Recording from a variable frame rate camera

Recording the HD SDI output signal from
a variable frame rate camera
Connect the HD SDI (720/30Pover 59.94P) output of the
variable frame rate camera to the HD SDI input connector of
this unit.
1
Select "SLTC" in menu No. 032 REC REF.
Detect the frame information from the superimposed
time code in the HD SDI signal to prevent displacement
of the field.
2
Adjust the following settings to activate the two settings.
Menu No. 25 SYSTEM FREQ: 59/60
Menu No. 020 SYS FORMAT: 720p
INPUT SELECT button on the front panel: HDSDI
3
Change the mode for this unit to REC PAUSE mode.
4
Press the PAUSE button while confirming the HD SDI
output image of the variable frame rate camera to start
recording.
The time code is recorded to maintain the continuity of
the recorded tape.
The superimposed user bits for the HD SDI signal is
recorded.
<Note>
Through the settings in menu No. 032 REC REF, the time
code and the user bits recorded on the tape are as follows.
SLTC:
The time code is recorded to maintain the continuity of
the recorded tape.
The superimposed user bits for the HD SDI signal is
recorded.
The following settings are then invalid.
TCG switch on the front panel
(REGEN/PRESET/EXT)
Menu No. 503 TCG_MODE
(SW/AUTO)
Menu No. 505 TCG_REGEN
(TC&UB/TC/UB)
Menu No. 507 TC_SOURCE
(EXT_L/SLTC/SVITC)
NORMAL:
Time code and user bits are recorded according to the
following settings.
TCG switch on the front panel
(REGEN/PRESET/EXT)
Menu No. 503 TCG_MODE
(SW/AUTO)
Menu No. 505 TCG_REGEN

Field displacement

There is no discriminant information to differentiate between
the first field and the second field in the HD SDI signal of
720P. Accordingly, it is usually necessary to synchronize the
HD SDI signal transmission equipment to the recording
equipment with the reference signal from SD. If not
synchronized, there is a risk of generating displacement
(image frame fails to match the time code) with 1/2
probability described as follows.

from a variable frame rate camera (720/30P over 59.94p)
with this unit.
