To make YouTube Shorts from a long video, cut its strongest self-contained moments into vertical clips of up to three minutes each, then upload each clip as its own video. One podcast episode, tutorial or stream can hold enough moments for a full week of Shorts, and AI video clipping finds them without a full rewatch.
This guide covers what YouTube counts as a Short, which parts of a long video make good ones, and a step-by-step walkthrough in Picsart’s AI video clipping tool. It ends with what keeps viewers watching to the end, and how clipped Shorts can turn into paid work.
What counts as a YouTube Short
YouTube sorts a video into Shorts by its shape and its length. Nothing else about the file decides it, so any clip that fits the rules below lands in the Shorts feed.
- Aspect ratio: vertical or square. A landscape video stays a regular video.
- Length: up to three minutes. This applies to videos uploaded on or after October 15, 2024.
- Resolution: Shorts upload at a maximum of 1080p.
What to pull from a long video
A long video already did the hard part: the idea, the filming and the delivery. The job now is to find the stretches that make sense to someone who never saw the rest.
| Long video | Moments that make strong Shorts |
|---|---|
| Podcast or interview | A sharp answer, a bold opinion, a funny exchange |
| Tutorial | A single tip, a result reveal, a common mistake fixed |
| Vlog | A reaction, a reveal, a scenic beat with a caption |
| Stream or gameplay | A clutch play, a fail, a big reaction |
Finding these by hand means rewatching the whole video and noting timestamps. That hunt is the slow part, and it is exactly the part AI video clipping takes over.
The AI video clipping tool turns one long video into as many as 12 Shorts in a single run. It works with spoken videos and footage without speech, and every clip comes with captions, an opening headline and a suggested description.
How to make YouTube Shorts with AI video clipping
1. Add your long video
Upload an MP4, MOV or WebM file, or pull one from Picsart Drive. Pick a video of 10 minutes or longer, since longer sources hold more standalone moments to choose from.
2. Set the format to vertical 9:16
Choose Vertical 9:16 so every clip fits the Shorts feed. Pick the clip count, with 12 as the maximum. Leave Length on Automatic, or set a minimum and maximum so every clip stays inside Shorts range.
3. Style the captions and the opening headline
Browse caption styles under tabs like Creator, Podcast, Educational and Meme. Switch on karaoke captions so every spoken word lights up on screen. Then add an opening title and pick its look from three headline styles: AI thumbnail, AI backdrop or frozen frame.
4. Generate and compare the clips
Hit Generate clips, and check the credit cost displayed on the button before the run begins. The results grid lists each clip's length, the timestamps it came from in the original video and a score out of 100.
5. Export and upload to YouTube
Adjust the captions, timing or opening frame on the clips you want to keep, then export them as MP4 files. Upload each one through YouTube Studio or the YouTube app, using the suggested title and description as a starting point.
What makes a Short worth watching to the end
A Short competes with an endless swipe, so the craft is in removing every reason to leave. These four habits matter more than any editing trick.
Hook in the opening seconds
The first frame has to say why the viewer should stay. A bold opening headline over the first shot does that job before anyone hears a word. Use the AI thumbnail, AI backdrop or frozen frame styles to put that headline on screen from the start.
Captions for sound-off viewing
Plenty of people scroll with the sound off. Word-timed captions keep the message readable for them and hold attention for everyone else. Karaoke-style captions add movement to talking-head footage, which helps a static shot feel alive.
One idea per Short
A Short that needs the full video to make sense loses people fast. Each clip should open on a complete thought and close on its payoff. The clipping tool cuts spoken video on word-level timing, so clips start and stop on full sentences instead of mid-word.
A length that fits the moment
Three minutes is the ceiling, not the target. A sharp 25-second answer beats the same answer padded to a minute. Let the moment set the length, and leave the clip length on Automatic to let the tool judge it.
How clipped Shorts turn into paid work
Clipping long videos into Shorts is also paid work. On Picsart Earn, campaign owners post paid briefs with an approved source video, and creators clip it into short-form posts for their own channels, including YouTube. The campaign owner supplies the source, which settles the rights question before the first cut.
Start the clipping tool from an Earn campaign, and the brief’s required hashtags, @mentions and caption lines can be carried into every clip, so each submission matches what the campaign asked for. Each brief sets its own platforms, rules and reward, so browse Earn campaigns to see what is open.
