Your .smi file won't open in modern players?
Legacy .smi (SAMI) files from old Windows Media content
or Korean movie releases often won't open in modern video players.
Converting SMI to SRT reads each <SYNC Start="ms"> block and produces a plain
SubRip subtitle — the most widely supported format around — so your
captions work in every player and editor.
The conversion runs 100% client-side — your file never leaves your device.
