About YouTube SBV (.sbv) files

SBV files come from YouTube’s caption editor and its legacy download option. Each cue is just a timing line such as 0:00:01.000,0:00:04.200 followed by the text, with no sequence numbers or header, which makes them small but poorly supported outside YouTube.

What converts and what doesn’t

SBV stores timing and text only, so converting to SBV drops cue identifiers. Converting from SBV is lossless.
