Why Should You Create Shorts From Your Existing Videos? 

Maintain posting consistency

We get it! There are days where you can’t drag yourself to film new footage. Trying to maintain posting consistency can be demanding if you are creating brand new content for every video. On those days when you can’t upload a new video, Shorts can fill the gap. They keep your channel alive and the YouTube algorithm happy because it sees regular activity. 

Get more views, faster 

Many YouTube creators (especially novice creators) have reported that it is a lot easier to drive views for YouTube Shorts. Posting Shorts can be a great way to boost visibility and reach a wider audience. Even better, you can position Shorts as teasers for your long form video. By linking to your full-length videos in your Shorts, you can intrigue viewers and direct them to the main video.

A testing ground 

Unsure about a new video idea? Try it out in short form! Shorts offer a low-commitment way to test the waters and gauge audience reaction. If you see your ideas take off in Shorts, you can then dedicate more time to shoot a longer form video in great depth. 

And it’s easy to create! 

Let’s be real: creating a full-length video can be taxing. With Shorts, you have a simpler, quicker medium to work with. It can be a breeze to edit and upload, especially when you’re repurposing content from your existing videos. With the right tool, it’ll only take you a few minutes to create multiple Shorts from your existing long form videos. 

How to Create Shorts From Your Existing Videos (Step-by-Step Guide)

Now that you are ready to turn your existing videos into YouTube Shorts, let’s look at how you can do this step-by-step with the YouTube App. 

Step 1: Go to Your Library

First, open up the YouTube app on your mobile and navigate to the Library tab. Note that you can only edit a video on your on channel into Shorts so make sure you’re logged in. Choose any long form video longer than 2 minutes to see the Edit into Short option. 

Step 2: Start creating Shorts 

When you tap on the video you’ve chosen, there’s a handy little button labeled “Remix” right beneath the video title and choose ‘Edit into a Short’.

Step 3: Trim 

Now, you’ll be on the Shorts creation page where you can select a portion of your long-form video to turn into a Short. To adjust the duration, you can use the slider at the bottom of the screen to change the start and end of your clip. As you do so, keep an eye out for the red bar on top of your screen. That’s your 60s timer to make sure that your clips do not go over 60 seconds. 

Once you select your clip, if it’s under 60 seconds, you’ll have the option to add in additional media or clips to this short. Tap on your media library icon at the bottom-left and select any video you’d like to merge.

Step 4: Edit it your way 

You can then edit your Shorts similar to how you edit any YouTube Shorts. We wrote an entire guide on editing tips for YouTube Shorts for you to learn all the ins and outs of creating YouTube Shorts! 

Step 5: Get it ready for publishing 

Once you’ve prettied up your Short, tap ‘Next’. Type in a catchy title that grabs attention. Make sure you stay within 100 characters to meet YouTube’s platform requirement. Once you are done, tap the ‘Upload Short’ button to publish. Voila! Your Short is out for the world to see. 

Your published YouTube Shorts will also include a link back to your original YouTube video. Viewers can navigate back to your original long form video. You can convert these views into loyal viewers.

Top Tips for Creating Shorts from Your Existing Videos:

With YouTube Shorts, creators have a fresh way to engage their audience. These short videos can be highly impactful when done right.

Pick your best moment

Keep in mind that your YouTube Shorts audience may differ from your full-length video viewers. Given the short duration (less than 60 seconds), maximize every moment and skip lengthy intros. Identify standout moments, whether they’re funny segments, vital tips, or heartfelt messages. Shorts are designed to grab attention quickly, so choose content that resonates.

Link back to your long form video (when possible)

Creating shorts from YouTube videos also lets you promote your longer content. Use the short as a teaser to guide viewers to the complete video.

Consistency matters

Consistency is key on YouTube, including with shorts from your video content. Regularly producing shorts keeps your audience engaged and coming back for more, especially if you’re just starting out. Posting consistently provides more data to learn from, enabling continuous content improvement.

Optimize every second

Consider the algorithm game—YouTube wants viewers to stay engaged. Average view time matters. Plan your content accordingly, making every second count so viewers don’t drop off and impact your average view time.
