Sharpness -3 ?

[Mossie]

Just about everybody here recommends sharpness -3. However when I've tried it, even after post editing it looks absolutely terrible compared to sharpness 0. I've been using GoPro software suite and IMovie for editing my videos, so I'm wondering if a I should use something better if I want to get better results from -3. I've tried -1 and that's not much better either.

I did some experimentation and I tend to agree - if 4k output is your target.
