How to Turn a YouTube Video into Facebook Reels with AI Video Cut

You’ve spent hours editing a YouTube video; researched, recorded, cut, and polished it. Once it's published, it might feel like the job’s done. And while today’s online ecosystem is video-first, that same piece of content has the potential to do more than sit on a single platform. One of the easiest ways to extend your reach is to convert YouTube videos into short, vertical clips for Facebook Reels.

More than ever, creators, coaches, small business owners, and marketers are looking for quick wins with the content they already have. Here's how to make this fast and clean transition without starting from scratch.

Why Even Bother Reusing YouTube Videos as Facebook Reels?

Short-form video is everywhere now, and not without a reason. It’s been already proved many times that platforms are prioritizing it in feeds, and Facebook is surely no exception. Facebook Reels now have prominent placement in the app and are favored by the algorithm but, unfortunately, many creators sit on long-form videos that only ever see the light of day on YouTube. So turning those videos into short clips doesn’t just give them a second life; it helps them reach a different audience altogether. 

And considering that Facebook Reels are often discovered by people who don’t follow your page, it means you’ve got more chances to get new eyeballs on your content without creating something entirely new.

What Makes a Facebook Reel Work?

If you think that repurposing a YouTube video as a Facebook Reel is simply chopping it down, it’s not exactly true. Facebook Reels thrive on immediacy, so the first few seconds of your short clip matter more than ever! If a viewer stops scrolling, the video doesn’t get seen, period. 

There’s no secret ingredient that makes your Reel go viral, neither is there one-fits-all approach, so it’s wise to at least get the most of the format, such as:

• Stick to under 90 seconds
• Keep it vertical (9:16)
• Make the first 3 seconds count
• Use captions as over 85% of people watch Facebook Reels without sound
• Don’t over-edit; polish, but don’t sterilize

Come up with one clear moment or message from your video that can stand on its own. A powerful quote, a concise tip, a joke, a reaction - all these are the pieces that tend to travel.

From YouTube to Facebook Reels: How to Turn One into Another

What if we tell you that you don’t need to download editing software or wrestle with frame sizes to make this work? Tools like AI Video Cut do most of the work for you.

Step 1: Copy and paste your video’s YouTube URL into the tool.

So that AI Video Cut could pull the video directly without needing to upload a file.

Step 2: Let AI detect highlights (or pick your own).

AI Video Cut scans for high-engagement moments like jokes, potential viral moments, and other stuff depending on the prompt you choose. Say, you’re choosing an Instructions prompt. In this case, our tool will detect steps with actual instructions and compile a short video that contains only them. 

Step 3: Choose the 9:16 aspect ratio.

Our service automatically adjusts framing and scales the video to fit the 9:16 ratio. But you can change the crop if needed to keep the focus where it belongs.

Step 4: Add subtitles and export.

As we’ve already mentioned, most viewers don’t watch Reels with sound on, at least on Facebook. This is why adding auto-generated captions would make your video more accessible and easier to follow. Once you're done, export the final clip.

Step 5: Upload to Facebook.

You can post your new clip directly from your phone or via Meta’s Creator Studio. Don’t forget to include a caption with a hook or a question. Anyway, something that invites engagement.

Tips & Best Practices for Better Reach

Not every video will take off immediately; sometimes, it might take quite a lot of time. Nonetheless, there are a few small improvements that can help your Reels get noticed: 

• Use music from Facebook’s built-in audio library
• Post when your audience is most active (you can figure that out in the in-app analytics tool). 
• Add a few hashtags (but not a wall of them!)
• Keep testing different types of clips from your content library

And remember: not every Reel will make you go viral; you’re doing this to be visible. 

What Kinds of YouTube Videos Work Better as Facebook Reels?

As not everything that glitters is gold, not every YouTube video has just the right potential to shine on Facebook. Audiences and algorithms are different on these platforms, so needless to say that certain video formats lend themselves naturally to being clipped into Reels. 

Which ones? Educational content, in particular, tends to travel well: tips, how-tos, listicles, and “did you know” moments are all easy to isolate and repackage. Interviews also may work quite well, just as vlogs that can yield funny or heartfelt moments and even webinars or livestreams that can be mined for a concise insight or call to action.

YouTube Content Repurposing Means One Video, Many Uses!

The indisputable power of content repurposing is that it doesn’t have to be a one-and-done affair. The right tools and a bit of intention do wonders, and your YouTube videos can keep working long after they’ve gone live. Facebook Reels offer a low-effort yet high-reward opportunity to do just that.

AI Video Cut takes the heavy lifting out of the process, so you can spend less time editing and more time creating.

Try it yourself: Pick a video from your channel, run it through AI Video Cut, and post your first Reel. One piece of content, multiple platforms, and more people reached!
