There are 2 videos at the airport. Maybe we should be clear about which is being talked about.
One video contains a "HLN" overlay in the middle of the screen, which
@flarkey posted sourced from the nu.nl website. It is also on the
HLN website:

This shows a view from the near/in what appears to be the old air traffic control tower integrated into one of the airport buildings, labeled "TWR (backup)" on this diagram at opennav.

~5 seconds in, a distinguishable roof feature is seen which locks in 1 line of sight.
There is another video linked to by
@UAV Hive, uploaded by outlet
NieuwsbladOnline, which is filmed from a different location, facing a different direction, initially facing towards an area that appears to be used by cargo planes, not near the main terminals. An Air Belgium plane operated by Sichuan Logistics registered as OO-LFC is visible on the ground at the start. I do not think it is possible that this was also filmed from the old ATC tower. The line of sight onto the building and light poles does not work. It has to be somewhere with a more westward line of sight onto the building, in a position pivoted counterclockwise
around OO-LFC.
It's from another publication in Belgium on YouTube:

Incidentally I fear with HLN that it's muted the audio on their videos to prevent the rotor noise being heard, they've compressed their videos down so much it's impossible to recover any detail from the shadows. Great for the clicks but not for analysis....
I am also revising my previous location for the camera for the
NieuwsbladOnline video, from the parking deck, to instead be in the office building at around 50°53'54.29"N, 4°29'2.35"E. The western most corner, but probably the southwest face of the building.
Here are what I think are the two locations and lines of sight, onto the building+Sichuan Logistics plane in the
NieuwsbladOnline video, and onto the step in the roof 5 seconds into the
HLN video. These locations are far enough apart that they were either filmed moderately far apart in time, or were filmed by different people.
