How to Turn One Long Video Into a Week of Vertical Clips (Without an Editor)

Podcasts, webinars and talking-head videos are goldmines of short-form content — if you have the time to cut them up. Here’s how AI does the whole job in minutes instead.

If you make long-form video — a podcast, an interview, a course lesson, a livestream — you’re sitting on a week’s worth of TikToks, Reels and Shorts inside every episode. The problem was never a shortage of content. It was the four hours of editing per clip: finding the good moment, cropping it to vertical without cutting off the speaker’s face, cleaning up the start and end, and adding captions.

That entire workflow is now automatic. I want to show you what it actually looks like — not the marketing promise, but the real steps and real output — using Klypse, an AI video assistant built specifically for repurposing.

Step 1 — AI finds the moments worth clipping

You upload one long video (or paste a YouTube URL). The first thing the AI does is transcribe it with word-level timestamps, then scan the whole thing for the segments most likely to hook a viewer — a strong opening line, a punchy answer, a surprising claim. Instead of you scrubbing a two-hour timeline, you get a shortlist of candidate clips detected automatically.

This is the part that used to take the longest and it’s the part most people get wrong when doing it by hand — we’re bad at spotting our own best moments. Automatic highlight detection removes the guesswork.

Step 2 — Landscape becomes vertical, automatically

Here’s the step that makes or breaks a clip. Your source is 16:9 (landscape). TikTok, Reels and Shorts are 9:16 (vertical). A naive center-crop chops the speaker in half the moment they lean or move. Klypse tracks faces frame by frame and reframes the shot like a camera operator would — keeping the subject centered as they move.

No manual keyframing, no re-cropping every few seconds. The result looks hand-edited because the framing follows the person, not a fixed box. If you’ve ever tried to convert landscape to vertical video manually, you know how much time this one step saves.

Step 3 — Every clip gets a hook score

Not every detected moment is equally viral. Klypse rates the opening seconds of each clip — the “hook” — and gives it a score, with platform-specific ratings for TikTok, Reels and Shorts. So instead of publishing blind, you post the clips most likely to stop the scroll first.

This is the difference between “I made 10 clips” and “I know which 3 to post.” It turns a pile of output into a ranked publishing plan.

Step 4 — Fine-tune in the editor (only if you want to)

The clips come out ready to post — cut on natural speech boundaries, captioned inside safe zones so text never covers a face, and branded with your fonts and colors. But if you want to trim a beat or tweak a caption, there’s a built-in editor. It’s optional; most clips need nothing.

Step 5 — Publish everywhere

One source video, exported for TikTok, Instagram Reels, YouTube Shorts, LinkedIn and Facebook. The clips are vertical, captioned, on-brand, and — importantly — carry no watermark, even on the free tier.

The math that makes this worth it

The old way: one long video → maybe one or two clips, after hours of editing, if you got around to it at all. The new way: one long video → a batch of ranked, captioned, correctly-framed vertical clips in minutes. Same source material, an order of magnitude more output, and none of the tedious parts.

If you already record long-form content and you’re not consistently posting short-form, this is the gap AI closes. You can try it on your own video free — Klypse gives you 2 full-feature videos with no credit card, and there’s no watermark on any tier.
