Frequently Asked Questions

What is LRC format?

LRC is a plain text format for syncing lyrics to audio. Each line begins with a bracketed timestamp like [01:23.45] followed by the lyric text. It is supported by most desktop and mobile music players.

How are end times handled in LRC since SBV has them?

LRC only uses start timestamps. The SBV end time is discarded during conversion. The LRC player determines when a lyric line ends by reading the next line's start timestamp.

How do I download SBV from YouTube?

In YouTube Studio, go to Subtitles for your video, click the three-dot menu on a caption track, and select Download. YouTube exports in SBV format.

How do I use the LRC file in foobar2000?

Place the .lrc file in the same folder as the audio file and give it the same base name (e.g., song.mp3 and song.lrc). foobar2000 with the Lyric Show Panel component will load and display the synced lyrics.

Are my files deleted after conversion?

Yes. Files are uploaded over HTTPS and automatically deleted from the server after the LRC is ready for download.

What timestamp format does the LRC output use?

LRC uses [MM:SS.xx] centisecond format. SBV's millisecond timestamps are rounded to centiseconds during conversion.

Is there a file size limit?

SBV files are very compact plain text. The 50 MB server limit is not a concern for any SBV caption file.

Can I convert LRC back to SBV?

Yes. ChangeThisFile supports LRC to SBV conversion for round-tripping between formats.

Can I use the LRC file in iPhone music apps?

Several iOS music player apps support LRC, including Cs Music Player, Marvis Pro, and Soor. Standard Apple Music does not support external LRC files.

Does the converter handle multi-line SBV captions?

Multi-line SBV captions are joined with a space in the LRC output. Each SBV cue becomes one LRC line regardless of how many lines the original caption had.
