When you call someone or have a meeting using Webex App, the video resolution adjusts as the network bandwidth changes. The environment affects the resolution, but you get the best quality possible from the current network conditions.
You can refer to these specifications to get information about the supported codecs, video definition, and bandwidth usage in Webex App.
We optimize the quality by using the Opus codec for audio and the OpenH264 codec for video.
Supported video definition
The video resolution varies depending on the type of device that you use:
Webex App supports 720p high definition video calls on Mac, Windows, Android, and some iPhone and iPad devices (iPhone 4S and later, iPad Air and iPad Air 2, iPad Pro, and iPad Mini 2 and above).
For Web (Firefox) and other iOS devices (such as the iPad 2), Webex App supports 360p standard definition video calls.
Approximate bandwidth usage in Webex App is:
700 kbps for 360p video calls and 1.5 Mbps for 720p video calls.
80 kbps for calls with video disabled or audio-only calls in iOS 10.
