Want to know the secret to gaining double the views of your content? Simply repurpose your Youtube videos for Instagram! Here is everything you need to know.

Why This Method Works So Well Against Marketing Norms

You put a lot of time into creating your YouTube videos, and they contain a ton of good stuff that most will never see. Meanwhile, Instagram has over 2 billion monthly users that scroll for hours at a time daily.

Think about this. You just put in the time to film that YouTube Video. Why not use that one video and create 10 Instagram Reels? Instagram users alone now spend over 60% of the time on the app just watching video, so that is a perfect medium for your content.

Research says 76% of marketers believe Instagram has the best video ROI and engagement. That is significant. If you are not on that platform you are basically leaving free money on the table.

The Influencer Marketing Industry is a $32.55 billion industry this year. Additionally, 72.8% (nearly 73%) of Instagram users are aged between 18 and 34 years old. These are your people who want to look at your content.

Understanding Differences Between a Platform

YouTube and Instagram are very different platforms. YouTube watchers prefer longer, packed, informational content, while Instagram users want quick tidbits they can see in seconds while waiting in line.

For instance, your 10-minute YouTube tutorial can be archived into five, 60-second Instagram Reels. Each focuses on a different pain point and bring in new followers to your brand.

Instagram Reels are reaching over 726.8 million users and capturing 35% of screen time, yet only 20.7% of creators are posting, this is a chance for a creator to become a creator!

Instagram differs in the following way:

• Vertical Format: Videos will need to be in 9:16 ratio for Reels and Stories
• Shorter Attention Spans: You only have 3 seconds to capture their attention
• Silent Viewers: Most viewers will watch without the audio being played and therefore the use of captions should be used
• Discovery Algorithm: Reels can get up to 67% of views from non-followers

Step 1: Save Your YouTube Video to Your Device in the Best Way Possible.

Never download your videos through a third-party downloader. Always download your videos directly from YouTube Studio. You are getting access to the original, quality uncompressed video file.

Go to YouTube Studio, locate your video, and click the download button. You will receive the best quality possible now. You really want that because Instagram will compress your videos again once it uploads.

Uploading a high-quality video means you will have an overall professional finish. Blurry videos get scrolled through immediately. High-quality videos stop the scroll.

Step 2: Choose Your Best Content Moments

Not everything in your YouTube video is meant for Instagram. You will have to dig a little to find the gold nuggets. These are moments in your video that are quick to create value or create an emotional response.

Ask yourself questions like these.

• Of the content you reviewed, what is the best value in the first 60 seconds?
• What made you laugh, or caused you to say "wow," while you filmed?
• What tip could stand alone without any context?
• What is the most controversial or the biggest surprise?

Videos that are over 26 seconds get the most engagement, but Instagram Reels have a maximum time of 90 seconds. Find those moments that have value while keeping the average audience's attention.

Step 3: Format for Mobile Displays

Most creators fail in this step. They crop their horizontal video and then wonder why it doesn't work. It needs to be reformatted for vertical viewing.

The editing apps have built-in Instagram presets that expedite the design process. Apps like CapCut, InShot, or Adobe Premiere Rush can help by allowing you to resize, crop, and reframe specifically for Reels with just a few taps.

Your horizontal 16:9 YouTube video is going to become vertical 9:16 for Reels. Don't simply add black boxes to your horizontal video. Zoom, reposition, and make it appear intentional.

Step 4: Add Captions That Convert

It’s a shocking statistic that more than 80% of social media videos are watched without the volume on. If you are not using captions, then you are essentially invisible to most viewers.

Burned-in captions are basically subtitles that accompany, and are burned into, your video. They guarantee that whether the volume is turned on or off, your message will land with the viewer. Most editing apps have built-in, auto-generate captions nowadays, or you could create and edit your own text overlays.

Make your captions easy to read:

• Choose fonts that are large and bold.
• Use high-contrast colors. (For example, white text on a dark background.)
• Keep their location at the bottom third of the screen.
• Break up longer sentences into smaller, more digestible pieces.

Captions are beneficial beyond adding accessibility for your viewers. Captions help with Search Engine Optimization (SEO). With Instagram, the platform can read your captions and follow up with suggested content to those that engage with your post.

The Three Types of Video Instagram Supports

Instagram allows you to post to three different sections of videos on the platform. Each section is meant to help serve a different purpose, and fully understanding the difference can help you broaden your reach.

Instagram Reels. Reels are what you will want to utilize to drive growth for your account. They are viewed 140 billion times a day between Instagram and Facebook. Reels can be found in the Reels tab, and on the Explore page by people that do not follow you yet.

