[Getting Started] Welcome to AlphaCut! Creating Shorts with YouTube links & files

Welcome to AlphaCut! 🎉

AlphaCut is a service where AI finds highlights and turns long videos into multiple Shorts just by uploading them. Complex editing software? You don't need it anymore.

In this post, to help you get the most out of AlphaCut, we'll explain the first step: 'Video Creation and Basic Settings'.

Method 1. Create with a YouTube link

This is the easiest method. You don't need to download the video; all you need is the URL.

1. In the dashboard input field, paste the YouTube video link.
2. Click the [Convert to Shorts] button.
3. After confirming the video has loaded correctly, click the [Confirm] button.

Method 2. Upload files directly

Do you have a video that isn't on YouTube or an original file you filmed yourself (mp4, mov, etc.)? You can upload it directly.

1. Click the [Upload File] tab on the right (or bottom) of the input field.
2. Either drag and drop video files from your PC folder, or click the input field to select a file.
3. Wait a moment for the video to upload, then click the [Confirm] button.

⚠️ Caution: Do not close the window during upload!

It's okay to click other menus within the site while the upload is in progress. However, closing the browser tab (window) or refreshing will stop the upload and cancel the conversion, so please be careful.

⭐ Important: Guide for Detailed Settings During Creation

[Confirm] Before clicking the button, click [Detailed Settings] below the video thumbnail. You can set and create the Shorts length, language, segments, and more as you like.

1. Select a template

• Selecting a pre-made template will automatically apply the design.
• If you don't select one, the most recently used or saved template will be applied automatically.

2. Segment Settings

Use this when you want to analyze "a specific part" instead of the entire video.

• Slide method: By dragging the slider on the timeline, the start point and end point can be set intuitively.
• Since only the length of the set segment is deducted, you can save your credits.

3. Shorts Length

You can select the desired length of the video.

• Options: 15–30 seconds, 30–60 seconds, 60–90 seconds, 90–120 seconds. You can choose one.
• Default: If not set separately, an average of 40 seconds is the target length for automatic creation.

4. Title Language

You can choose which language to generate the Shorts title in.

• Supported Languages: Korean, English
• Default: Korean

5. Subtitle Language

You can set the language for the subtitles.

• Supported Languages: Korean, English
• Default: AI analyzes the first 30 seconds of the video and sets it automatically.

6. Speaker Tracking Mode

• This feature is optimized for conversational videos featuring two or more people.
• When this mode is activated, AI automatically tracks the speaker to provide the most immersive layout.
• ⚠️ For Pro Plan Only — This is a premium feature requiring advanced AI analysis, available only to PRO membership or higher creators.

💡 Precautions and Tips (Checklist)

Please check the following in advance for successful Shorts creation.

1. Conversion Time: Video conversion usually takes about 5–10 minutes. However, please note that the longer the original video, the longer the conversion time may be.
2. Copyright: When using YouTube links, you must be careful not to infringe on the copyrights of others, and the responsibility for using the generated content lies with the user.
