EBU STL Viewer’s General Info:
STL Validation Module provides validation of the EBU STL subtitle file, according to the EBU “Specification of the EBU Subtitling data exchange format” – TECH 3264 specification. The validation process examines and validates the internal General Subtitle Information (GSI) block and all Text and Timing Information (TTI) blocks structure. The validation of a single EBU STL subtitle file takes only a few second, thus enabling the product for fast processing of big number of local or remote files.
Each EBU STL format check can be disabled or enabled or set to another report type, such as Info, Warning or Error. The solution can be applied in wide variety of workflows and with many container format deviations due to its flexibility and customization ability.
The validation report output can be exported into XML report file, containing the full report information in standard XML format. This allows easy integration of the solution with any digital media workflow and further processing of the report information with any third party systems.
The validation takes only a few seconds for an average long and complex media file to be processed.
