Recording
Video recordings are made using the Channel 1 section of the graphic user interface, or with an
external automation system. Channel 1 can also be used for playback, when not recording.
Setting up to Record
The Image Server MAXX is used primarily in genlocked facilities. Both the server and video
sources feeding it are usually referenced to a common sync reference. This genlock signal
should conform to RS-170 specifications (composite video, black, with accurate sync timing
and amplitude ).
Several steps must be taken before making a recording on the Image Server:
1.
A genlock signal should be applied to the rear panel genlock connector. The input has a
fixed 75-ohm termination. Take care not to add another termination at any point on the
genlock cable. It is good practice to provide a direct feed from the genlock source or a
distribution amplifier, rather than “loop through” connections from other equipment.
2. The external genlock signal must be selected as the sync reference, using the On-Screen
user interface.
A. Eject any clip in Channel 1 and verify that the status window displays IDLE.
B. From the main menu bar select
CONFIGURE>SYSTEM
.
C. Select
GENLOCK
as the sync source.
D. Click APPLY followed by OK . The CONFIGURE window will close.
E. Check that the front panel
GENLOCK
LED is now illuminated.
Note: The
INTERNAL
sync reference setting (a crystal) can be used for recording only
when genlocked video output is not required. A genlock signal should be connected to
the video source, whenever possible.
3. The Image Server can accept a video signal at either its composite video input, or its serial
digital (SDI) input. Verify that the input to be used is currently active. This selection is
performed from the Configuration option on the Main Menu bar.
A. Select CONFIGURE > CHANNEL 1 .
B. On the Configuration screen select CVBS, SDI/Discrete Audio or SDI Embedded
Audio
as an input source.
C. Click on APPLY or OK to confirm the selection and close the window.
4. The Image Server can record either two or four audio tracks according to a selection made
in the Channel 1 Configuration window. When a selection is made it will be saved for
future recordings.
