406 Zodiak User Manual
Section 5 — System Operation
Clip and Still Caching
Loading a clip or still will automatically cache it, if necessary. However,
you will want to be sure all the material you need for a show is cached in
advance, to permit immediate access to the material. Material can be
cached in a variety of ways:
• Load the item to a Still Store Preset or Program output using the Still
Store menu (see
page 405 ).
• Load the item to a Still Store output using the Machine Control sub-
panel (see
page 406 ).
• If you created E-MEMs specifying Still Store material, recall and run
these E-MEMs before the show (see
page 408 ). An effect may not run
correctly the first time if the Still Store material was not cached, but
running the E-MEM in advance initiates cache operations that will
make the material instantly available later.
Note When the cache is full, loading new material will cause existing cached mate-
rial to be overwritten. Generally the oldest material cached will be the first
material overwritten.
When an output channel is involved in a disk file transfer that channel is
not available for use, and only one disk file transfer is supported at a time.
The other Still Store output channels remain available during a transfer,
however, and can be used to access and display any currently cached mate-
rial.
Once material is cached, it remains available even if the current folder is
changed (the items will be shaded). Once an item originating from a dif-
ferent folder becomes uncached, however, it becomes inaccessible until the
folder in which that item resides is accessed again.
Machine Control
Zodiak Still Store stills and clips can be loaded to Still Store outputs and
played using the External Devices Control menu.
Duplicating a Still Store Item
A Still Store item loaded to a Still Store output cannot be saved directly as
a different Still Store item. However, a Still Store output can be fed as an
input to a different Still Store channel and then be captured or recorded and
saved, to duplicate the original item. Choose a different folder location or
a new name when saving the new item, to prevent overwriting the original
item.
Crop, position, and freeze options set on the output Still Store channel
feeding the Still Store input are incorporated into the image itself with this
technique, and so they will not be adjustable later. Because the images are
digital there should be no degradation of image quality.
