From Long to Viral: How to Turn a Long Video into Short Clips on your Phone Illustration

Short video content is now clearly dominating the way we consume online content every day. This format is also more than just a trend; it is the driving force behind online growth! TikTok, Instagram Reels, and YouTube Shorts are now the main way people discover you and your brand. But what if you primarily focus on creating long videos for your social media channels? Do you really have to start from scratch and edit them again? 

The answer is absolutely not! With the right tools, you can easily convert long videos into short clips that are perfect to post on TikTok, Reels, and Shorts. No need to turn on your PC or laptop, it is possible to repurpose your videos directly from your iOS or Android device. Thanks to AI, this process is now faster and smarter than ever before.

Why Repurpose Long Videos into Short Clips

Here are some of the reasons why this might be a great option to repurpose your long content:

  • Short attention spans. Nobody watches a 60-minute interview on YouTube! Viewers now give about 8 seconds before deciding to scroll away.
  • Reach new audiences. Building on the previous point, you can attract viewers to your full-length video by posting the most interesting parts in a short format. Moreover, algorithms favor short videos, especially on platforms like YouTube, which also offer other content formats.
  • Make the most of your existing content. One podcast episode or other video formats can be turned into over 20 viral clips.
  • Boost engagement. Captions, hooks, CTAs, and quick cuts increase viewer retention.

This is why creators, brands, and podcasters are turning to AI tools that convert long videos into short ones rather than relying on manual editing.
