composition:builder enables TV stations to easily create professional-looking real-time graphic templates for just:live and just:play.

Powerful Graphics Development

composition:builder enables you to create professionally looking real-time graphic templates for news, weather, stock exchange, sports, and other broadcast applications. These real-time graphics can directly be used in just:play and just:live.

Customize on Air

Customize your real-time 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

composition:builder 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.

Web-Based Graphics Control

Changes to graphics and information sources can be easily made during playout and brought to air in realtime – even with remote, web-based customized control interfaces that can be used with any web-browser (on desktop and mobile devices).


composition:builder is designed to interface with Apple’s Quartz Composer technology, enabling you to create your own custom components in Quartz Composer to extend your graphic templates.

Native Integration

composition:builder graphics 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.
