In Gather, when your avatar approaches others, a video call automatically starts between you and the people you approach. All videos will initially appear at the top of your screen. In an open area, you will be connected to everyone within 5 tiles unless you activate Quiet Mode. When you are in a Private Area, you will be connected to everyone who is also inside of the private area.
When there are multiple participants in one gathering, a select number of video call windows will be shown at the top of your screen. The number of video participants shown depends on the size of your browsing window and resolution of your screen.
You can scroll between the videos manually by clicking the arrows to the left and right of the videos shown. This is called the "video carousel".
To increase the number of videos visible to you or to enlarge the videos you are currently seeing, you can enter Grid View. Grid View will display up to 9 videos in a grid format at the same time with their names and avatars visible. To exit Grid View, click button in the upper right of your screen with the arrows pointing towards each other.
When someone first joins your an on-going group conversation, they will appear at the end of your video carousel. Whenever they speak, their video will be brought to the front of your carousel if they aren't already visible on your screen. This helps sort the videos you see such that the most active contributors to a conversation will automatically be brought to the front of your carousel.
