How to Turn a Long YouTube Video into Shorts (2026 Guide)

You uploaded a 25-minute YouTube video. Somewhere inside it are five or six moments that would do well as Shorts — but pulling them out by hand means scrubbing the timeline, trimming each clip, re-cropping to vertical, and re-rendering one file at a time. By the time you've made three, you've lost an afternoon.

There's a faster way. This guide covers how to turn a long YouTube video into Shorts: the three methods available to you, a step-by-step workflow, the format settings that actually move the needle, and how to do the whole thing without rationing credits.

The 3 Ways to Make Shorts From a Long Video

Every method gets you a vertical clip in the end. They differ in how much time they cost you and how much of your video they actually use.

Manual editing is fine if you make one Short a month. It does not scale to a weekly posting habit. That leaves the two AI approaches — and the difference between them decides how much of your work actually reaches an audience.

Viral-moment detection optimizes for a small number of clips it thinks will pop. If your video is a loose vlog, that can be enough. But if your video has deliberate structure — a tutorial with seven steps, a talk with five points — a highlight detector will quietly leave most of it on the floor. Section-based clipping instead maps the video to its own outline and gives you a clip for every part. We go deeper on this trade-off in section-based vs viral-moment clipping.

How to Turn a Long Video into Shorts, Step by Step

Here's the section-based workflow end to end. We'll use KlydeLabs, but the shape is the same for any tool that clips by structure.

1. 1
   Upload your YouTube video

   Drop the MP4 or MOV into KlydeLabs. You don't need to download it from YouTube and re-edit it first — upload the source file once and the workflow runs from there.
2. 2
   Let it split into sections

   KlydeLabs analyzes the video and creates one clip per natural section — hook, intro, each main point, payoff. A 25-minute video typically yields 5–10 clips, so you're choosing from full coverage instead of a couple of guesses.
3. 3
   Pick the vertical 9:16 format

   Every clip is exported in 16:9, 1:1, and 9:16 from the single upload. For Shorts you want 9:16. Face tracking keeps the speaker centered so a head isn't half-cropped out of frame.
4. 4
   Decide on captions

   Captions are optional. Burn them into the clip, or skip them and use the SRT file so YouTube's own caption styling takes over. KlydeLabs reads 95+ languages from your audio.
5. 5
   Grab the titles and hooks

   Each upload comes with a creator kit — Shorts and Reels ideas, YouTube titles, and chapter timestamps — so you're not writing a hook from scratch for every clip.
6. 6
   Post across the week

   You now have more Shorts than days in the week. Schedule one a day, keep the rest in reserve, and one upload has fed your whole calendar.

How to Format Shorts So They Actually Get Watched

Getting a vertical clip is the easy part. Getting it watched comes down to a few format choices:

• Frame it 9:16, not a center crop. A naive crop chops the speaker's head off the moment they move. Face tracking follows the speaker so the framing holds for the full clip.
• Earn the first three seconds. Shorts live or die on the opening. Lead with the most interesting line of the section, not a slow "hey everyone" intro. Section-based clips help here because each one starts at a real topic, not mid-sentence.
• Treat captions as a choice, not a default. Some creators want burned-in captions for silent autoplay; others prefer platform-native captions they can restyle later. Either is valid — what matters is that you get to decide. We break down when to burn them in over in do you need burned-in captions.
• Give each Short its own title and hook. Reusing your long video's title on every clip flattens performance. Pull a distinct hook per clip from the creator kit.

How Many Shorts Can One Video Make?

More than most creators expect. The number tracks your video's structure, not its length — a tightly structured 20-minute tutorial can out-produce a rambling hour.

A single upload that yields seven Shorts is seven days of posting from one recording session. Do that once a week and you're never staring at an empty calendar again — the one-video-to-a-week workflow covers how to map them out.

Doing It Free — Without Credits or Watermarks

Most AI clip tools meter you on credits or processing minutes: a long video can drain your monthly allowance in a couple of uploads, and a re-upload of a revised file costs you again. That model turns "let me try a few more clips" into a budgeting decision.

KlydeLabs runs on an upload quota instead. You get a set number of video uploads each month, the quota refreshes monthly, and exports and downloads never count against it. No credits to ration, no per-minute meter, no surprise when one long video would have cost three credits elsewhere.

You can start without paying anything:

• Free plan: 3 video uploads a month, up to 30 minutes each, full section clips and creator kit. Clips carry a small KlydeLabs watermark.
• Starter ($9.99/mo): 10 uploads, up to 60 minutes, and the watermark comes off.

So the honest version: free gets you real Shorts to test the workflow, with a watermark; a few dollars a month removes it and raises the limits. Full breakdown on the pricing page.

The Bottom Line

Turning a long YouTube video into Shorts isn't a creative problem — it's an extraction problem. Manual editing solves it slowly. Viral-moment AI solves it partially. Section-based AI solves it completely: one upload, a clip for every part of your video, formatted vertical, captions on your terms, and enough Shorts to carry the week.

Pick one video you've already recorded. That's your test, and it might be your whole week of content.
