Ellie Goulding - Figure 8

From the point 0:03 to 0:09 she is walking, it looks like she is walking on the ceiling with objects attached to the ceiling and feathers falling, I think something like this would look good in my music video so I tried to figure out how it was done and I think, either that she was walking backwards, dropping the feathers then put a reverse effect on the footage. Then rotated the footage. Or she was walking forward and used a vacuum to lift the feathers from the ground and then rotating the shot. 
I like the use of both black and white and colour, how it starts in black and white then a vivid red in introduced from 0:16 to 0:19 the footage turns gradually from black and whit to colour. I really like this effect and wish to take this through to my video. However because I made need advise on how this works when editing and before filming. A similar thing happens at 1:13 to 1:14. With quick lighting changes added. 
This video has given my inspiration on how to make my mock better.
