AI subtitle generator for video clips
FrameOS generates subtitles as part of the clipping workflow, so every short comes back captioned, editable, and burned in for social — not as a separate file you have to upload and sync yourself.
Subtitles generated automatically from speech
Drop in a video and FrameOS transcribes the speech and lays it out as timed subtitles aligned to the clip. There is no manual scrubbing to mark in and out points for each line — the subtitles arrive synced to the words, ready to review.
Word by word, not static blocks
FrameOS subtitles highlight word by word in time with the speech rather than dropping in static blocks of text. That cadence is what holds attention in the first seconds of a short, where a large share of viewers watch with the sound off and decide within seconds whether to keep watching.
Editable before you export
The common failure of auto-subtitle tools is finality: once the file is generated, fixing a misheard name means starting over. FrameOS keeps the text, font, size, position, and emphasis live-editable through review, so you correct and restyle against the real footage before anything is committed.
Burned in for cross-platform safety
Because subtitles are baked into the video at export, they play correctly everywhere with nothing extra to upload, and each platform's native caption system cannot strip or re-render them. Placement avoids overlays like the TikTok caption bar so nothing important is covered.

- Automatic, speech-aligned subtitles for every clip.
- Word-by-word highlighting for sound-off viewing.
- Editable text and styling until export.
- Burned-in output that travels across every platform.
FAQ
What is the difference between subtitles and captions in FrameOS?
In practice FrameOS treats them the same: AI-generated, timed, on-screen text burned into the clip. People search for both 'subtitle generator' and 'caption generator' for the same job of making a clip readable with the sound off.
Can I add subtitles to a video I already have?
Yes. Bring in a video by link or file and FrameOS generates subtitles as part of producing the short-form clip, which you can review and restyle before export.
Can I edit the subtitle text and style?
Yes. The text and the styling — font, size, position, emphasis — stay editable during review, so you can fix a name or change the look before the clip is rendered.
Are the subtitles burned in or a separate SRT file?
Burned in at export, so the clip plays with subtitles on every platform without uploading a separate file.
