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.

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.
