From July 15, 2022, Zoom will have a 40-minute limit even for meetings with two participants if you have a free subscription. (Previously, it was only for meetings with 3 or more people.)
Companies and organizations using Zoom for business should consider switching to a paid license at this opportunity. 

When using a Zoom meeting at home or in a neighborhood cafe, we recommend using the “virtual background” function, which allows you to hide your surroundings.

In this article, we will introduce how to use the “background blur” that is installed as a new function of the virtual background.

If you can’t blur the background, the causes and solutions are also summarized, so please refer to them as well.

Next, let’s look at the operating procedure for actually blurring the background for each device.

Enabling the virtual background feature

Since the background blurring function is a kind of virtual background function, it is necessary to activate the virtual background function first if you want to use it.

To enable the virtual background feature, follow the steps below.

  1. Sign in to the Zoom web portal (https://zoom.us/)
  2. Select “Zoom webinar window smaller, other options will move to [ Details ]. There are also new Settings” on the My Account page
  3. Turn on the “Virtual Background” item

If you have a contract with a paid Zoom license, you can enable and set virtual backgrounds for each account and group in addition to each user.

Blur the background with the desktop app

There are two ways to blur the background on the computer version of Zoom: applying blur in advance and adding blur settings after the meeting starts .

To set background blur before the meeting starts

  1. Launch the Zoom desktop app
  2. Select “Settings (gear icon)” on the home screen
  3. Select the “Background and Filters” item
  4. Click “Blur” in the list of virtual backgrounds

When blurring the background during a meeting

  1. Launch the Zoom desktop app and start the meeting
  2. Move the cursor to the toolbar at the bottom of the screen
  3. Select “^” to the right of “Stop Video”
  4. Select “Choose a virtual background” (or “Choose a virtual background”)
  5. Click “Blur” in the list of virtual backgrounds

Blur background in mobile app

  1. Launch the Zoom mobile app and start the meeting
  2. Tap the toolbar at the bottom of the screen after the meeting starts
  3. Tap “Details” at the bottom right of the screen
  4. Tap on “Backgrounds and Filters”
  5. Tap “Blur” in the list of virtual backgrounds

remove blur

You can cancel the blur by moving to the virtual background selection screen again and selecting “None” from the virtual background list.

You can change the blurring on or off at any time, so it’s a good idea to use it properly according to the location and the person you are meeting with.

Causes and solutions when the background blurring function cannot be used

Causes and solutions when the background blurring function cannot be used

If the function to blur the background is not displayed or cannot be selected, the following causes are possible.

Old version of Zoom

The blurring function was added to Zoom’s virtual background function since version 5.5 of Zoom .

Therefore, if you cannot find the blur function even after following the above steps, it is possible that the version of Zoom is older than 5.5.

Check for Zoom updates by the following method, and update to the latest version if an update is available.

  1. Click the user icon in the upper right corner of the home screen of the Zoom app
  2. Click “Check for Updates”
  3. If “Updates are available” is displayed, click “Update”

For smartphones and tablets, you can check for updates and perform updates on the App Store (or Google Play).

Insufficient device specs

If the blur function is displayed but cannot be used, it is possible that the device using Zoom does not meet the system requirements.

In addition, it seems that there are cases where the load on the device is reduced by terminating applications other than Zoom, and the blurring function can be used normally.

summary

summary

  • From version 5.5 onwards of Zoom, a function to blur the background has been added as one of the virtual background functions.
  • The background blurring function is available on both desktop and mobile apps
  • If the background blurring function cannot be used, it may be solved by updating Zoom etc.
