Note that the angled brackets are required. Below is an example of using a device with the existing KSZ
(Keyframe Size) command:
KSZ 800 <DVCE0:PVW>
In the example above, the layer ID evaluated from the device Index 0 preview bus will be set to a keyframe HSize
of 800 pixels.
Understanding Registers
Registers provide an abstraction layer from specific data types with Spyder. Common data types such as
sources, stills, command keys, and treatments all have corresponding registers. In the Vista software interfaces
such as Vista Basic and Vista Advanced, all lists are sorted and displayed using the register lists, which allow
users to organize the way their data is displayed without changing the underlying data.
In the following figure displays a command key list in Vista Advanced containing a single command key named
‘Look 1’. The number 4 is displayed in the top -left corner of the command key, denoting that the register ID for
this command key is 4. Notice in the property panel to the right of the command key panel that the Command
Key’s data ID is 10. The ‘Recall Script Cue’ (RSC) command allows command keys to be recalled externally using
either the register ID (4) or the command key script ID (10).
Figure 49
In the following figure the user has moved the ‘Look 1’ command key’s position in the command key list. Notice
that the register ID has changed to 5, but the command key’s script ID has not change d. Recalling a script cue
externally now using the register ID would require sending an ID of 5 instead of 4 to recall the ‘Look 1’ command
key.
