SBV is the simple caption format YouTube used for a long time (and still exports from some places). Most editors, players and other platforms expect SRT, so here is how to convert.
SBV vs SRT
SBV: 0:00:01.000,0:00:03.500 Hello and welcome back. SRT: 1 00:00:01,000 --> 00:00:03,500 Hello and welcome back.
The text is the same. SRT adds a number for each subtitle, uses an arrow between times, a comma before the milliseconds and two-digit hours.
