After flying my X Star Premium, for the first time I was disappointed in trying to view the 4K video with my media players and with Cyberlink Power Director video editor. The video looked like a series of snap shots because the media players could not handle the 4K video. A buddy of mine, who pilots a DJI Phantom 4, put me onto a media player that can handle the 4K video. The player can be down loaded at mpc-hc.org. After down loading the mpc media player my 4K movie files played smoothly.
I came here with this exact complaint. Downloaded per your suggestion and am thrilled with the quality and smoothness of the video now. Thanks! Sent from my Nexus 5X using Tapatalk
