CasparCG
CasparCG Server is versatile software compatible with both Windows and Linux, designed for professional graphics, audio, and video playout across multiple outputs. This powerful open-source solution has been in 24/7 broadcast production since 2006.
Exporting
When exporting templates for CasparCG, Loopic generates a single .html graphic template file. To incorporate it into CasparCG, you can either designate CasparCG's templates directory during the export process or manually transfer the HTML file to that directory. To activate templates, you can execute AMCP commands directly from the console or employ CasparCG client applications with user interfaces, such as the CasparCG Client.
Graphics Data Definition
CasparCG functions as a server application and lacks inherent knowledge of template definitions beyond the methods available for controlling template playback.
The Graphics Data Definition (referred to as "GDD") comprises a specialized collection of JSON-schema definitions tailored exclusively for dynamic TV graphic templates, and it is integrated into certain CasparCG client applications. All templates exported from Loopic include embedded GDD schemas.
Presently, Loopic generates GDD fields specifically tailored for Text and Image loader elements. Moreover, both these elements offer customizable properties accessible through the Settings panel.
