The native app in video mode. 4k60 with both OIS and EIS enabled for stability. I sometimes use Pro video mode and other times use the new BlackMagic camera app for ultimate control if I ever need that, but 95% of the time it's normal video mode. All recordings are edited in YouCut Pro where I can export to 4k60 and apply some light colour grading to give the cinematic look with a subtle black contrast lift.
Any reason to go 4K60 over 4K30? A personal preference thing? I always found having the higher frames gives it that soap opera feel which I dislike.
Also where is the link to your settings? I remember seeing you post them in the past
