SUB and LRC are both subtitle-related formats, but they serve different purposes. SUB is commonly used for video subtitles and can store subtitle cues in several legacy formats, while LRC is a lyric format designed to display synchronized song lyrics with timestamps, often used by music players.
What is a sub file
A SUB file usually contains subtitle data for movies or videos. Depending on the subtype, it may be image-based or text-based, and it is often associated with older media players and DVD/VobSub workflows.
What is a lrc file
A LRC file stores timed lyrics in plain text. Each line typically includes a timestamp and the lyric line, making it easy for music players to highlight lyrics in sync with playback.
Can sub be converted to lrc
Yes, but only in some cases. If your SUB file contains readable subtitle text with timing information, it may be possible to convert it into LRC format. If it is image-based or uses a different subtitle structure, you may need to extract or recreate the timing manually.
How to convert sub to lrc
- Open the SUB file in a subtitle editor that can read its timing data.
- Check whether the subtitles are text-based and line-by-line.
- Export or save the content in LRC-compatible timestamp format.
- Review the timing and adjust line breaks so they match lyric-style playback.
Typical LRC lines look like this: [00:12.34]First lyric line.
Best software for conversion
Subtitle Edit is one of the best tools for subtitle conversion and timing adjustment. It supports many subtitle formats and is useful when converting subtitle timing into a lyric-style structure. For simpler cases, Aegisub can also help with editing and exporting timed lines.
If you need a dedicated converter, look for a subtitle tool that supports SUB import and LRC export. In some workflows, you may need to use File → Open, edit the timing, then File → Save As and choose LRC if available.
Things to keep in mind
- LRC is best for music lyrics, not full video subtitles.
- SUB files may not always contain directly convertible text.
- Manual cleanup is often needed to make lines readable as lyrics.
- Always verify timestamps after conversion.
Summary
SUB to LRC conversion is possible when the subtitle data is text-based and time-coded. The best results usually come from using Subtitle Edit or a similar subtitle editor, then adjusting the output to match LRC lyric formatting.
