Ok iv just started this editing thing since I got my mavic pro. The footage is butter smooth in 4k and looks amazing. After I put a short video together with Final Cut and export it to my desktop, the video is grainy and jittery. I don't know whats going on here. Need a little help. Im importing in the 4k formate when Final Cut asks. Im using a new 2017 MBP 13" so it shouldn't be a power problem. The video is only 2min long.
