Powerful Graphics Development
The Composition Builder application enables you to create professionally looking realtime graphic templates for news, weather, stock exchange, sports, and other broadcast applications. These realtime graphics can directly be used in just:play and just:live.
Customize on Air
Customize your realtime graphics On Air or use external sources (XML, RSS, images, and text files) to update your graphics manually or automatically.
We love XML. And XPath.
Out-of-the-box support for XML files, coupled with the powerful XPath query language enables data extraction from local or networked files.
Sample Content Included
The Composition Builder application ships with a package of pre-designed templates that can be used and modified for free. Drop them into any graphics layer in just:play or just:live to play them out concurrently with any video clip.
Stop Frames for Dynamic Graphics
The powerful “stop-frame” functionality allows you to dynamically extend the duration of graphic templates while maintaining the individual duration of animations within the template.
Live Graphics Control
Changes to graphics and information sources can be easily made during playout and taken to air in realtime, enabling fast turnaround on-air adaptations where needed.
Extensibility
The Composition Builder application is designed to enable fast creation of your own custom template compositions to extend your graphic templates portfolio.
Native Integration
Realtime graphics created with the Composition Builder application are interpreted natively and rendered on the fly by ToolsOnAir’s playout engine, allowing for a real-time preview of graphic templates in the just:play and just:live user interface.
