Looks like this (Round of 24, group E) behind the scenes video was filmed by firebathero (CN: 小火)? Not sure and I can't find the original video though. It starts off with Flash (still) measuring distances for ergonomics and probably more important these days with his wrist issues (some of the CN bullet comments are hilarious). He is also using a Qsenn DT35 rubber dome keyboard. At 10:30, I assume the guy in black is Zeus?
