Webinar mode

A screen share with your camera overlaid, in one picture.

Webinar combines a screen share with your camera in one picture, from the panel: choose the layout (camera in a corner or side by side), the camera size, and switch between screen only, camera only or both while live. System audio can be included as with a normal screen share. Webinar is available on plans that include it, from a desktop browser only.

System audio

Yes. Tick "Include system audio" before you press Share and choose a tab or screen for which the browser offers to share audio (Chrome and Edge on Windows; tab audio on macOS). Your microphone and the system audio are mixed together; you can change the microphone or mute everything while live.
