By default, Amazon Chime crops all video tiles during a meeting. Amazon Chime does that in order to include more tiles in the meeting window. You can undo that cropping whenever you display your video tile. Un-cropping changes your tile's aspect ratio to 16:9. Only you see the change.
To uncrop your video tile
On the Call control bar, open the Video menu (^).
Choose Show me my self view uncropped.
Repeat these steps to crop your video tile.
