I just want to throw this out there that it really does matter the trim level of gopro you buy. Standard, White, Silver, Black in that does dictate your picture quality. They do not shoot the same in equal resolution settings. For example, 1080p30 on a white is noticably lower quality than 1080p30 on a silver.
I shot all of 2014 riding season on a white. Then the usb slot broke and I bought a silver basically because that's what they had at the store. On paper they listed the same for the setting I record on. But once I looked at the videos it's a huge difference. No changes to my rendering settings.
You can see what I'm talking about if you look at my most recent vids (silver), and my vids in the 2014/early 2015 timeline (white).