Reels are typically good for sharing educational tips, entertaining moments, or anything trendy. The best length for a Reel is under 90 seconds.

Instagram Stories can develop a deeper relationship with your current followers. But remember, Stories are only available for 24 hours, unless you save them to Highlights. That said, 70% of Instagram users will spend time utilizing the Stories feature each day.

You can post Stories that share behind-the-scenes content, short updates to a project, or even interactive polls or questions. If you want to drive traffic back to your long-form YouTube video, use some link stickers in your Stories so people can click through.

Instagram Feed Videos (one-minute videos) live forever in your profile grid. Your feed videos can be up to 60 minutes long, but typically shorter videos will perform better on the platform. The engagement rate for a video post is 49% better than that of a static image.

Feed videos will be the best place to share content that you spent a lot of time curating and want to keep long-term. Feed videos are good for sharing testimonials, product demonstrations, or tutorials that are considered evergreen content.

Creating Hooks That Stop the Scroll

The first three seconds determine everything. Users scroll fast. Your opening must grab attention immediately or you've lost them forever.

Start with a bold question: "Want to double your sales in 30 days?" Lead with a shocking stat: "93% of people are doing this wrong." Show something visually stunning right away.

Videos under 20 seconds have a 15% higher completion rate than longer Reels. But that doesn't mean all your content should be ultra-short. It means your hook needs to work harder.

Making Hooks that Stop the Scroll

The first three seconds can actually tell you everything. Users scroll quickly. Your hook has to grab their attention instantly or they are gone for good.

You can start with a bold question: "Do you want to double your sales in 30 days?" You could launch with a crazy stat: "93% of people are doing this wrong." You can show something truly jaw-dropping as soon as the video starts.

On that note, videos that are 20 seconds or shorter get completed 15% of the time than longer Reels. But even though your content doesn't have to be that short, your hook has to work harder!

Frequent Mistakes that Wreck Your Reach

Do not use anything that is not your own content. Copyright strikes can ruin your account. Only repurpose a video that you make or have permission to use.

Do not use your YouTube thumbnail as the cover for your Reel: It is simply lazy and clumsy. Design and create your own cover that fits Instagram's vertical size on a cover photo.

Although it may be easy to overlook, make sure to turn on high-quality uploads within the app.settings. In settings, find Data Usage, Media Quality, and toggle on the button for "High quality uploads." You'll see a huge difference in quality with your videos!

Don't simply copy your caption from YouTube onto Instagram; each platform has its own unique culture and language. You should re-develop your message so that it fits the platform.

Converting Viewers To YouTube Subscribers

Your Instagram content should be a teaser for your YouTube channel! Every Reel is an ad for the full video. Don't just post and pray!

Make sure you have clear calls to action in your captions. "This is just the beginning! Click the link in my bio to watch the full 10 minute tutorial on my Youtube channel I'm teaching you the entire system."

Use Instagram's link sticker in your stories to drive direct traffic. Make sure you add your YouTube link in your bio and mention it regularly.

Starting January 2025, you'll be able to upload Reels to Instagram for up to 3 minutes in length. This will give you added space to add tons of value, while still keeping content snackable.

The Use of AI in Video Repurposing

Going from a horizontal video to a vertical video could take hours. Not anymore. AI tools can now do all the heavy-lifting in a matter of minutes.

Modern AI video generators can automatically detect the best moments in your YouTube videos. They will find hook points, add captions, resize for vertical video formats, and export ready to post content.

This technology is a game changer for content creators. What used to take an entire editing team can now be done by one person with the right tools.

Moving Forward to Success on Instagram

Now, here is your next plan of action. Download a recent high-performing YouTube video today. Use a video editing app to extract three clips from different sections of the video, and make them into verticals of 30-60 seconds each.

Now add captions to each clip, and create attention-grabbing covers. Write the captions so they include very clear call-to-action directions. Schedule the posts to go during multiple opportune times over the course of the next any week.

And since you’re nice and organized; at the end of the week, check to see which clips performed the best for you. Double down on that specific type of content, and test out different hooks, and formats with other topics. Let the data inform your future content strategy.

Keep in mind: reels get 1.36× more reach than carousels, and an even greater reach than static posts. When you create a crocheted YouTube video, it’s really 10+ Instagram reels waiting to become an Instagram post.

The creators who are winning on Instagram in 2025 are not doing it from scratch every time they want to post. They are smart about what content they put out across platforms and into their macro content pillars. One filming sesh, can go to multiple platforms, and maximum impact.
