This was a video request by WeSmashRC who wanted a basic idea on how to make his camera footage look a little more like a GoPro. Keep in mind that the Hero2, Hero3 White, Silver and Black all look a little different to each other so you're never going to make footage look exactly like a particular GoPro. Having said that generally GoPro cameras tend to produce warm colours and punchy image quality.
The only thing I forgot to do on this video was increase the saturation of the overall image.
