Synergy Series Operation Guide (v18) Background Transitions • 5–5
The function of the
ROLL VTR
button is determined by the Roll VTR Mode
setting (on the Personality Menu ):
~ If the Roll VTR Mode is set to
Play
, pressing
ROLL VTR
immediately plays
the serial device(s) selected in the transition area (one device per bus, including
device(s) from a re-entered MLE) on the MLE. Here, the button is
momentary .
The transition that brings on the device(s) is initiated manually with the fader,
automatically using
CUT
or
AUTO TRANS ,
or via an external editor.
~ If the Roll VTR Mode is set to
Arm
or
Armed Always
, pressing
ROLL
VTR
arms the switcher for a transition. When the transition is initiated by
pressing a crosspoint on the PGM bus, with the fader,
CUT
or
AUTO TRANS
,
or an external editor command, the device(s) (one device per bus, including
device(s) from a re-entered MLE) roll and are automatically taken to air
after
the preroll interval has elapsed. In Arm mode, the
ROLL VTR
button is
latching , and it remains latched until toggled off manually. In Armed Always
mode, the button is always latched; you must re-configure the button in the
Personality Menu or using a custom control macro.
To roll a serial controlled device, the following prerequisites must be met:
~ The device must be connected to the control panel remote port via RS-422 or
RS-232 serial communications.
~ The input “type” must be set to VTR, and the proper communications
parameters must be set (using the
Communications Menus ).
~ Depending upon the device(s), the VTR Remote Control Option , Video
Server Control Option or the Audio Server Control Option must be
installed as appropriate. Any combination of the three options can be installed.
~ The device must be chosen on the selected MLE — on any bus. Re-entry
selections are also permitted.
Refer to the section “ Clip Control Overview ” for detailed instructions on programming
and running VTR, Video Server and Audio Server clips.
• The
TRANS PV
(transition preview) button is located in the MLE Transition
group only . This function allows you to rehearse any preset-to-program transition
without affecting the selected MLE’s program output. Refer to the section
“
Transition Preview ” on page 5–15 for details.
• The
KEY OVER
button is located in the MLE Transition group only. This
function allows you to change the priority of the MLE’s Key 1 and Key 2 as a
transition, rather than as a cut. Refer to the section “ Key Over ” on page 5–17 for
details.
• The TRANS LIMIT button (located in the MLE Transition group only) allows you
to stop a transition at a preset position — in between the two absolute Fader limits.
Refer to the section “ Transition Limit ” on page 5–18 for details.
• The DISS button (located in both transition groups) selects a dissolve as the
transition type. When the dissolve is performed, the video on the PST bus gradually
mixes into the video on PGM . At the end of the transition, PST video completely
replaces PGM video, and the buses flip-flop. The DISS button is mutually
exclusive with the WIPE and DVE SEND buttons. Refer to the section “ Using
Dissolves ” on page 5–8 for instructions.
