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.
