PREPARATIONS FOR OPERATION
Recording Time Codes in Continuation of Time Codes Recorded on Tape
The GY-HD100 also incorporates a time code reader. There-
fore, when the unit enters record mode from record-standby
mode, it can read the time code data recorded on the tape
and record time codes in continuation of the existing data.
The recorded user’s bit data are identical to the user’s bit data
recorded on tape.
* However, approximately ±1-frame variations may occur in
scene accuracy.
To enable this function, set the time code related switches as
follows before starting recording.
„
Setting
Set the TC GENE. switch inside the LCD door to REGEN.
MEMO
The time code framing mode automatically becomes the
mode (drop frame or non drop frame) already recorded on
the tape.
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”.
To preset the Time Code, make the following settings.
„ TC GENE. switch
Set to REC or FREE.
„ TC/UB/CLOCK menu screen (FRAME RATE: 60/30)
Use the DROP/NON DROP item to select the framing
mode for the time code generator.
MEMO
Drop frame/Non-drop frame mode
In the NTSC system, the actual number of frames per 1 sec-
ond is approximately 29.97 frames, but per time code 30
frames are processed. To compensate for this difference,
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.
„ TC/UB/CLOCK menu screen (FRAME RATE: 50/25)
Whether or not user’s bit data should be recorded can be
selected with the UB REC item on the TC/UB/CLOCK
menu screen.

REC : The data preset in the time code generator
runs only during recording.
Use this setting if it is necessary to record
continual time codes across different scenes.
* However, approximately ±1-frame varia-
tions may occur in scene accuracy.
FREE : The time code starts to run from the time it is
preset in the time code generator.
DROP : The time code generator’s running method is
set the drop frame mode.
Use this setting when placing emphasis on
the recording time.
NON
DROP : The time code generator’s running method is
set to the non drop frame mode.
Use this setting when placing emphasis on
the number of frames.
