I tried it with the strobe in FCP and added a bit of motion blur (16 frames - blurriness 800).
Kinda looks like it, but I would say it's the camera that gives this special blur. Looks like they just filmed it at a lower shutter speed.
This seems to be shoot with a low shutter speed.
I would speed the picture up a 50%.
Then slow it dow a 50% WITHOUT FRAME BLENDING.
The movie will look as shoot as half the fps.
Apply a lot of Movement Blur (ReVision MB or similar).
