Adjustments and Settings for Recording : Setting Time Data
The unit’s internal time code generator can be locked to an
external generator. In addition, the external time code
generator can be locked to the unit’s internal generator.
As the figure shows, connect both the reference video signal
and reference time code.
For more information about the reference video signal and
GENLOCK, see [Setting External Reference Signal and
GENLOCK] (page 61).
Example 1: When locking onto an external signal
Example 2: When connecting a multiple number of units
and using one of them as the reference unit
Note
If you make a system with more than one unit, use the same
settings for all cameras for input and output. When different
settings are mixed, the image timing will not match.
In the unit, there is a video signal delay in the camera, which
is required or the process of converting video images taken
with the image-shooting element from the progressive
signals to the interlace signals. Since time is required for
making the 2:3 pull-down from the 24P frame, there is a
video signal delay in the camera. When recording from a
device that can record images without a delay and the unit is
connected in parallel, it is necessary to synchronize the time
code. To set this timing, set it in the TC VIDEO SYNCHRO
item. The menu item TC VIDEO SYNCHRO is found in the
<TC UB> screen on the MAIN OPERATION page.
Set by referring to the connection example.
Setting of the TC VIDEO SYNCHRO item
Note
This setting is enabled during progressive shooting (when
CAMERA MODE is 24P, 30P, 25P), and when the Scan Reverse
function is operating. This setting is unnecessary during
normal recording (when CAMERA MODE is 60i, 50i).

For setting to correct the time code
according to the delay of video signals.
0: Do not correct.
1: To delay the time code to be input
according to the timing of the
video images.
2: To forward the time code to be
output according to the timing of
the video images.
3: To delay the time code to be input
and forward the time code to be
output, respectively, according to
the timing of the video images.
