Inputting External Synchronizing Signals (Genlock) - JVC Connected Cam GY-HC900CHU Instructions Manual

Inputting External
Synchronizing Signals
(Genlock)
A [GENLOCK] terminal is available on the side
0
of the camera recorder.
You can input synchronizing signals from
0
FS-790 (sold separately) or FS-900 (sold
separately) that is connected to the accessory
connection terminal (68 pins) on the rear of the
camera recorder.
SDI signals (digital signals) can be input from the
0
[HD/SD SDI IN] terminal.
Input external synchronizing signals from the
0
[GENLOCK] terminal and [HD/SD SDI IN]
terminal, and synchronize the camera video with
the external signal.
Input external synchronizing signals from the
0
[GENLOCK] terminal, and synchronize the
camera video with the external signal.
The H (Horizontal) Phase of the camera
0
recorder's video signals can be adjusted with
respect to the external synchronizing signals on
the [A/V Set] B [Video Set] B [Genlock Adjust]
screen.
(A P134 [ Genlock Adjust... ] )
Memo :
The genlock feature is only usable in the Camera
0
mode.

Inputting External Synchronizing Signals (Genlock)

GENLOCK
1 Set the camera recorder to the Camera
mode.
(A P20 [Operation Modes] )
2 Set [Genlock Input] to "GENLOCK".
Set [A/V Set] B [Video Set] B [Genlock Input] to
"GENLOCK".
(A P134 [ Genlock Input ] )
Memo :
Set to "Adapter" to input synchronizing signal
0
from the accessory connection terminal (68
pins) on the rear of this unit.
3 When in the standby or stop mode, input
synchronizing signals from the SYNC
signal generator to the [GENLOCK]
terminal.
When the camera recorder's video is locking
0
to the external synchronizing signal, "Sync
Locking" appears on the screen.
After locking to the external synchronizing
0
signal is complete, the display disappears
and recording can be performed.
If there is genlock signal input but the signal
0
format is not supported, "Invalid Sync" is
displayed.
Memo :
If the frame rate in [WFrame & Bit Rate]/
0
[YFrame & Bit Rate] in the [Record Format]
menu is set to "60p", "60i" or "30p", 59.94 Hz
synchronizing signals (vertical synchronization)
are input.
50 Hz/60 Hz synchronizing signals are not
synchronized.
If the frame rate of [WFrame & Bit Rate]/
0
[YFrame & Bit Rate] in the [Record Format]
menu is set to "50p", "50i", or "25p", 50 Hz
synchronizing signals (vertical synchronization)
are input.
59.94 Hz/60 Hz synchronizing signals are not
synchronized.
(A P152 [ W Frame Rate ] )
Do not connect or disconnect the input cable for
0
the synchronizing signals during recording or
playback
If the power is turned on during input of external
0
synchronizing signals, vertical oscillation may
occur. This is not a malfunction.
Signals such as VTR playback signals with
0
jitters may not be synchronized on this camera
recorder.
Only H (Horizontal) and V (Vertical) genlock
0
functions are available on this camera recorder.
It does not come with a lock function for SC (sub-
carrier). Color flash may occur during switching
such as when composite signals are used by a
switcher.
