How to turn a long video into Shorts, TikToks and Reels on iPhone.

A free workflow that turns a podcast, a stream or your own YouTube video into vertical clips ready to post, in minutes, not hours.

By Salvatore Castellitti, who builds Clipped.

Quick answer

Cut the long video into short vertical clips with a strong first line, 9:16 framing and burned-in captions. By hand in an editor, that is slow. On iPhone, Clipped does it for you on the device: open the video from Photos or Files, the AI ranks the best moments, reframes them with face tracking and adds captions. It's free, and the video never leaves your phone.

What every short needs

  1. A hook in the first seconds. A claim, a question, a surprise.
  2. 9:16 framing that keeps the speaker in shot.
  3. Burned-in captions, because many people watch muted.
  4. One complete thought. Start and end on whole sentences.

The manual way

  • Scrub the video for a moment.
  • Cut the start and end.
  • Reposition the crop as the speaker moves.
  • Add and style captions, export, post.

Fine for one clip. For 5 a day, it is a job.

Free tool: doing it by hand on a computer? The vertical video converter turns wide video into 9:16 and follows the face, and the video cropper sets a fixed crop. Both run in your browser.

The AI way: Clipped, on your iPhone

  1. Import from Photos or Files: MP4 or MOV, up to 2 hours.
  2. Choose How many clips? (1-3 up to 10+) and How long? (Auto, 15, 30, 60 or 90 seconds).
  3. Let the AI pick. It rates moments across the whole video and hears laughter, applause and big reactions.
  4. Check the viral score. Tap it to see why a clip made the cut.
  5. Polish with Captions, Look, Text, Beats, Trim, Post. Remove pauses cuts silences and filler words in one tap.
  6. Export clips at 1080p and post.

Not happy with the picks? Find different clips runs the video again and skips the moments it already chose.

Long enough to land one complete thought. Clipped lets you pick Auto, 15, 30, 60 or 90 seconds, and its clips start and end on whole sentences.
