On my RC, I switch the video format to record 4K, but I left the video format container as MOV. I flew the drone above my house for a couple minutes then brought it back and USB connected the drone to my 4K TV to play straight off the card. I saw little to no difference between that video and all the others on the same card I've recorded in HD 1080P. What else do I need to do in addition to switching to 4K?
