In the ad, Nokia shows off the PureView's image stabilization technology. The opening segment... shows a young man and woman cheerily riding bikes along a scenic river. As he films her breezily laughing, the ad shows side-by-side video — obviously intended to represent the phone's video capabilities. On the left, Nokia shows the non-stabilized version, which, predictably, looks terrible, and on the right the ad shows the perfectly smooth capture, purportedly enabled by Nokia's optical image stabilization technology. The only problem is that the video is faked.
As you can see in the video and photo above, there's a curious reflection in the window of the trailer in the background. It's not a young man riding his bicycle alongside the cheerful model, but instead a big white van with a lighting rig and a cameraman standing in the doorway — with what appears to be a large camera rig. Whatever he's holding, we can reasonably agree it's not a Lumia 920.
