YouTube Shorts Generator — Repurpose Long Videos Free

Paste your YouTube video URL or long-form script into the free YouTube Shorts Generator above. The AI identifies the peak-engagement moments — surprising facts, emotional peaks, or high-value tips — and rewrites each one into a standalone 60-second short form video script complete with a hook, body, caption suggestions, and CTA. Creating youtube shorts this way lets you extract 5–10 Shorts from a single long video without filming new content or manually scrubbing through footage.

A high-performing Short script opens with a hook in the first 2–3 seconds that creates immediate curiosity or delivers a clear promise. The three highest-converting hook formats for short form video are: the contrarian hook ("Stop doing X — here's why"), the result-first hook ("I grew to 10K in 30 days — here's how"), and the question hook ("Why do most creators fail before 1,000 subscribers?"). Shorts with a strong hook see 3–5× higher watch completion, which is the primary signal the algorithm uses to push your video to new viewers.

YouTube Shorts must be 60 seconds or under to qualify for the Shorts feed and Shorts monetization. For maximum algorithmic reach when creating youtube shorts, the optimal length is 30–55 seconds — long enough to deliver a complete idea, short enough to maximize rewatch rate. Shorts under 45 seconds consistently achieve the highest watch completion rates, which tells the algorithm your short form video content is worth distributing to viewers who haven't discovered your channel yet.

Yes — viral shorts can dramatically grow your subscriber count, but the most effective strategy pairs them with long-form content. Create a Short that delivers one strong insight from your long video and drives curious viewers to watch the full version. Subscribers who find you this way are pre-qualified for long-form content — they watch longer and engage more. Channels that combine viral shorts with strong long-form videos grow faster than those using short-form content alone.

To create a youtube short from scratch, you need three things: a strong hook (first 2–3 seconds), a tight 45–60 second script with one clear idea, and a call to action at the end. The easiest way to learn how to create youtube shorts is to start with content you already have — paste a long video URL into CheckTheWorth's free generator and it writes the full script for you. If you're starting with a blank slate, pick one counterintuitive fact, surprising result, or common mistake in your niche and write 6–8 sentences around it. When learning how to create a short on youtube, vertical 9:16 framing and bold on-screen text are the two biggest factors in watch completion after the hook.
