu screen.
This section explains how to set from the TC/UB/CLOCK
menu screen.
* See page 46 for instructions of setting from the LCD
screen.
Menu and switch settings to set the time code preset are the
same as the settings below.

tions may occur in scene accuracy.
FREE : The time code starts to run from the time it is
preset in the time code generator.

MEMO
Drop frame/Non-drop frame mode
In the NTSC system, the actual number of frames per 1
second is approximately 29.97 frames, but per time code
30 frames are processed. To compensate for this differ-
ence, the mode called "drop mode" drops frame 00 and 01
for every minute not divisible by 10.
The "non-drop frame mode" is when no frames are dropped
and the actual time shift neglected.
