Some users may need to replace their background while in a video meeting. For example, to hide the home environment when working remotely, or to put a suitable image in the background that fits the subject of the video lecture.
TrueConf desktop applications allow users to blur the video background. Check out our documentation to learn more about this feature and how it can be enabled. This article will show how you can change the background with third-party solutions known as virtual cameras.
A virtual camera is a program that emulates the work of a regular webcam and allows you to transfer images, video and sound from different sources. For example, users who do not want to display their webcam image may use it to broadcast a looped video recorded elsewhere to other participants in a video meeting.

The list of virtual cameras that are compatible with our client computer application is given below.
Snap Camera
