- What actually changes when I convert SMI to VTT?
- SAMI, an XML-based format from older Windows Media Player workflows — a cue's end time is implied by the next sync point, not stated directly. WebVTT, the format the HTML5 <track> element expects natively in the browser — dot as the decimal separator, optional positioning cues. Timing and line breaks carry over as-is; anything one format can represent that the other can't is simply dropped.
