Setting the time code related switches
• Set the PRESET/REGEN switch to "PRESET".
• Set the REC/FREE switch.
REC : The data preset in the time code generator runs
only during recording.
Use this setting if it is required to record continual
time codes across different scenes.
* However, approximately ±1-frame variations may
occur in scene transition accuracy.
FREE : The time code starts to run from the time it is preset
in the time code generator.
n
Setting the VCR Setup Menu
• Set the VCR Setup Menu item No. 516 DISPLAY SELECT to
“TC”.
Select the time code generator's framing mode using the VCR
Setup Menu item No. 416 NON DROP/DROP.
DROP : The time code generator's running method is set
to the drop frame mode.
Use this setting when placing emphasis on the
recording time.
The “DF” indicator lights up on the display in the
drop-frame mode.
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.
In the NON DROP frame mode, the "NDF" indicator lights on
the display.
Drop frame/Non-drop frame mode
In the NTSC system, the actual number of frames per 1
second is approximately 29.97 frames, but the number of
frames that becomes the processing reference of the time
code is 30 frames. To compensate for this difference, the
mode called drop mode drops frame 00 and 01 for every
minute that cannot be divided by 10.
The non-drop frame mode is when no frames are dropped
and the actual time shift is neglected.
9-2 Presetting and Recording of Time Code
The GY-DV500 records SMPTE-standard time codes and user's bits. In the play or the record mode, the reproduced time codes or
user's bits are shown on the counter display.
• Time code data cannot be output through the unit's connectors.
The selected time codes can be shown on the counter display
during playback and recording as follows.
n
Set the VCR Setup Menu item No. 516 DISPLAY SELECT to
“TC”.
☞
See page 69.
n
Set the COUNTER switch to "TC" or "UB".
TC: Time codes are displayed.
UB: User's bit data of time codes are displayed.
9-1 Displaying Time Code
Note:
When the VCR Setup Menu item No. 398 SSF MODE is set
to CUE MODE or MARK MODE, the time code generator’s
running method is internally set to the REGEN mode.
When this is the case and you want to enter the preset
mode, set the VCR Setup Menu item No. 398 SSF MODE
to "OFF", or set the PRESET/REGEN switch to the
PRESET position again.
