If you’re posting long-form videos on YouTube, you already have the raw content for short-form success. YouTube Shorts, TikTok, and Instagram Reels are some of the fastest-growing platforms for discovery—and short, engaging clips are the format that gets people to stop scrolling.

But editing down a long video into viral short clips takes time, creativity, and effort… unless you’re using AI.

With AI Studios' Video Highlights feature, you can automatically pull out the best moments from your long YouTube videos and transform them into vertical, high-impact Shorts. No manual editing. No guesswork. Just quick, smart repurposing that brings new life to your existing content.

Why You Should Be Turning Long YouTube Videos into Shorts

Repurposing long videos into Shorts helps you:

  • Reach wider audiences with bite-sized content
  • Highlight your most valuable, funny, or emotional moments
  • Promote your full-length videos through teaser clips
  • Increase engagement across YouTube, TikTok, Reels, and more
  • Save time while expanding your content output

And now with AI, you don’t need to hire an editor or spend hours manually cutting your footage.

AI Studios Also Offers a Free YouTube Video Downloader

To make things even easier, AI Studios provides one of the best free YouTube downloader tools. You can paste the link to your published YouTube video, and it will automatically download in high quality—ready to use inside the AI Studios editor.

No third-party apps or browser extensions needed. Just paste, download, and start creating.

How to Use AI to Create Shorts from Long YouTube Videos

Step 1: Download or Upload Your Video

Paste your YouTube video link into AI Studios using the free downloader, or upload the video file directly if you already have it saved. The platform supports common formats like MP4 and MOV.

Step 2: Open the Video Highlights Tool

Head to the Video Highlights section in your AI Studios dashboard. This tool uses AI to scan your long-form video and automatically detect the best, most engaging moments—no need to manually scrub through footage.

Step 3: Let the AI Generate Clips

The platform identifies top-performing moments based on tone, energy shifts, pacing, and keywords. It then creates a set of short clips (usually 15 to 60 seconds long) that are trimmed and ready for review.

Step 4: Customize and Export for Shorts

Preview your clips and make quick edits if needed. Then export in the 9:16 vertical format, perfect for YouTube Shorts, TikTok, and Reels.

Step 5: Post and Watch It Grow

Upload your Shorts directly to YouTube or schedule them throughout the week to build momentum. You can even include captions, trending sounds, or CTAs to boost engagement.

Bonus: Translate, Caption, and Personalize Your Shorts with AI

AI Studios doesn’t stop at clipping. Once your video is trimmed into Shorts, you can enhance and localize it with powerful AI features that help you reach wider audiences and maintain a polished, professional look.
