I dont understand why when your watching the even a live stream, like on Twitch, the video quality is very good, but when your trying to video chat with someone else the quality is so much worse. What about the two way video chat makes it so hard to get consistent hd and audio?

Most home Internet connections are asymmetric – the upload and download speeds are not the same, generally the download speed is much much faster. For Netflix this isn’t a problem because you are only downloading data, but with video chat the video quality is limited by the available upload bandwidth of the person you’re talking to. Twitch is reliant on a good upload speed for the streamer, everyone else is downloading. Twitch needs a 3-6Mbps upload speed to work well. Most consumer Internet connections are 8:1 download to upload speed ratio, so you need an approx 25-50Mbps Internet connection for decent streaming. In addition since the Internet bandwidth may be shared by multiple households, lots of video calls can quickly swamp the upload connection.
Also the cameras on a lot of laptops, are absolutely awful.
