My motivation was thus: I'm not a video transcoding guy. I just wanted to know a 10,000 ft overview. My summary is what I got out of a very detailed technical article (and it took me a minute to find the comparison pictures in the article, so hopefully re-posting the highlights saved others time). Another way of looking at it: People hyper-summarizing articles are like HFT for news aggregators. It makes the aggregator more efficient by cutting to what many people only want to know thereby increasing their capacity to consume even more knowledge irrelevant to their lives.
