How to Change a Video to a Short on YouTube

YouTube Shorts are one of the easiest ways to repurpose long videos into short, vertical clips that can reach more viewers. If you already have a long video, podcast, tutorial, interview, vlog, webinar, or product demo, you do not always need to create new content from zero. You can change a video into a YouTube Short by trimming the best moment, formatting it vertically, adding captions, and uploading it as short-form content.

In this guide, you will learn how to change a video to a Short on YouTube and how tools like LongToShorts.com can help you turn long videos into short clips faster with AI.

What Is a YouTube Short?

A YouTube Short is a short-form video made for quick viewing on mobile devices. Shorts are usually vertical, easy to watch, and designed to capture attention in the first few seconds. They are perfect for highlights, quick tips, funny moments, reactions, tutorials, and short educational content.

If your video is long, the goal is not to upload the entire video as a Short. The goal is to find the best part of the video and turn it into a short, clear, and engaging clip.

Can You Change a Normal YouTube Video Into a Short?

Yes, you can turn a normal video into a YouTube Short. There are two main ways to do it. You can use YouTube’s built-in tools from the mobile app, or you can use an AI tool to create short clips from a long video before uploading them to YouTube.

The best method depends on your content. If you only need one quick clip, YouTube’s built-in editor can be enough. If you want to create multiple Shorts from one long video, an AI video clipping tool can save a lot of time.

Method 1: Use YouTube’s “Edit Into a Short” Feature

YouTube allows creators to create Shorts from some existing videos directly inside the YouTube mobile app. To do this, open your video in the YouTube app, tap the remix or edit option if available, and choose the option to edit the video into a Short.

After that, you can select the part of the video you want to use, add text, filters, music, or other creative elements, and then upload the final Short to your channel.

This method is useful when you already know which part of the video you want to use. However, if your video is long and you do not know where the best moments are, finding them manually can take time.

Method 2: Upload a Vertical Short Video

Another way to change a video to a Short on YouTube is to edit the video yourself and upload it as a vertical short-form video. You can cut the best part of your long video, resize it to a vertical format, add captions, and upload it to YouTube.

This gives you more control over the final result. You can choose the exact hook, add subtitles, improve the layout, and make the clip easier to watch on mobile.

Method 3: Use AI to Turn Long Videos Into YouTube Shorts

The fastest option is to use AI. With an AI video clipping tool, you can upload a long video and let the system help you find the most interesting moments. This is useful for podcasts, interviews, webinars, YouTube videos, online courses, and tutorials.

AI can help detect highlights, create short clips, generate captions, and prepare videos for platforms like YouTube Shorts, TikTok, Instagram Reels, and Facebook Reels.

If you want to save time, you can use LongToShorts.com to turn long videos into short clips with AI. It is designed for creators and businesses that want to create more short-form content from the videos they already have.

Why Use LongToShorts.com?

LongToShorts.com helps you repurpose long videos into short, engaging clips. Instead of watching a full video manually and cutting each part yourself, you can use AI to speed up the process.

This is especially useful if you create long videos regularly. One long YouTube video can become several Shorts. One podcast can become multiple clips. One webinar can become short educational videos. This helps you publish more content without filming something new every day.

How to Make a Good YouTube Short From a Long Video

Start by choosing a strong moment from your video. The best Shorts usually include one clear idea, one useful tip, one funny moment, one emotional reaction, or one interesting statement.

The first seconds are very important. Your Short should begin with a strong hook that makes people want to keep watching. This can be a question, a bold statement, a surprising fact, or a clear promise.

Keep the clip focused. Do not try to include too many ideas in one Short. A simple and clear video is easier to understand and more likely to keep viewers watching until the end.

Add Captions to Your YouTube Shorts

Captions are important because many people watch videos without sound. Subtitles can make your content easier to understand and can help improve viewer retention.

When you turn a long video into a Short, always check if the captions are accurate. Good captions make your Short look more professional and easier to follow.

Use the Right Format for YouTube Shorts

YouTube Shorts are made for mobile viewing, so vertical format works best. A vertical 9:16 layout usually looks better on phones and gives your content more screen space.

If your original video is horizontal, you may need to crop or reframe it. Make sure the speaker, product, text, or main action stays visible in the center of the video.

What Types of Videos Can Become YouTube Shorts?

Many types of videos can be turned into Shorts. Podcasts can become highlight clips. Tutorials can become quick tips. Webinars can become educational clips. Product demos can become short promotional videos. Interviews can become powerful quotes or interesting answers.

The best content is usually already inside your long video. You only need to extract the right moments and format them for short-form platforms.

Benefits of Turning Videos Into YouTube Shorts

Turning long videos into Shorts helps you get more value from your existing content. Instead of using one video only once, you can repurpose it into several smaller clips.

This can help you publish more often, test different hooks, reach new audiences, and bring more attention to your main YouTube channel or website.

For creators and businesses, this is a smart content strategy. You can create long-form content once and then use it in multiple ways across YouTube Shorts, TikTok, Instagram Reels, and other platforms.

Manual Editing vs AI Editing

Manual editing gives you full control, but it can take a lot of time. You need to watch the full video, find the best parts, cut the clips, add captions, resize the video, and export it.

AI editing is faster. It can help you find clips and prepare short-form content more efficiently. You can still review and adjust the final clips before publishing, but the first part of the work becomes much easier.

Conclusion

Changing a video to a Short on YouTube is a smart way to repurpose your content and reach more viewers. You can use YouTube’s built-in tools, edit the video manually, or use AI to create short clips faster.

If you want to turn long videos into YouTube Shorts, TikTok clips, and Instagram Reels more easily, try LongToShorts.com. It helps creators and businesses transform long videos into short, engaging clips with AI.
