Could you give your expo settings? I seem to be all over the place because the settings I have don't seem to match what I expected.
I'm a total noob with a camera.
I used auto settings with white balance set to "cloudy"
The original footage was much more dull colored. It was a super gray cloudy day with no sun. I adjusted the settings like saturation contrast etc using GoPro studio as my editing tool. I just kept moving the sliders for each setting until the cars really seemed vivid.
No science or great understanding of how these things are supposed to work.
