Quick clarification: Klap's AI reel generator works with your existing video content — podcasts, YouTube videos, webinars, livestreams. It's not a text-to-reel tool (use Canva or Invideo for that). Klap finds the best moments in a video you already have and turns them into Instagram-ready Reels with captions, vertical reframing, and platform-optimized pacing.

How to generate Reels from any video in 3 steps
Klap scans the full video, picks the most engaging moments, crops them to 9:16 vertical with speaker tracking, and burns in word-by-word captions. You'll get 10+ Reels from a typical hour-long upload, ranked by Virality Score.
Tweak the trim, change caption styles, drop in your brand colors and logo. Download in HD or post directly to Instagram from Klap. Your next week of Reels is ready in minutes.
Every output is Instagram-ready
Klap doesn't just resize your video — it formats it for Instagram Reels. Captions positioned above the Reels UI overlay so they're never hidden. Length capped at 90 seconds when needed. Aspect ratio locked to 9:16. Cover frame auto-selected from the most thumbnail-worthy moment. Speaker tracking keeps faces centered. Drop your reel into Instagram and it looks like it was built there.
The AI knows what's worth posting
Long-form videos are 90% setup and 10% payoff. Klap finds the 10% — the one-liners, hot takes, emotional reveals, punchlines. Each Reel starts with a strong hook, builds a self-contained moment, and ends on something memorable. No more scrubbing through a two-hour podcast looking for the bit worth clipping. Each clip gets a Virality Score from 0-100.
Captions that match Reels culture
Reels viewers expect word-by-word captions with bold styling and color highlights on power words. Klap delivers exactly that — captions positioned above the Instagram UI safe-zone, color-highlighted in your brand color, and timed to the speaker. 52 languages supported. Edit the wording or restyle in seconds.

Frequently asked questions
What is an AI reel generator?
An AI reel generator automatically creates Instagram Reels from your existing content. Klap's AI reel generator works specifically with your long-form videos — it scans podcasts, YouTube videos, interviews, or webinars, finds the most engaging moments, reformats them for Instagram (9:16 vertical, 90 seconds max, captions for muted browsing), and gives you 10+ ready-to-post Reels in under a minute. It's not a text-to-video tool — you need source footage.
How do I generate Instagram Reels from a long video?
Paste a YouTube link or upload your video into Klap. The AI scans the full video, picks the strongest moments, reformats them to 9:16 vertical with captions, and returns 10+ Reels-ready clips in about 30 seconds. Each Reel is ranked by Virality Score so you know which to post first. Publish directly to Instagram or download to upload manually. See the dedicated YouTube to Instagram page for the YouTube-specific flow.
Is Klap's AI reel generator a text-to-video tool?
No. Klap doesn't generate videos from prompts or stock footage. It works with your existing video content — podcasts, YouTube uploads, webinars, livestreams, interviews. If you want to create a Reel from a written prompt or AI-generated visuals, use Canva, Invideo, or a similar text-to-video tool. If you have a long video you want to turn into Reels, Klap is the fastest way.
Can I make Reels for free?
Yes. Klap's AI reel generator is free with no credit card and no signup wall. The free plan includes 1 video free with no credit card — generate Reels at zero cost. No watermarks are added to exported Reels, ever. Try the AI clip maker for general-purpose clipping.
How many Reels can I generate from one video?
Klap typically generates 10+ Reels from a 1-hour video and 20+ from a 2-hour podcast. The exact number depends on how many strong moments the AI identifies. You can adjust the target Reel length (15-90 seconds) and count in the editor before publishing.
