Setting the resolution will automatically change the resolution on any current and future calls. If you have a high-speed connection and want maximum webcam quality, set this higher. If you're working with a relatively poor connection, set your preference to a lower resolution to reduce latency on the call. The settings correspond to the following resolution: * Low: 160x120 * Medium: 320x240 * High: 640x480 ### When in a call: #### Enable my webcam automatically When this setting is on, Tuple will automatically share your webcam video when you join or start a call. #### Show preview before sharing If selected, Tuple will ask you to confirm a preview of your webcam before sharing. If deselected, clicking the "Share Webcam" button will share your webcam immediately. ## Background blur and video effects On supported Macs, macOS includes free background blur and other camera effects that work with Tuple. While your webcam is active, open the camera indicator in the menu bar and enable **Portrait**. On macOS Ventura, open **Control Center**, click **Video Effects**, then enable **Portrait**. Availability depends on your Mac and camera; see [Apple's requirements](https://support.apple.com/105117).
