Help: What are the keys to a high quality webcam stream?
There are many ways to improve the quality of your webcam broadcast.
First of all make sure you have a good internet connection with enough bandwidth. You can check how much bandwidth you are getting through e.g. www.speedtest.net.
To improve your quality even more you can get Premium and use different kinds of stand alone apps such as Wirecast, VidBlaster or Flash Media Live Encoder
These applications provide you with more quality options and there are many tutorials about those applications on their respective sites.
At last, some basic recommendations. Lowering the quality setting or video bitrate will improve video smoothness. If your picture quality is poor, you may consider investing in a higher quality camera. Also try adjusting your lighting. Digital cameras need a lot of light, and video will begin to appear grainy in dark conditions.
