I recently upgraded to the iPhone 6S. I plan on recording videos for daily use however i wanted to know what is the best setting to have when using my new 6S for video recording purposes. Specifically resolution (clearer) vs frame rate (smoother). Does the video look better if it is recorded in 4K 30fps or 1080p 60fps. I personally do not currently own any monitor to view 4K content on but i do plan on upgrading to a 5K iMac eventually. File size is not an issue.
