Troubleshooting video performance in Zoom

Troubleshooting video performance in Zoom

Option 1: Outgoing Video

Streaming video from your side to Zoom may not be available for two reasons, the second of which needs special attention. In particular, restrictions on the operating system side are the most frequent problem, since the application in question simply cannot detect the camera.

Cause 1: Camera disabled

The most obvious reason for outgoing video not working is that the camera is disabled through the program settings via the corresponding button on the bottom panel. The situation can be corrected by pressing the button "Enable video" button. on any platform and confirming access to the linked component. In either case, the camera image will appear on the screen.

Also, pay attention to the possibility of the conference organizer forcibly suspending the video, albeit without automatic mode, as is done with the microphone. Thus, the video can be blocked by the session administrator for some reasons, which cannot be avoided by internal or external means.

Reason 2: Third Party Restrictions

The most extensive topic is that of third-party restrictions imposed on the application by the operating system itself or related to camera malfunctions. To get started, if you're using a mobile device or computer running Windows 10 or later, you need to visit your privacy settings and allow the camera to be used by everyone or by a specific app.

If the above action has not resulted in anything, you should use any other program to check the device and only after that move on to more radical solutions. As a last resort, you will have to replace the camera if the image does not appear in any other application, or at least reinstall the application if the result is more favorable.

Option 2: Incoming Video

Blocking of incoming video on Zoom is quite a rare issue as the messenger mainly takes care of video and audio related features to work. If you encounter such a situation, the problem is most likely due to the app malfunctioning or accidental activation of one of the internal functions.

Cause 1: Incoming video is blocked

Through the settings of the integrated camera, which are available to all conference participants without exception, it is possible to forcibly block the incoming video signal, which is useful in case of traffic savings, for example. This option is only relevant if a static image is still displayed instead of the caller's photo after turning on the camera.


  1. To disable the above option in the desktop version of Zoom, open the main window of the program, click the tab «Home» tab. and click on the gear icon. A similar section can be opened directly during the conference by selecting "Video settings". in the dropdown above the element “Start/stop video”.
  2. If necessary, manually click the tab "Video". through the menu on the left of the configuration window and scroll to the bottom of the page. Here you have to uncheck the checkbox "Activate the incoming video stop function.".
  3. No need to manually save new settings, all changes are applied in the background. Also, if the parameters were edited during a communication session, you can see the result immediately.

  1. A significant difference between the mobile app and the desktop version of Zoom is the limitation of settings, making it impossible to change the parameter in question outside of the conference. Therefore, the first thing to do is connect to the session and only then proceed to the software configuration.
  2. Once you understand the connection, on the right side of the bottom panel, pull down the menu "Advanced". and go to "Conference setup".. To disable the parameter in question, use the slider "Stop incoming video.".
  3. You can only verify that the participants' video stream works by joining a conference with other users. If you have previously accessed a suitable channel, the changes will take effect as soon as you exit the specified settings section.

Reason 2: Software failure

A more global problem, often affecting many functions at once, is the messenger malfunctioning, for example caused by an update. The solution in this case is a complete reinstall of the app and the deletion of all user data, regardless of the device.
