From long video to a captioned Short

Clip Vuno's AI Shorts Maker combines local English speech recognition with a review-and-export workflow. It is a beta, and your judgment remains part of the edit.

1. Choose a clear recording

Use an MP4, MOV or WebM with understandable English speech. The file must be under 150 MB. Analysis covers the first 15 minutes, even when the source is longer. A desktop browser is recommended for the media engine and model downloads.

2. Review the suggested moments

Whisper generates a transcript with segment timings on your device. The tool uses those timings and simple text signals to suggest up to five non-overlapping moments. It does not use a language model to judge virality or understand the full story. Some recordings may produce fewer suggestions.

3. Make the hook your own

The initial hook is an excerpt from the transcript, not a newly written AI headline. Rewrite it so the clip makes sense by itself. Check that it matches what the speaker actually says, and review the start and end of the cut.

4. Frame the subject

Use the static crop-position slider and framing preview to choose what remains visible in the vertical frame. This beta does not track a moving speaker or switch between speakers automatically. Preview the source moment to catch movement that leaves the crop.

5. Check captions and export

Choose Highlight, Box or One word styling. Caption animation divides each recognized segment into approximate phrase or word timings; it is not precise word alignment. Keep one caption line per timed segment when editing the text.

The output is a 720 × 1280 H.264 MP4 with AAC audio, a hook, animated captions and a small Clip Vuno tag. Review the actual exported video before posting it. The free beta allows one successful export per browser per day, resetting at 00:00 UTC. This trial allowance uses browser storage rather than an account.

What is planned

Semantic moment selection, generated hooks, automatic speaker tracking, two-hour processing and multiple tag-free exports are planned. They are not activated by Dodo test checkout.
