CapMate is an innovative platform designed for the quality control and correction of captions and subtitles, which automatically detects various issues and enables users to make corrections and export the improved captions efficiently. It ensures that your captions or subtitles meet specific standards, including SCC, IMSC, and TTML, while also validating them for popular content delivery services such as Netflix, Amazon Prime, Disney+, and HBO, among others. This tool helps users identify synchronization problems and overlaps between captions and burnt-in text, offering both auto and manual correction options. Furthermore, it quickly highlights offensive or inappropriate language in captions and allows users to replace such words with alternatives of their choosing. CapMate also features an advanced browser-based interface for reviewing and correcting captions, making it easy to validate essential captioning parameters like Duration, Characters per line, Words per minute, and overlaps of successive captions, enabling users to maintain high-quality standards in a time- and cost-effective manner. By integrating these functionalities, CapMate simplifies the entire process of captioning, ensuring that content creators and distributors can focus more on their core activities while relying on effective solutions for caption accuracy.
