alass is a Rust command line tool that automatically synchronizes subtitles to movies or reference subtitles. It corrects constant offsets, splits from ad breaks or director's cuts, and different framerates using a fast, language-agnostic alignment algorithm.
Use cases
- fix subtitles that are out of sync with a movie
- correct subtitle timing after ad breaks or director's cut splits
- resync subtitles with a different framerate
- align a subtitle file to a reference subtitle instead of the video
- batch-fix incorrectly timed downloaded subtitles
When to choose
- you need automatic, accurate subtitle synchronization without manual offset tweaking
- you want language-agnostic alignment between video audio and subtitle text
- you need to fix splits and framerate mismatches, not just constant offsets
When to avoid
- you need a GUI subtitle editor for manual adjustments
- you need subtitle formats other than srt, ssa/ass, or idx
- you need an actively developed tool with frequent updates
