 For instance, in a group call where seven participants have their video cameras on, on each client page you can select two participants' videos are displayed at higher resolutions. These two participants set to show their video at 720p by setting their views on the web page to be 720 pixels in height by 1280 pixels in width (or greater). The remaining five participant videos should be set to a lower resolution, such as 360p or lower.

    Simulcast isn't supported on all browser devices. Currently, simulcast is unavailable when sending videos on mobile browsers or macOS Safari. If a participant attempts to render 720p video from a user on iOS Safari, Android Chrome, or macOS Safari and another participant on the call tries to render the same video at a smaller resolution, both receive the smaller resolution. This change happens because the devices prioritize smaller resolutions when simulcast send isn't supported.
