Changing the video layout (Speaker view and Gallery view)
To switch the video layout during a meeting, click the Toggle tile view icon in the toolbar at the bottom of the meeting. The toolbar hides after a few seconds; move the mouse to show it again.

This switches between tile view (also called gallery view) and speaker view.

Speaker view
The large video window switches to whoever is speaking.
Tile view (gallery view)
Tile view shows thumbnails of all participants in a grid that expands and contracts as people join and leave. The active speaker gets a blue frame, so it's easy to see who's talking.
