Why convert SRT to WebVTT?
SRT is widely used for subtitle editing and distribution, while WebVTT was designed for captions and timed text on the web. HTML5 video elements and many browser-based players expect a VTT track rather than a raw SRT file.
Converting the file adds the required WEBVTT header and changes timestamp syntax without rewriting the spoken content, making an existing subtitle track ready for website and web-player workflows.
