How to make viral clips in 3 steps
Our AI scores every second of your video against patterns from millions of viral clips. It looks for hooks, punchlines, contrarian takes, emotional peaks — the stuff that stops the scroll. Each clip gets a Virality Score from 0-100.
Vertical 9:16. Auto-captions baked in. Speaker tracking. Each clip is a self-contained viral attempt — download them all, schedule, or post directly to TikTok, Reels and Shorts.
AI that knows what goes viral
Klap doesn't just pick random moments. Every clip gets a Virality Score from 0 to 100, based on what's actually performing across TikTok, Reels, and Shorts right now. Start with the highest-scoring clips. Post the ones above 80 first — those are your best shots at the algorithm. Scored by hook strength, emotional peak, dialogue clarity, and pacing. Refreshed continuously as platform trends shift. See the AI clip generator for the general-purpose flow.
Patterns Klap's AI looks for in your video
After analyzing millions of viral clips, four patterns predict virality reliably: (1) A hook in the first 1-2 seconds that creates curiosity or surprise. (2) A contrarian take or counter-intuitive claim that triggers debate. (3) An emotional reaction — laughter, anger, surprise — captured in real time. (4) A payoff in the last 3 seconds that rewards the viewer for watching to the end. Klap's AI finds these patterns in your video and surfaces them ranked by Virality Score.
Every clip opens with a hook
On TikTok, you have 1.7 seconds to win or lose. Klap's AI finds the strongest opening line in any segment and starts the clip there — not 8 seconds in. Your viewer hears the punchline first, then the setup. That's how viral clips work. Klap can even re-order dialogue when needed (with your approval) to put the hook at second zero.
Captions designed for the algorithm
85% of viral clips are watched on mute. Klap auto-generates word-by-word captions with bold styling, color highlights on power words, and placement that survives the TikTok UI safe-zone. Edit the wording, change the style, brand the look — it takes seconds, not hours.
More shots on goal = more virals
Nobody's first clip goes viral. The creators winning on TikTok and Reels are posting 3-5 times a day, every day. Klap turns one upload into 10-15 short clips — enough to feed your calendar for a week from a single long video. Repurpose smarter, not harder. A/B test hooks and styles across clips. Schedule a week of content from one podcast episode. The bulk source flow is the long video to short video converter.

Frequently asked questions
What is a viral clip?
A viral clip is a short video — typically 15-60 seconds — that gets shared at an unusually high rate on platforms like TikTok, Instagram Reels, and YouTube Shorts. Viral clips usually share four traits: a hook in the first second that creates curiosity, a clear payoff that rewards the viewer, captions that work with sound off, and a length matched to platform sweet spots (30-60 seconds for TikTok, 60-90 for Reels).
How do I find viral clips for TikTok?
If you mean clips you've already created: use a viral clip generator like Klap to score your existing long-form videos and surface the moments most likely to perform. If you mean clips to repost: only repost content you have rights to (your own or licensed), reformat to TikTok-native styling (9:16, captions, hook at second zero), and use Klap to score multiple variants so you know which to post first. The cross-platform shortcut is the YouTube to TikTok converter.
What kinds of clips go viral?
Four patterns reliably predict virality: (1) a hook in the first 1-2 seconds that creates curiosity or surprise, (2) a contrarian take or counter-intuitive claim that triggers debate in comments, (3) an emotional reaction — laughter, anger, surprise — captured live, (4) a payoff in the last 3 seconds that rewards watching to the end. Klap's AI scans your videos for exactly these patterns and ranks every clip by Virality Score.
What's the difference between viral clips and viral shorts?
Functionally, very little — both are short vertical videos under 90 seconds optimized for algorithmic discovery on TikTok, Reels, and YouTube Shorts. "Viral clips" is the more general term (any platform); "viral shorts" usually refers specifically to YouTube Shorts. Klap generates both — every output is platform-ready for TikTok, Reels, Shorts, Snapchat Spotlight, and Facebook Reels.
How do I make viral clips from a YouTube video?
Paste your YouTube link into Klap, click Generate, and the AI returns 10-15 short clips ranked by Virality Score. The whole process takes about 60 seconds. You don't need editing skills — Klap handles the cutting, reframing, captioning and styling. You just pick which clips to post.
Does Klap's AI actually know what goes viral?
Klap is trained on millions of clips across TikTok, Reels, and Shorts, scoring hook strength, dialogue clarity, emotional peaks, and pacing. The model is refreshed continuously as platform trends shift. Clips scored above 80 are statistically much more likely to perform than randomly cut segments — but no tool can guarantee virality. Klap maximizes your odds; the content still has to be yours.
Is the viral clip generator free?
Yes. You can generate clips on the free plan to see the quality before you commit. Paid plans unlock more clips per month, longer videos, HD export, and brand customization. Most users start free, see results, then upgrade once they're posting daily.
How many viral clips can I get from one video?
On average Klap produces 10-15 short clips per hour of long-form video. A 30-minute podcast typically yields 6-8 clips; a two-hour interview can produce 20+. We pick quality over quantity — every clip is selected because it has viral potential, not just to hit a number.
