SBV (SubViewer) is a simple caption format historically offered as a download option in YouTube's caption editor, alongside SRT and VTT. Each caption block starts with a "start,end" timestamp line in H:MM:SS.mmm form, followed by the caption text, with blocks separated by a blank line.
SRT is far more widely supported than SBV — nearly every video editor (Premiere, DaVinci Resolve, Final Cut), media player (VLC, Windows Media Player), and platform accepts SRT, while SBV support is limited mostly to YouTube's own tools and a handful of older applications.
The SubViewer format uses [br] to represent a manual line break within a single caption block. This converter replaces every [br] with a space so the SRT output reads as one clean line — SRT players wrap text automatically based on player width.
