Living not 20 minutes (RV TIME) from the falls I know this procedure well. The procedures put in place about 10 years ago was due to a mix of helicopter and fixed wing traffic, 2 helicopters hit each other, one made it down safe, the other all parshed.
Fixed wing aircraft were restricted a 1000 ft even higher (go figure), the helicopter companies have approved patern that they must follow, they got the lower 1000ft. The cross wind points are the rainbow bridge and the railway tracks, your video looks a tad bit tight there. There are designated entry and exit points.
IMPORTANT TO UNDERSTAND
Buffalo and Erie can not approve flight into this area, be careful to think you had approval from them, they have no say what so ever, you are VFR. It is your responsibility to ensure you do not violate airspace. No harm done, but this is usually a HEAVY traffic area with a lot of aircraft in close to each other and everyone is expected to be following the procedure.
In Canada, VFR flight plans or itineraries are manditory beyond 25 NM from destination. In Canada airports are far more spread out. If you have an emergency, these flight plans are your life line. When I fly in the US, which is quite a bit, I joke about having an airport to land at every 5-10 miles. Here in Canada, well north of Toronto anyway, most of Canada's airports can be hours apart.
If you land in Canada (Customs), make sure you have to 2 hours prior notice, the US (Customs) is becoming more in tune with this 2 hour requirement, including Buffalo now. This is hard to work with being 30 minutes from the border.
