Features

Graphics Co-Processors

File > Save As > To Device...

and specify the file name (

‹macro preset filename›.xml

).

Next, adjust the Imagestore 750’s active configuration to make use of the newly created macro
preset file. In the drop-down list at the top right corner of the Imagestore 750 Configurator,
select ‘Configuration Mode’. Re-load the active configuration if required (File > Open >
F

rom Device... > Active Configuration

).

Under the ‘System Settings’ tab, choose:

Miscellaneous > Macro

Select the newly created macro preset file name from the ‘macro preset file’ list box and then
save and apply the updated configuration file (

File > Save and Apply Configuration

). After the

Imagestore 750 has restarted, all macros within the selected macro preset file will be available
for use.

Triggering Macros

You can trigger macros directly in these ways:

At the front panel using Operate > Trigger Macro.

Setting a GPI input to trigger a macro. (See

GPI Inputs and Macros

on page 48.)

Through automation.

Through an iMC control panel (if the Imagestore 750 has the master control option).

Graphics Co-Processors

The Imagestore 750 can be configured for use with Miranda’s Intuition XG (a single-channel
advanced HD/SD graphics co-processor).

The Intuition XG can be regarded as a co-processor. It can generate complex output incorpo-
rating multiple objects (animations, clips, images, and text) on numerous “virtual” keying layers.
These scenes can then be composited into one signal that is fed into the Imagestore 750
through the fill and key inputs and keyed as a ‘Load Live’ signal on any of the available keying
layers. When this signal includes embedded audio, it can provide background audio or voice-
over input to the Imagestore 750.

An Imagestore 750 with an Intuition XG co-processor is often called a “channel” or “channel
processor” because it collectively manages all of the video signals, effects, graphics and audio
processing that are output from the Imagestore 750.

When such a “channel” is being driven by Oxtel-protocol automation, it is generally recom-
mended that the Imagestore 750 and Intuition XG co-processor to be controlled from
independent serial automation links. However, the Imagestore 750 can also be placed in a mode
where it receives all commands on a single automation link and then forwards selected layer-
based commands to the Intuition XG co-processor over a serial or network link. This is described
in more detail under Oxtel Command Forwarding to a Co-Processor, following.

When such a “channel” is being driven by Presmaster-protocol automation, there is only one
serial link from automation to the Imagestore 750. Any automation commands intended for the
Intuition XG co-processor are sent as “pass-through” commands.
