The AI Shorts generator that cuts Shorts from the videos you've already made

YouTube has said what decides a Short's reach: how many people choose to watch it rather than swipe away, how long they stay and how much of it they see, then likes and surveys. So a Short lives or dies in its first second and its last. Here's how Clyper's AI works toward each:

• The first line. Every Short starts on a line that makes people need the next one, and its hook score rates exactly that. Post the highest first.
• A reason to stay. It cuts whole moments, from setup to payoff, so a Short ends when the point lands and doesn't trail off. Most run 20 to 60 seconds: a Short can be up to 3 minutes, but one people watch to the end does better than a longer one they leave.
• A full screen. 9:16 at 1080 × 1920, on whoever's talking, cutting between people as a conversation moves.
• Words people can read with the sound off, placed above the title and channel name at the bottom of the Shorts player. Check a frame with the safe zone checker.

Everything YouTube has said about ranking, and how views are counted now, is in how the YouTube Shorts algorithm works.

YouTube says Shorts cut from your own long videos aren't penalized, and that since October 2026 channels that mostly re-upload other creators' videos will likely get less reach in the Shorts feed. Clyper works from your footage, so every Short is yours. Clipping someone else's? Do it only with their permission, through a clipping campaign or their own program.

A Short from your own video can also send viewers to it: add the full video as the Short's related video in YouTube Studio and it shows as a link under your handle. The steps are in how to link a YouTube Short to a video.

Up to one Short for every 2 minutes of video and 30 in all, and you choose how many. On a weekly upload schedule, a 20-minute video already fills the week with a Short a day. How often to post is in how often to post.

• Title: each Short comes with the moment's title, which you can use as a starting point. Write it for search as well as the feed: see YouTube Shorts SEO.
• Thumbnail: it shows wherever Shorts appear as tiles, like your channel's Shorts tab. Make one with the free Shorts thumbnail maker, and see how to change a Shorts thumbnail.
• The same files elsewhere: every Short is a 9:16 MP4 with no watermark, so it posts as it is on TikTok and Reels. See YouTube to TikTok and YouTube to Reels.

“AI Shorts generator” means two different tools. Some write a script from a prompt and build a Short from AI voices, stock footage or generated images. Others, like Clyper, cut Shorts from a video you already have. Clyper is the second kind: it adds no AI voices, faces or footage, so your Shorts are you, at your best moments.

If you have long videos, that's the faster route to Shorts that sound like your channel. If you'd rather not show your face at all, see making money on YouTube without showing your face. Turning a video into Shorts step by step, by hand or with Clyper, is on YouTube to Shorts.
