or drop .srt file
Upload video, get a transcript via Whisper AI, edit if needed, burn subtitles directly into the video file. Style controls for font, size, position, background. Outputs hardcoded MP4 that works everywhere.
Why this exists
Mobile users default to muted playback. Videos without burned-in captions lose 60-80% of attention in first 2 seconds. Facebook auto-captions are unreliable and viewers don't enable them.
Use cases
- Add captions to UGC creator videos before launching
- Make videos accessible without depending on Meta auto-captions
- Translate captions for international campaigns
- Add brand-styled captions consistent with creative direction
