Snapshot Attributes
An individual snapshot may also have attached special conditions relating to
switcher or DME operation when the snapshot is recalled.
These conditions are called “attributes” of the snapshot, and can be added when
the snapshot is saved or recalled.
Types of attribute
There are five snapshot attributes, as follows.
Cross-point hold: When the snapshot is recalled, the cross-point button
selection remains unchanged. This can be set independently for each bus.
Key disable: When the snapshot is recalled, the key settings remain
unchanged. This can be set independently for each keyer. A Setup menu
allows you to select whether or not the key on/off state should also remain
unchanged.
For details of the setting operation, see “Settings Relating to Keys, Wipes
and Frame Memory (Key/Wipe/FM/CCR Menu)” in the Chapter 16
(Volume 2).
Effect dissolve: The transition from the state before the snapshot recall to the
snapshot settings is carried out smoothly, by a dissolve. The dissolve
duration can be set in the Snapshot menu.
Auto transition: An auto transition starts the instant the snapshot is recalled.
The auto transition setting is valid only for M/E-1, M/E-2, M/E-3, and
PGM/PST.
Note
If both effect dissolve and auto transition are selected as attributes, the auto
transition takes precedence.
GPI output: A GPI output is sent to the allocated GPI port the instant the
snapshot is recalled.
The trigger type depends on the switcher GPI output settings made in the
Setup menu.
For details, see “Interfacing With External Devices (Device Interface
Menu)” under “Setup Relating to Switcher Processor” in Chapter 16
(Volume 2).
Clip event: Recall a frame memory clip immediately after the snapshot is
recalled.
