SubSync

Synchronize and correct subtitle timing against audio tracks automatically

Video & AnimationFreemium

SubSync aligns subtitle files to audio tracks by matching speech patterns to subtitle text, correcting timing drift, offset errors, and framerate mismatches that cause subtitles to display out of sync. The tool handles multiple subtitle formats including SRT, ASS, VTT, and SUB and supports batch synchronization across episode series. Subtitle translators use it to sync translated subtitles to different audio tracks while streaming platforms use it to correct timing issues in user-contributed subtitle files before publication.
