What’s video resizing?

Video resizing involves using an editor to adjust the dimensions of a video for specific purposes. This typically involves altering the width and height; however, with some tools, you can also change a video’s aspect ratio.

The more ways you can use a video, the more value you get out of each piece of content. For example, you might resize a video so that you can post it in different formats, such as a large version for a sidebar ad and a vertical 9:16 format for a social media post.

Learning how to resize videos allows you to:

Tailor videos to each use case
Reduce file sizes so that videos can be more easily stored and shared
Enhance video upload speeds
Improve viewing quality

How to choose the right video resizer platform

To get the most value out of your video editor, you’ll want to consider:

Ease of use: Inexperienced editors should focus on platforms with user-friendly interfaces and plenty of documentation. It should be easy to perform basic tasks, such as cropping and compression. Even advanced creators can save a lot of time by working with an intuitive dashboard.
Device and format compatibility: The tool you select should work on the devices you use most frequently and support popular video file formats, such as MP4 and MOV. This is especially important if you have a full video content team working with a variety of formats and devices.
Processing speed: Whether you’re working at scale for an enterprise or simply resizing for a few social media posts, waiting around for a video to process and upload takes time. The faster your tools work, the more efficiently you can get content out to your audience.
Pricing: Costs vary widely among video editing platforms, from free plans to custom enterprise pricing. When selecting a platform, consider your budget and whether you plan to scale.
