How to make timed subtitles from a script
Paste the exact words from your narration or video transcript. Choose a speaking pace close to the recording, then review the caption preview. The maker groups words into readable blocks, wraps them to your chosen line width, and assigns estimated start and end times. Download an SRT file for many editing workflows or VTT for web video players.
Set pace and line width
A faster pace creates shorter display times. Choose a caption width that stays readable on phones.

Compare the timestamps with your audio. Adjusting to the real recording improves sync.
Frequently asked questions
