## Definition

Word-level sync is a captioning precision where each individual word is timed to appear or animate at the exact moment it is spoken in the audio, rather than showing full sentences at once.

## Extended Definition

Word-level synchronization is the technical foundation of modern animated captions. Traditional subtitles (SRT) display complete sentences or phrases for a duration window. Word-level sync instead times every word to the millisecond, enabling effects like individual word highlighting, sequential word appearance, karaoke-style color transitions, and bounce-per-word animations. This requires more precise speech recognition with word-level timestamps (not just sentence boundaries). The result is captions that feel dynamic and guide the viewer's reading pace, which measurably improves completion rates on short-form video. BlitzReels' transcription engine produces word-level timestamps that power all 30+ caption style animations.
