Part 2. Limitations of Using Online Croppers

1. Most of them cannot frame key objects, which means some important objects would not be in the frame that online tools generate. As some of these online tools are mostly automatic online croppers and video resizers, you have no power over how the video comes out in the end. Some of them will not be accurate and may cut out a frame you want, and some might even leave frames you don’t need.

2. Some of them cannot auto-resize the video for different platforms. After looking at our list of tools to crop video online, you will see from the pros and cons that some of them possess the ability to resize video online to certain platform preferences while most of them can’t. You can only select from their own preset, which may or may not suit the platform requirements in the end

3. Some would leave the black bars on video. This point is almost inevitable in all video size converters online; after cutting and/or resizing the video, they leave some black bars on the edge of the video, and it might not go away even if you try to resize it again and again.

4. Upload speed is slow in most online converters. When uploading the video or processing the tools to resize video online, the processing speed is almost always slow.

5. Online tools support limited video formats. This is a given truth. They can’t hold just about enough resources for one to fully enjoy them. Online tools are like quick solutions to video editing problems. Most of them don’t contain complex formations like supporting multiple formats, etc.

Part 3. A More Intelligent Way to Change Video Frame Size

As mentioned above, online tools are quick solutions to video editing problems, so if you need a more comprehensive solution for video editing, then standard software is the best way to go. Here we recommended one of the kings of video editing; UniConverter.


This is one of the most hailed video editors of all time. It always stays ahead of the competition every time by bringing in new features and tools. Originally containing popular video editing tools like converter, video compressor, merger, video editor and effect, screen, voice and webcam recorder, DVD burner, video downloader, etc. Now, it brings new features like watermark adder and remover, background remover, intro, outro maker, and lots more others; let’s not forget Auto Reframe. Auto reframe is the automatic video cropper and resizer for UniConverter. UniConverter’s auto reframe tool features a series of options that makes video cropping and resizing very easy for you. It has a bunch of preset aspect ratios, most of which are made for uploading on video sharing platforms like YouTube, Facebook, TikTok, VEVO, etc.

Steps to Crop and/or Resize Video on UniConverter with Auto Reframe

Step 1 Launch UniConverter and Select Auto Reframe

Unlike the other popular tools placed in their area, Auto Reframe is located in the Toolbox tab. Launch UniConverter and on the main interface, look to the left side of the screen and locate Toolbox. It should be the last tab on the list. Once you click on it, the screen changes and reveals some other tools. Click on Auto Reframe. You should know that Auto Reframe only comes on the latest version of UniConverter, so if you don’t have that, you need to update your UniConverter software.

Step 2 Upload your video and Cut/Resize

When you click on Auto Reframe, a new window pops up, which allows you to upload your video. Click on the purple folder in the middle to choose from your local disk. When a video has been uploaded, the features on the right side become active, and you can set the aspect ratio and speed of the video. All formats supported by UniConverter are assigned to one or more platforms. You just need to know which one goes for which and select accordingly.

Step 3 Analyze Video and Export

When you have selected an aspect ratio, be sure to preview your video to see if it fits your preference but first, click on analyze to apply the changes you have made. Every time you make a new change to the video, you need to click on analyze to save the settings before previewing or going directly to exporting. To save your file, click on Export at the bottom right corner of the screen.

If you are not satisfied with any of the preset aspect ratios, manually change it by checking the Adjust Frame option. A box will appear on the video preview, and it can seize the key object in the video, so you can keep the main content in the new frame.
