Resolving Video Quality Issues (Mac)

There are a number of factors that can affect the video quality in a videoconference. For example, if the video is choppy, flickering, or the other person's actions appear blurred. Review the lists below to understand some of the more common issues and how you can resolve them.

Your internet connection might be causing quality issues

  • Test your internet connection using a third party tool (e.g.,,
  • If the videoconference is trying to use more bandwidth than your connection allows, there might be video issues. Check your bandwidth usage and if necessary change the maximum usage.
  • If you are connected via a wireless connection, you can improve the quality in most cases by using a wired connection.
  • Avoid sharing a connection with others, another application or another computer that is streaming video or file downloading (this consumes bandwidth).

Your computer might be running slowly

  • Your computer might have apps running in the background that use up its processing power and/or bandwidth. To free-up your computer, close all applications except those needed for your video visit. (For example, shut down email apps which can use a lot of bandwidth when downloading large attachments.)
  • If you’re using a laptop that is running on battery power, you might have problems with video calls when it uses "power saving" mode. Plug your laptop into a power outlet or switch your computer's power mode to "maximum performance".

It's better to use a USB port on your computer

  • Plug the webcam directly into one of your computer’s USB ports whenever possible rather than a USB hub (whether the hub is one you added to your computer, is built into your flat panel monitor, or is built into your laptop’s docking station).
  • If you must use a USB hub, it should be externally powered for the device to perform well.

If the video is dull or dark, it might be because there is not enough light

  • Good lighting is important for a good quality videoconference.
  • Use a desk lamp to enhance overhead lighting. The extra light helps to lessen shadows and smooth skin tones.
  • Avoid sitting where there is a bright light behind you. For example, do not sit in front of a window.
  • For best results, the light source should originate from behind the webcam and shine on your face.
