I just bought he GoPro Hero HD cam for present and future productions, and I made first recordings, this is one of them. I recorded in mode "r3", which is 720p60, and used Cinema Tools to conform the clip to 25 frames a second to get the slow motion.

I needed to transcode the clip first (I choose ProRes 422). Before uploading the file, I transcoded to H264. So, lots of messing around with the codecs.
