How Shorts caption generation works
Generate captions
Create a timed draft for the selected clip and review the text before styling.
Export for YouTube
Download a captioned video or keep SRT, VTT, or text for upload, archive, or team review.
Shorts captions should match the final clip.
A Short usually works because one moment is clear. Captioning the whole source video can create extra cleanup if only one vertical clip will be published.
Use AutoCaption after the Short is selected or trimmed. Review the caption timing, remove lines that no longer belong, and check names, numbers, and mixed-language phrases before export.
What to check before publishing
Clip boundaries
Make sure the caption track starts and ends with the final Short, not unused source footage.
Timing
Check that captions appear with the spoken line and disappear before the next idea starts.
Searchable wording
Keep names, product terms, and topic words accurate so the caption file is useful beyond the first upload.
Vertical layout
Preview the caption style in the final Shorts frame before exporting.
Export for YouTube and reuse
Captioned video
Use this when you want the visible caption style to stay inside the Short.
SRT or VTT
Use these when YouTube, a website, archive, or teammate needs a separate timed-text file.
YouTube Shorts caption questions
Can AutoCaption generate captions for YouTube Shorts?
Yes. Upload the Short or selected source clip, generate editable timed captions, review the track, and export the available file or captioned video format.
Should I caption the whole YouTube video or only the Short?
Caption the final Short when that is the only clip being posted. Caption the full video when you also need subtitles for the long-form upload, archive, or translation workflow.
Can I export Shorts captions as SRT or VTT?
Yes. AutoCaption supports SRT and VTT export workflows after you generate and review the caption track.
Can I edit Shorts captions before export?
Yes. You can edit text, timing, line breaks, and style before downloading the final output.
What should I check before publishing a captioned Short?
Review the hook, names, numbers, local phrases, timing, line breaks, and whether the captions fit the final vertical frame.
