Why Auto Captions Beat Manual Subtitles
Manual Captioning
- 30+ minutes per minute of video
- Tedious timing of each word
- Typos and inconsistent formatting
- Imprecise word-level sync
Auto Captions (AI)
- Under 30 seconds for a 2-min video
- Perfect word-level timestamps
- Consistent, clean transcription
- Edit after — best of both worlds
