How to convert long video to short video in 3 steps
The AI scans your full video for hooks, punchlines, emotional peaks, and quotable lines. In about 30 seconds, you get 10+ ready-to-post short clips ranked by Virality Score. Each clip is auto-reframed to 9:16 with captions baked in and speaker tracking keeping faces centered.
Export individual clips or batch-export the whole set. Connect your YouTube, Instagram, and TikTok accounts to publish straight from Klap, or schedule weeks of content with the built-in calendar.
10+ viral shorts in 30 seconds — no editing needed
Stop wasting hours scrubbing a timeline. Klap's long video to short video converter analyzes your entire upload in about 30 seconds and returns 10+ short clips you can post immediately. Each one is sized for vertical platforms, captioned, and ready to share. Upload a single long video, walk away, and come back to a week of content.
Every clip gets a Virality Score from 0-100
Klap doesn't just cut your video into chunks — it scores every clip on hook strength, pacing, retention signals, and topic relevance. The most viral-ready shorts are surfaced first, so you always know which clip to post next. Stop guessing what will hit. Test more, post smarter, and double down on what works.
Direct your AI with plain-English prompts
Tell Klap exactly what you want from your long video. Type prompts like "find the funniest moments", "extract all product mentions", or "get every Q&A answer" — the AI understands natural language and pulls exactly the moments you ask for. Perfect when you have a specific story to tell or a specific clip your audience expects.
Convert long videos in 52 languages
Klap's AI works in English, Spanish, French, German, Portuguese, Italian, Dutch, Polish, Indonesian, Mandarin, and 20+ more languages. Captions are auto-generated in your video's source language with 98% accuracy. You can also translate clips between languages in one click — convert a Spanish podcast into an English short, or a Mandarin interview into a French Reel.
Auto-captions and AI Reframe 2 built in
Every short comes with captions perfectly synced to speech and animated keyword highlights that boost watch time. AI Reframe 2 (Klap's content-aware reframer) detects content zones — webcam overlay, gameplay backdrop, screen recordings — and focuses on the active speaker face or saliency point as it reframes from 16:9 to 9:16. No awkward cropping, no missed faces. Multi-layout support handles split-screen interviews, picture-in-picture gameplay, and 3- and 4-screen podcast layouts automatically.
Convert YouTube video to shorts in one paste
Drop any YouTube link into the converter — public videos, your own uploads, long-form interviews, podcasts, livestreams. Klap pulls the video directly, processes it, and delivers your shorts without any download or transfer step. The same flow works for Vimeo, Twitch, Google Drive, Dailymotion, and Facebook URLs. Dedicated flow: YouTube to Shorts converter.
Built for every kind of creator
Klap's long video to short video converter works the same way for everyone — but the wins look different depending on what you make. Pick the persona closest to you to see the output you can expect.

Posting daily used to mean editing daily. Now one long YouTube video becomes 10+ Shorts that drive subscribers back to your main channel. Creators who post 5 Shorts per week from repurposed long-form content see channel growth at 3-5x the rate of long-form-only creators. Some Klap users have grown from 1K to 100K subscribers in weeks doing exactly this.

The converter pulls the video directly from YouTube, scans the full content, and returns 10+ Shorts-ready clips in about 30 seconds. Clips are pre-sized to 9:16 vertical with captions and ready to upload to YouTube Shorts, TikTok, or Reels.
How does Klap's video to shorts converter work?
Klap's AI analyzes the audio, visuals, and pacing of your long video to find the moments most likely to perform well as shorts — hooks, emotional peaks, punchlines, and quotable lines. It then extracts those moments, applies speaker tracking and 9:16 reframing, adds animated captions, and assigns each clip a Virality Score before returning them to you.
What video formats and sources does Klap support?
Klap accepts MP4, MOV, AVI, MKV, WMV, and FLV file uploads up to 4 hours long. You can also paste URLs from YouTube, Vimeo, Twitch, Google Drive, Facebook, Dailymotion, Zoom, Loom, and Riverside. No software download required — the converter runs entirely in your browser.
How long can my source video be?
Klap handles videos up to 4 hours long in a single upload. The converter is built for podcast episodes, full livestreams, webinars, and long YouTube videos — not just short interviews. Credits scale with video length, but processing time stays around 30 seconds to a few minutes regardless of source length.
Does Klap add watermarks to my shorts?
No. Klap never adds watermarks, even on the free plan. Your clips are clean and 100% yours — post them on TikTok, Instagram, YouTube Shorts, or anywhere else without any Klap branding in the corner. Unlike most free converters, we don't gate watermark removal behind a paywall.
How many shorts can I create from one long video?
Typically 10+ shorts from a 30-minute video, 20+ from a 2-hour podcast, and 30-50 from a 4-hour livestream. The exact number depends on how many strong moments the AI identifies — videos with lots of distinct talking points or action peaks generate more clips. You can also adjust the target number and clip length before exporting.
