Highlight Hunter allows you to bookmark your 'highlights' on the mountain. Just cover your GoPro lens with your hand when you do something you tight. When you run the footage through the software it will create a 30 second clip for each 'highlight.'
I like the idea because I am lazy and don't want to spend the time watching through hours of go pro footage to find the best clips. Highlight Hunter saved me the trouble.
Heres a link to their website where they have more info and a free download version:
Let me know what you think.
