📢 Pro Tip: Fix "Cropping Blur" with AI Super Resolution

When you crop a horizontal video to vertical, you lose a lot of pixels, which may make the video look "soft" or blurry. If your exported video isn't sharp enough, go back to VideoProc's main menu and use the AI-powered Super Resolution tool. It will intelligently rebuild the missing details, ensuring your cropped vertical video looks like it was shot in native 4K.

Bonus: Make a Horizontal Video Vertical without Cropping

As said, VideoProc Converter AI also supports turning horizontal videos into vertical by adding black bars. Here's how:

Step 1: Download, install, and launch VideoProc Converter AI. Click Video Converter, then import the horizontal video file or files you want to convert.

Step 2: Select H.264 MP4 as the target format. It is widely supported across social media platforms and devices, although you can choose another format or codec if needed.

Step 3: Click the gear icon to open the Format settings panel. Go to Aspect Ratio and select 9:16, or another vertical aspect ratio that suits your needs. Then choose a matching output resolution.

For example, if the original video is 1920 × 1080 in 16:9 and you want to convert it to 9:16, select 1080 × 1920 as the output resolution.

Check Expand Video to preserve the entire original frame without stretching or distorting the image. Because the horizontal video is being fitted inside a vertical canvas, black bars will appear at the top and bottom.

Best for: Social media creators who want quick AI-powered automation.

CapCut, developed by ByteDance (the company behind TikTok), is a popular video editor on both mobile and desktop, known for its fast, AI-powered tools. One of its most useful features for social media is Auto Reframe, which uses AI to track your subject and automatically convert horizontal footage into a vertical 9:16 format. If you'd prefer not to crop the video, CapCut can also use AI to expand the background instead. Just note that both Auto Reframe and AI Expand are part of the CapCut Pro plan, which costs $89.90 per year. CapCut works on both PC and mobile. Below, we'll use the mobile app as the example.

Step-by-Step: Convert a Horizontal Video to Vertical in CapCat

Method 4: Make Horizontal Video Vertical by Expanding Background

Best for: short video clip with very simple background.

This is a newer way to turn horizontal footage into vertical. Instead of cropping or adding a background, AI background expanders expand the frame by generating new pixels at the top and bottom based on the existing image. They analyze the scene and predicts what the missing areas should look like, then fill them in to match the original video. The main advantage is that your framing stays intact, with nothing cut off and no need for blurred sidebars, so there’s no direct content loss. However, because the added areas are AI-generated, results can vary. It tends to work best with simple backgrounds, while more complex scenes may show slight inconsistencies, unnatural textures, or minor distortions near the expanded edges. There are many AI background expanders available. Below I use AtLabs and show you how to make a horizontal video vertical using it.

Step-by-Step: Convert a Horizontal Video to Vertical with AI Background Expander

Step 1. Open the re-frame tool of AtLabs on your browser. Hit Upload and select your original video for loading to this online horizontal video to vertical converter. Note: The maximum video size you can upload to AtLabs is 100MB and 30 second.

Step 2. Choose 9:16 or any other vertical aspect ratio you want. If needed, you can enter text prompt to guide the VEED generating new pixels.
