the equivalent preview keyer follows program. If a keyer is then armed, the preview keyer shows
the transition state that will occur on program after the next “Take” transition.
Note: Keyers can be armed for cuts or fades from a Miranda iMC panel, an RCP-BR / Xpanel or
through Presmaster automation. This table shows how active preview keyers are driven based
on the equivalent program keyer position and arm state:
You can set this option in the Imagestore 750 Configurator using Video > Preview >
Preview Keyer Position > Active Preview Keyers,
or at the front panel
(Setup > Miscellaneous > Active Preview).
When ‘Active Preview Keyers’ is disabled, the keyers on preview are controlled independently of
the program keyers and their arm states. Preview keyers are normally configured and remain in
the ‘keyer up’ position in the Imagestore 750 Configurator (Video > Preview > Preview
Keyer Position > DSK x Preview Keyer Position ).
