As with any real-time web videoconferencing system, our system will adapt to changing network conditions and resolve minor glitches without harming meeting quality. More severe connectivity glitches may appear as any of the following, and may require additional troubleshooting:

  • frozen video
  • low framerates
  • lower image quality
  • audio and video out of sync

If you experience issues with poor video or audio quality, you can check-out our Diagnose Your Network with Ping, Traceroute, and Speedtest article for testing and diagnostic suggestions.
