AI Video Captions — Timed Subtitles for Any Video
Video Captions creates timed subtitles from the speech in your video. Upload a clip, review the generated lines, choose a caption style and export a finished MP4 or subtitle file. It is useful for social videos, lessons, interviews and any content that needs to work with the sound off.
How Video Captions works
- 1
Upload an MP4, MOV, M4V or WebM video within the shown size limit.
- 2
Wait for the automatic transcript and edit any line that needs correction.
- 3
Choose a caption style, position, size and colors for the final look.
- 4
Export the captioned MP4 or download SRT and VTT subtitle files.
What you can use Video Captions for
- Short-form videos and social clips that need on-screen text.
- Course lessons, tutorials and webinars with subtitles.
- Interview clips and client videos that need a subtitle file.
Tips for better results
- Review names and numbers, since automatic speech recognition can miss them.
- Keep lines short so captions stay readable on a phone screen.
- Use a style with enough contrast against the video background.
Example
A 30-second tutorial with one speaker: generate captions, split the longest line into two, check that the first caption appears before the speech, then export SRT and review it in the editor.
What to check
- Overlapping speakers need manual review and line assignment.
- Check reading speed and line length on a phone screen.
- Download the final caption file; daily limits apply.
