Web captions → broadcast XML
DFXP (Distribution Format Exchange Profile / TTML) is the XML
caption format used in broadcast and enterprise delivery.
Converting VTT to DFXP maps each WebVTT cue into a <p begin="…" end="…"> element so your web
captions work in broadcast-ready pipelines.
The conversion runs 100% client-side — your file never leaves your device.
