Video is from the guy who filmed it. Couple of details about how long it took to film in the comments:
The first 5-6 flights was mostly figuring out what lines to take and trying stuff to see what looked nice on video. So after we had decided on a route it actually only took about three attempts to nail it, but I began to know the track really well by then.
I got a really nice onetake on flight 9, but it was cloudy so we kept filming throughout the day. This was the 16th or 17th flight.
