Working with XG Layers
Working with XG Layers
There are up to 8 XG layer accessible at your panel. Your panel can have some number of XG
layer buttons. You can choose XG clips in the XG layer sub-menu. You can also turn the layers on
and off in that menu.
XG layers are peculiar. First, XG layers are processed by one of the Imagestore 750’s DSKs. If you
are using XG layers, only 3 of the 4 DSKs are available to process keys.
Second, you cannot view an XG layer merely by selecting it on PST. Doing so only arms the XG
layer for transition. However, you can view XG layers by selecting XG layers on PGM and then
selecting the DSK that carries it, either on PGM or on PST. If you select the DSK on PGM, the XG
layer appears on air. If you select the DSK on PST, it does not.
The Imagestore 750 has several options that relate to this phenomenon and which affect the
way you work with that Imagestore 750. These are the options:
• ‘Slave keyer assign’.
This option designates one of the DSKs as the default carrier for XG layer content. When you
select an XG layer (on PST or PGM) the default DSK is also selected. You can always override
this default.
The option can also specify that none of the DSKs is the default. In this case, you must
choose a DSK carrier manually.
• ‘Slave keyer follow up’.
This option can be enabled or disabled. When it is enabled, the default DSK turns on auto-
matically when you have selected one or more XG layers.
When this option is disabled, the default DSK is not affected by XG layer selections.
Note that when this option is enabled and you select XG layers on PGM, the DSK is also
selected on PGM. Consequently, the XG layers appear on air. When this option is disabled
and you select XG layers on PGM, you can select a DSK on PST to view the XG layers.
• ‘Slave keyer follow down’.
This option can be enabled or disabled.
When it is enabled, the default DSK turns off automatically when no XG layers are selected.
When this option is disabled, the default DSK is not affected by XG layer selections.
Consult your system administrator to determine how your Imagestore 750s are configured.
Working with Voice-Overs
Imagestore 750s have two voice-over mixers: Over 1 and Over 2. The “layer” section of the
program and preset button rows can include 0, 1, or 2 voice-over buttons.
There are two parameters that govern the use of voice-overs: the “duck” level and the over level:
Both of these values are expressed in decibels (in the range –100.0 dB to +28.0 dB).
Each voice-over has its own set of levels.
