of the screen size can be animated
for just over half a minute. Larger screen sizes or smaller playout memory sizes affect the
maximum animation duration pro rata. This table shows the duration for animations at 1080i.

MB:
The animation’s load time (into storage) depends on the total size of the animation file.

.oxa
animation files using one of the following applications:
•
Xplorer
•

Plug-in (available on the MCS CD)
Component images can also be imported into the animation builder from 32-bit Targa image
files, allowing components to originate from almost any computer graphics system.
Easytext
Easytext requires the IS-750-ET option.
CG text effects, including static text and simple crawls, are defined in
.oxa
Easytext files, or
templates. The templates can comprise many text and image elements, all of which can be
updated dynamically through automation. Data sources can also be defined within text
elements to help achieve dynamic data-driven updates including timers, date, stopwatch,
countdown, and custom data.
You can generate
.oxa
Easytext files using one of the following applications:
•
XStudioLT.
•
TextBuilder2 (available on the MCS CD).
Bugclocks
“Bugclocks” require the IS-750-Clock option.
Analog or digital clocks are defined within
.oxa
Bugclock files. The Bugclock file defines the
properties of the clock, such as hand and face styles, and whether it shows hours, minutes, and
seconds. Digital clocks can be 12 or 24 hour style. A bugclock can be locked to a station’s LTC or
VITC timecode. Clocks are loaded, previewed, positioned, keyed and controlled through GPIs
and automation, as are animations and static logos.
