Frequently Asked Questions

What is SBV format?

SBV is YouTube's native caption format. Each caption entry has a timestamp line (start,end) followed by the caption text. YouTube's caption export tool produces SBV files.

How are end times calculated from LRC?

LRC only has start timestamps. The converter sets each cue's end time to the start of the next cue minus 100ms. The last cue gets a 3-second default duration.

How do I upload the SBV to YouTube?

In YouTube Studio, open your video, go to Subtitles, click Add Language, then Upload file, and select your SBV file. YouTube will process and display the captions.

Can I use LRC to SBV for spoken word content?

Yes. Any LRC file with timed text lines can be converted to SBV, whether the content is song lyrics, spoken word, or any other timed text.

Are my files deleted after conversion?

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

What happens to LRC metadata tags in SBV output?

LRC metadata tags (ti:, ar:, al:, by:) are not included in the SBV output. SBV only contains timed caption entries without metadata headers.

Is there a file size limit?

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

Can I convert SBV back to LRC?

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

Does the converter handle enhanced LRC with word timestamps?

Enhanced LRC word-level timestamps (angle bracket markers) are stripped. The line-level timestamp is used, and the full line text appears as a single SBV caption.

Can SBV also be used for Google Drive videos?

Yes. Google Drive's video player and Google Classroom video embedding support SBV caption files for accessibility.
