I gave up on the Protune app. Seemed buggy and frustrating to me, but that could be me. Had no better luck with the premium (trial version).
I'm currently shooting 2.7k/30fps, protune ON, sharpen LOW, white balance AUTO. Have been shooting fov WIDE but may switch to medium (I think there's a medium) when I get the 3d gimbal.
In Premiere Pro, I will apply warp stabilizer if needed and distortion correction in After Effects, then,
Unsharp mask, 80%, 2.5 radius
Three way color corrector for saturation mostly,
LUT buddy with the Cineform LUT,
Brightness and contrast.
Lift mids and shadows as necessary.
I'm not a colorist. This is a serious profession and you can get off on a ditch easily if you don't know what you're doing. I've gotten to this workflow by trial and error mostly, and asking people who are smarter than me.
Here's a short sequence I put together last week, in no particular order just slammed together. Have just entered this hobby and love it. I did a lot of shooting prior to this with large camera rigs on Tyler mounts mostly but other rigs as well. The same principles apply really. But you can always walk away from the crash.

The first shot was pretty drab but the rest were done during golden hour. Stabilized one shot.. I think the first. All shot with the above settings.
