It's obviously fake without even having to watch the video and analyze for editorial mistakes. If this were real, it wouldn't be amazing because they built wings for a man that allow him to fly... it would be amazing because they built a machine that defies physics. The man obviously can't run fast enough to build up a vertical lift force, nor are the wings designed for that. This motion of the wings seem to insinuate that the "normal" force of the air against the flapping of the wings produces enough reactionary force to lift the man, as is with the case of most birds during takeoff. However, in birds, the motion of their wings returning to the upwards position is designed to reduce a the amount of force pushing back down to create a net upward force, resulting in liftoff. This apparatus does not accomplish that since the movement up and down is almost identical, creating a near zero sum of forces... let alone achieve the rate of liftoff that was implied in this video. I don't even have to do the calculations to know this is 100% fake.
