From broadcast XML to browser-ready VTT
TTML (and its DFXP / iTT profiles) is the XML caption format used by
broadcast and streaming pipelines. Converting TTML to WebVTT turns
each <p begin="…" end="…"> element into a browser-ready
VTT cue, so the captions play natively in HTML5 video.
The conversion runs 100% client-side — your file never leaves your device.
