Adjustments and Settings for Recording: Setting Time Data
As a result of processing to convert the video captured by
the imaging devices from a progressive signal to an interlace
signal, video signal delays will occur in the camera.
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,
open the <TC/UB> screen from the MAIN OPERATION
page and set it in the TC VIDEO SYNCHRO item.
Set by referring to the connection example.
Example 3:
When the unit and an external device are
locked to the external time code generator,
which is connected externally, and when
simultaneous recording is made by using the
TC OUT output signals.
Note
In the 1080-23.98PsF or 1080-24PsF mode, set the
23.98PsF or 24PsF HD signal as the reference signal and
input a 24 frame time code to the TC IN input.
If the VTR is capable of recording the HD SDI time code, it is
possible to receive the time code output from the HD SDI A ·
B output, and synchronously record video with the time
code. In this case, it is not necessary to supply a time code
output signal to the VTR.
Example 4:
When the unit and an external device are locked to the
external time code generator and when several units of
the camera are connected in a cascade configuration.
