... I'd like to know how the panning of some of the shots were done that seemed like the camera was floating. Probably some rig that was required to allow it to move slowly enough to allow for the time lapse. Very nice.
I'm a former Vancouverite, and know the downtown core well. I've only watched the video once.... so take this as my first impression.
Many shots were taken from bridges, as the rig moved across the bridge. The downtown core has 5 or 6 bridges (depending on how you count) that go up and over water and lead to downtown.
However, it seemed to me on first impression that at least cherry-picker would have been used.... but I'll look at it again.
As well, Vancouver is bordered on the north by the Coastal Range of mountains, so many shots could have been from North Vancouver and West Vancouver. And using a heck-a-va long lense at that. Or perhaps some of the towers on the North Shore.
Vancouver is also very hilly, with a bunch of hills and "mounts" scattered around. I used to commute 20 to 30 minutes in an east-west line (but going against traffic not with, so I was actually moving) and some days in the winter I would moves from rain to snow 3 times - each time I went from a low bit to a neighbourhood on a hill.
Vancouver also enforces "view corridors". So there are whole areas - sometimes linear - where building heights are kept low so that the mountains remain clearly visible from certain points.
Oh, and Vancouver doesn't believe in highways, so Vancouver proper doesn't have any, and the parts that make up Metro Vancouver have - oh, something like 3, 4, maybe a half-dozen... ?
So, I guess what I am saying is that its not hard to find vantage points with height to get the angles seen in the video. Vancouver has worked hard - very hard - to become and remain an attractive city.
