What affects the quality of your video conferences?

During online meetings you can notice that the video resolution automatically changes from lower to higher and vice versa (e.g. from ED to HD). This depends on the following factors:

How to find out the quality of your current video meeting

To check your current incoming and outgoing bitrate, open TrueConf client application and go to Settings → System Info.


Is it possible to improve video quality manually

If you would like to improve your video quality, you could increase incoming and outgoing bitrate manually in Limits section of TrueConf client application. This is only possible if your channel bandwidth with TrueConf Server and network hardware permit:


You can see available connection speed based on bandwidth test results (Settings → Network → Test). This test simulates real network load and its results show actual loading and delay between the server and your client application. Please note that these figures may differ from what your provider claims. Recommended delay is up to 1000 ms. If it is higher, the conference participants will notice it.

If the problem persists, try the following steps:

  • use wired connection to your computer (through a network cable);
  • close other programs that are actively using network traffic or computer resources;
  • check your network hardware settings.
