Hi,
can someone help me please with "protune" effect from goprostudio? - I try play with bezier curves, sharpen, saturation, but my result is still poor - I found (for example) this: http://thediveo-e.blogspot.cz/2013/10/g ... rline.html , but the result is diferent 

What exactly is "poor"? Can you show some stills?

Depending on frame size you'll need to tweak the sharpening parameters, they usually differ for 2.7k from 1080p respectively.

Do you use a H3 Black Edition or a H3+? For the latter individual H3+ cams seem to have clearly visible tinting that GoPro seems to hide somehow during wb processing.
