Tanking up with oxygen – view from above

ATV Georges Lemaître has delivered its 100 kg of oxygen to the International Space Station as reported via the ATV Control Centre during the first, second and third transfer from ATV-5's tanks to the Station. After questions on Facebook the team at ATV Control Centre even took time to explain how the amount of oxygen released is calculated. But how does an oxygen transfer work for the astronauts on the International Space Station? ATV-5 loadmaster and ESA astronaut Alexander filmed the process from his weightless abode for our viewing pleasure:
