I just mostly use four K only because it's just more popular, more common. And anyway when I uploaded to YouTube and all the other from the other platforms, they're not going to put keep it in five k anyway, so what does it matter? So I shot always in four k and I like the look of the footage. I like some people say it's over saturated but I like it. But now we get to the Osmo action three and I like it a lot better
