Snapshots
What are Snapshots?
The term “snapshot” refers to a function whereby the
various settings required to apply a particular effect to an
image are saved in memory as a set of data, for recall as
required, to recover the original state.
Snapshot operations use the Flexi Pad control block.
Snapshot types
There are two types of snapshot: those called simply
“snapshot,” and effect snapshots. They differ in the types
of data saved and the save destination registers (memory
locations for saving data).
Snapshots
These are sets of data saved for each region (functional
unit block) to enable recall of video states.
Note
In this version, PGM/PST and MISC data cannot be saved
and recalled individually.
Effect snapshots
These are sets of data saved to enable recall of M/E effect
settings and PGM/PST wipe settings.
Snapshot attributes
Temporary attributes
When a snapshot is recalled, you can specify up to four
additional attributes called “temporary attributes.” They
are as follows.
Cross-point hold: When the snapshot is recalled, the
cross-point button selection remains unchanged.
1)
The same setting is used for both A and B buses. Also,
the same setting is used for both PGM and PST buses.
Key disable: When the snapshot is recalled, the key
settings (including key on/off states, if specified by
setup settings) remain unchanged.
1)
This can be set
independently for each keyer.
Effect dissolve: The transition from the state before the
snapshot recall to the snapshot settings is carried out
smoothly, by a dissolve.
Auto transition: An auto transition starts the instant the
snapshot is recalled. The auto transition setting is valid
for M/E and PGM/PST.
1) There are three hold modes for key buses: Xpt Hold, Key Disable, and Key
Disable with Status. Select one of the modes with the setup menu. See
page 173.
Usable temporary attributes
The following table shows the temporary attributes which
can be used in each region.
Bus override
Even when the setting of the temporary attribute “cross-
point hold” is off, you can recall a snapshot while
maintaining the current cross-point selection. This
function is called “bus override.”
On how to use the bus override function, see page 126.
