From web captions to .smi media files
WebVTT is the modern web standard, but many desktop and Korean media
players expect .smi. Converting VTT to SMI maps each
caption timecode into a SAMI <SYNC> block, so the
same subtitles play in Windows Media Player, PotPlayer, KMPlayer and
GOM Player.
The conversion runs 100% client-side — your file never leaves your device.
