About this conversion
MicroDVD `.sub` files are frame-based (`{startFrame}{endFrame}`), which browsers can't use at all. Converting to WebVTT turns the frame ranges into real `HH:MM:SS.mmm` timestamps under a `WEBVTT` header so the captions play in HTML5 video. (v1 assumes ~23.976 fps; a frame-rate picker is on the roadmap for mismatched sources.)
