The first clip is a Mighty Planes feature on the Airbus A380 which inaugurated Lufthansa's Frankfurt-San Francisco service.
The second clip is the Lufthansa A380 landing at San Francisco that I published in a previous post about four weeks ago. The flight crew were the same as in the previous clip and with certain similar details it is possible to speculate this might have been the actual same flight but the clip itself does not confirm that in any way.
