If you experience poor quality while attending a video conference, here are a few tips participants can follow to improve video quality during a webinar.

  • If possible, use a newer computer with plenty of speed – Sending and receiving video takes a lot of computer power. Old or slow computers will have a harder time processing the video, which can cause choppiness.
  • Restart your computer – Other software might be using computer power or interfere with your video or microphone. Restarting your computer will assure your computer is ready for video.
  • Close unused apps and avoid other activities that steal bandwith – Close background apps or browser tabs before starting a session to lighten the load on your device, and make more computer power available. Avoid large uploads, downloads and cloud back-ups during the session. Choppy video during a call can also be caused by CPU over-throttling if your computer is handling multiple tasks at a time. You can check by opening Task Manager on Windows or Activity Monitor on macOS. View the CPU tab, and check to ensure it isn’t at 85% or more as that could cause issues.
  • Reduce the video quality in Zoom video settings (if you are displaying video)- Low definition is best for older devices and slower connections.
  • Move closer to your wifi router, and switch to the 5GHz frequency (if available on your router) – This will increase the maximum amount of bandwidth available to your device over a shorter distance.
  • Use an ethernet cable connecting your computer to the router – This will provide the most stable connection possible.
  • Turn off other devices on the same wifi connection are using high bandwidth activities (e.g., Netflix / Youtube / Skype / FaceTime)
  • Ensure your router isn’t physically obstructed or out of view – Keep it in the open, and the signal will be stronger.
  • Disable lower power mode on battery powered devices or keep your device plugged in – Some devices reduce functionality to save power when the battery falls below a certain threshold, often called “low power mode” this can cause reduced performance.
  • Turn off your corporate VPN if it’s not required for the meeting.
