Emirates A380 do use that exact airport (and google earth images show it is the same airport). The drone turning around reveals the same coral bay and everything is correct. The last few seconds the small island off to the side, the housing area (blue bay) and lakes are clearly visible.
This puts the drone roughly 7000ft from the threshold and roughly 1000ft off to the side of the extended centreline.
An A380 which isnt full is surprisingly powerful. It doesn't need masses of runway. That airport has 11056ft ft available for takeoff and an absolutely fully loaded A380 requires 9500ft. Thats more than plausible on the video. Measuring on google earth he uses about 8000ft of runway to get airbourne.
So yes, the drone footage is definitely that airport and yes A380s routinely operate from there and yes they could easily be airbourne with 1/3 of the runway or more remaining depending on load and conditions.
A few other things, the time from rotation to passing the drone is 23 seconds. Assuming an increasing but initial rate of climb of about 2000ft/min that means its more than plausible for the drone to be at the height the plane goes (its way under 1600ft drone maximum).
So everything in that video is possible. The ONLY thing im not sure of is the odd reflection and lack of heat haze as it passes.
EDIT:- This is it on google earth:-
Google Maps
3D view can replicate that drone view exactly, ruler tool for measurements.
