This guy is totally right. When there's no change on screen a huge percentage of bandwidth is from iframes, essentially start over points for fast forward and network corruption. There's a tradeoff between skip/fast forward fidelity, streaming delay, and iframes. If you're not live streaming and don't care how easy it is to skip around the video increase the iframes inverval as much as you want and watch the bitrate melt away
