How to create custom Zoom backgrounds to entertain your coworkers

Show off who you are with a custom Zoom background. Here's how!

Creating a custom, AI-driven background in the Zoom videoconferencing app is a great way to hide background clutter while working from home. But with a couple of extra steps, you can go crazy with custom video backgrounds and have some fun, too!

Normally, a webcam shows just what it sees: you, your kitchen table, maybe an unkempt desk in the background. But Zoom, like Microsoft Teams, can use custom backgrounds that completely obscure all that background clutter. After enabling that background, the only thing the camera will see is your face, like this:

Zoom's AI-generated backgrounds are pretty seamless with a good PC.

We’ll show you how to enable that option and take advantage of Zoom’s built-in backgrounds. But there’s more: Zoom offers background video, too—a looping video that can replace the Zoom’s static background image. We'll show you how to select your own background video to replace Zoom’s basic options.

How to turn on custom backgrounds within Zoom

Historically, Zoom required a “green screen” to enable custom backgrounds—yes, the literal green backdrop traditionally used by movies to enable a canvas for computer-generated special effects. That changed last year, when the Zoom desktop app became smart enough to distinguish you from the objects behind you. Custom backgrounds don't seem to work on the Zoom web client, though.

Zoom has a rather complex list of minimum requirements that you’ll need to enable custom backgrounds, but here’s what they boil down to:

  • An up-to-date Zoom app running on Windows 7, 8, or 10
  • A PC with a supported microprocessor: a quad-core 6th-gen Core i5 (except a U-series chip); a quad-core 4th-gen Core i7; or any 3GHz processor with 8 cores or more.

If you don’t know what you have, don’t worry. This is all simple enough that it will either  work, or it won’t. Virtual backgrounds are also available for iOS (with an iPhone 8, 8+, or X, or an iPad Pro and the 5th and 6th-gen iPads) but support for Android isn't listed.

When the Zoom main screen opens up, you’ll see the Zoom main page. The first thing to do is to click the Zoom Settings gear in the upper right-hand corner. This opens up a wealth of options, but the relevant one for us is the Virtual Background option.

The gear icon hides Zoom's Settings menu.

Zoom makes this step extremely easy. By default, Zoom turns on your webcam, and you should see what others in your chat will see: you, and your background. But if you click one of the images below your video window, you should see what’s behind you replaced with either a static image (the Golden Gate Bridge is a favorite) or else a slowly looping video background, like the northern lights or Zoom’s beach scene. (As you might expect, video files have a small camcorder icon in the corner.)

As you can see from the screenshots, there is an option to enable a green screen, if you have one. But on my test machine—the recent Surface Pro 7—I certainly didn’t need one.

The background feature isn't perfect: The background sometimes obscured my collar, and Zoom isn’t always friendly to those who talk with their hands. Zoom also recommends that you don’t wear clothes that are the same color as your background.

Zoom will arrange your available backgrounds beneath the video window. The Zoom client does a pretty good job of distinguishing my navy-blue sweatshirt from the dark background, too.

How well Zoom distinguishes you and applies the background correctly appears to be both a function of your webcam and your computer’s processor: The better they are, the more accurate the result. But you should be able to tell in a flash if the results are acceptable. 

How to create a custom background in Zoom

Creating a custom background in Zoom is child’s play, honestly. If you click the small “+” icon, you’ll have the option of selecting either a static background or video file. Picture file formats supported include BMP, JPG, and PNG. With video, you’ll have the options of MP4 or MOV. You’ll need either a background image with an aspect ratio of 16:9 and minimum resolution of 1280x720 pixels, or a video file with a minimum of 480x360 pixels (360p) and a maximum resolution of 1920x1080 pixels (1080p).

Selecting a static image is especially easy. Recent Zoom calls among PCWorld staffers have included background images of Bridge A from Star Trek's U.S.S. Enterprise, and the Oval Office. Zoom recommends that you pick a copyright-free image, but the company doesn’t seem to enforce it.

Once you select an image or video file, Zoom adds it to the visual index of virtual backgrounds within the Virtual Background setting menu.

How to create a video loop as a custom Zoom background

But what if you don’t want to use Zoom’s preselected clips, and want to create one of your own? If you’d like to use an existing video file, of course, we’ve just shown you how to do that. The other way is to take an existing file and trim it down, keeping just the content that you want to show off.

How you get the file is up to you; we have an in-depth guide on how to download videos from YouTube, but you may already have video files on hand that will suffice. In any case, you'll want to whittle it down to a short, looping clip. Fortunately, there’s a simple video editor already within Windows that makes this very easy.

If you do end up downloading a YouTube video, you can use the low-quality option for background use and file size. You'll also be trimming it down so you're just sampling a small clip.

Video Editor is a relatively new addition to Windows, though it’s closely tied to the existing Photos app—in fact, you’ll see “Photos” in the header, rather than “Video Editor.” Video Editor is basically a slimmed-down version of Windows Story Remix, a 2017 app that quietly faded alongside Windows’ mixed-reality effort.

When you open Video Editor, you’ll want to select the button that asks you to open a new video project. That will take you to this screen, titled Video Projects:

Once you've loaded your video file, trim it using this button.

In the Project Library box, click the Add button and select your video file. The clip will then appear in the Project Library. You’ll then need to drag it down to the Storyboard, below, and into the first box. It’s here that you can add all sorts of effects to your video, but for our purposes we only need one: the Trim feature.

The Trim screen allows you to use the two trim markers to the left and right to define where your clip begins and ends. You can use the Seek pin to help you set the defined limits on either end. (Remember, Zoom will loop the end of the trimmed video back to the beginning.) Click Done when you’re finished.

Adjust the length of your video clip using the Trim feature. Remember that you're going to be looping the video, so select just a small portion of it.

Video Editor will then take you back to the Video Projects box, where you’ll want to click Finish video to save and export your video. You may as well save it in 1080p quality, though you’re certainly free to choose another format. Remember, this is a background video, so the quality doesn’t have to be top-notch.

From here, you’re essentially done. Open the Zoom app again, even if you’re not connected to a meeting, and double-check that your video looks the way you want. Remember that a video background may annoy your coworkers—even if that’s the intent!—so you may want a calmer, more businesslike background as a secondary option.

In any event, it’s fun just to explore, create, and develop a background to suit your mood or the situation. You can use a custom background to define your sense of personal style—after all, chances are your coworkers won’t really see what you’re wearing, anyway!

It really doesn’t get more “gaming laptop” than this.

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
