|The GoPro Hero3 Black|
Here is the treated footage and a link to the 1080p YouTube version.
So to me it is quite smooth and at first look, fairly acceptable, but looking at it more carefully the girl looks like she has been rotoscoped into the video and around her border there is a lot of blurry and incorrect pixels. Here are two screen grabs of an original frame followed by an interpolated Twixtor frame.
