Based on the video at the bottom of the page, I'm not really impressed with the video quality. Sure, it might be "1080p" but it still looks pretty fuzzy
Yeah; I like the idea of it, and certainly concessions have to be made for the size, but it really does look jarringly bad when they switch from the high quality shots (using something else to record), to the footage presumably taken by the Cube itself.
Not only does it look kinda fuzzy and janky (like the actual recording frames per second is quite low), but the shot where they show a loop under the bottom of a bike (at ~0:25) has probably the worst chromatic aberrations I've ever seen and I've handled some old lenses with bad chromatic aberration. It is like they made an instagram filter for adding CA to videos and someone went crazy with it and applied it 10 times.
If this quality is the best they've got to put in a promo video, it is no wonder they barely show footage from the cam at all and intermix it with high quality footage (especially as seen in the skateboard section) in a borderline deceptive manner.
