Video Kinect is not smooth, or the video is not working
Video Kinect is smoothest when you have good room lighting. If the video is not smooth, try increasing your room lighting. Another possibility is that your Internet connection isn’t fast enough. Video Kinect works best if you and your friend have a high-speed Internet connection (at least 540 kilobits per second or Kbps). For the best performance, an upload and download speed of 700 Kbps is recommended. See Improve Xbox LIVE Speed for help.
Video works, but there is no audio
If you're using a Kinect sensor to chat, make sure that you disconnect any wired or wireless headsets. Video Kinect works best if you and your friend have a high-speed Internet connection. If you are still having problems, see Troubleshooting problems with chat.
Video Kinect is blocked for this profile
Video Kinect can’t be started if a profile subject to parental controls is signed into your console (child accounts are restricted from Video Kinect by default). To change online safety settings, see Online safety and privacy.
"Xbox LIVE Gold Membership required"
If your gamertag has an Xbox LIVE Gold Membership and you get this message, exit Video Kinect and try starting it again.
Can't see all of your friends
You will only see Xbox LIVE friends when they are online.
Do you have more than one Microsoft account? If so, try signing in with your other account to see if your friends are associated with that account. If you want to change the Microsoft account associated with your gamertag, see Manage your Microsoft account.
