Restart your computer before a call.  Other applications might be using computer power or have access to your camera or microphone. Restarting your computer will ensure your computer is ready for video. 

Use fast Internet with an Ethernet cable. Video quality changes with Internet speed, so the faster your connection, the better the quality of your video will be. 

Use a newer computer with plenty of processing speed. Sending and receiving video takes a lot of computer power. Old or slow computers will have a harder time processing the video, which can cause choppiness. 

Use low resolution. If you are experiencing poor video quality, try lowering the resolution. Using LD or SD requires less bandwidth and computer power than using HD, which will mean less choppiness during your call. 

Use headphones. Your computer will usually automatically eliminate echo or audio feedback so you don't hear yourself talking. But if it happens, both you and other participants in the call using headphones should solve the problem.
