Hi, My fiancee is away and we were facetiming when she noted that the video quality looked much better when I was using my iPhone 6 compared to my 2014 13'' rMBP. So i decided to test it out at home and called my iPhone from my mac, and yes the video quality of the iPhone is MUCH higher. I can see that the data stream is around 40-80kb/s coming from the rMBP and 220kb/s coming from the iPhone. Both are connected to the same wifi network. I tried Skype and the rMBP looked great and sent out at 200kb/s, so I know it's possible for the camera to do better. I just don't get why the quality is lower when using Facetime and why the iPhone is able to do it at such a higher quality? I'm on El Capitan latest beta build but restored to Yosemite to test it out and had same results.
