Some recent comparison footage for Gizmodo.
Note: The reason we used the Hero4 Silver instead of the Black is because we were shooting at 1080p 30fps, and at that frame rate/resolution, the Black and the Silver are literally indistinguishable. They have the same exact optics and the same exact sensor. The Black just has a better processor which allows it to achieve higher frame rates. You can see the Black's 4K 30fps and 1080p 120fps in some of my other recent videos.
