About this conversion
SSA is the older sibling of ASS, full of styling tags that browsers and HTML5 `<track>` elements don't understand. Converting to WebVTT gives you web-ready captions: styling is reduced to plain text and the timestamps are rewritten to VTT's `HH:MM:SS.mmm` format under a proper `WEBVTT` header.
