Finaly, I gave in and got one of these GoPro Hero4 (Black edition) action cameras. Indeed, a nice little toy. It was a rainy day, when I decided to try it out....of course no issue for the GoPro, as it is waterproof.
The GoPro was set to 120 fps (full HD) and afterwards slowed down to 60 fps in Adobe Premiere Pro. The time warp effect (super slow motion) and color grading was created in Adobe After Effects.
Also, a couple of magpies came across the GoPro. Here, the footage was just slowed down from 120 fps to 30 fps and color graded in Adobe Premiere Pro.
